🧭Business Intelligence: A Software Engineer's Perspective (Part VII: Think for Yourself!)

Business Intelligence Series

After almost a quarter-century of professional experience the best advice I could give to younger professionals is to "gather information and think for themselves", and with this the reader can close the page and move forward! Anyway, everybody seems to be looking for sudden enlightenment with minimal effort, as if the effort has no meaning in the process!

In whatever endeavor you are caught, it makes sense to do upfront a bit of thinking for yourself - what's the task, or more general the problem, which are the main aspects and interpretations, which are the goals, respectively the objectives, how a solution might look like, respectively how can it be solved, how long it could take, etc. This exercise is important for familiarizing yourself with the problem and creating a skeleton on which you can build further. It can be just vague ideas or something more complex, though no matter the overall depth is important to do some thinking for yourself!

Then, you should do some research to identify how others approached and maybe solved the problem, what were the justifications, assumptions, heuristics, strategies, and other tools used in sense-making and problem solving. When doing research, one should not stop with the first answer and go with it. It makes sense to allocate a fair amount of time for information gathering, structuring the findings in a reusable way (e.g. tables, mind maps or other tools used for knowledge mapping), and looking at the problem from the multiple perspectives derived from them. It's important to gather several perspectives, otherwise the decisions have a high chance of being biased. Just because others preferred a certain approach, it doesn't mean one should follow it, at least not blindly!

The purpose of research is multifold. First, one should try not to reinvent the wheel. I know, it can be fun, and a lot can be learned in the process, though when time is an important commodity, it's important to be pragmatic! Secondly, new information can provide new perspectives - one can learn a lot from other people’s thinking. The pragmatism of problem solvers should be combined, when possible, with the idealism of theories. Thus, one can make connections between ideas that aren't connected at first sight.

Once a good share of facts was gathered, you can review the new information in respect to the previous ones and devise from there several approaches worthy of attack. Once the facts are reviewed, there are probably strong arguments made by others to follow one approach over the others. However, one can show that has reached a maturity when is able to evaluate the information and take a decision based on the respective information, even if the decision is not by far perfect.

One should try to develop a feeling for decision making, even if this seems to be more of a gut-feeling and stressful at times. When possible, one should attempt to collect and/or use data, though collecting data is often a luxury that tends to postpone the decision making, respectively be misused by people just to confirm their biases. Conversely, if there's any important benefit associated with it, one can collect data to validate in time one's decision, though that's a more of a scientist’s approach.

I know that's easier to go with the general opinion and do what others advise, especially when some ideas are popular and/or come from experts, though then would mean to also follow others' mistakes and biases. Occasionally, that can be acceptable, especially when the impact is neglectable, however each decision we are confronted with is an opportunity to learn something, to make a difference!

🧭🚥Business Intelligence: Key Performance Indicators [KPI] (Between Certainty and Uncertainty)

Business Intelligence Series

Despite the huge collection of documented Key Performance Indicators (KPIs) and best practices on which KPIs to choose, choosing a reliable set of KPIs that reflect how the organization performs in achieving its objectives continues to be a challenge for many organizations. Ideally, for each objective there should be only one KPIs that reflects the target and the progress made, though is that realistic?

Let's try to use the driver's metaphor to exemplify several aspects related to the choice of KPIs. A driver's goal is to travel from point A to point B over a distance d in x hours. The goal is SMART (Specific, Measurable, Achievable, Relevant, and Time-bound) if the speed and time are realistic and don't contradict Physics, legal or physical laws. The driver can define the objective as "arriving on time to the destination". 

One can define a set of metrics based on the numbers that can be measured. We have the overall distance and the number of hours planned, from which one can derive an expected average speed v. To track a driver's progress over time there are several metrics that can be thus used: e.g., (1) the current average speed, (2) the number of kilometers to the destination, (3) the number of hours estimated to the destination. However, none of these metrics can be used alone to denote the performance alone. One can compare the expected with the current average speed to get a grasp of the performance, and probably many organizations will use only (1) as KPI, though it's needed to use either (2) or (3) to get the complete picture. So, in theory two KPIs should be enough. Is it so?

When estimating (3) one assumes that there are no impediments and that the average speed can be attained, which might be correct for a road without traffic. There can be several impediments - planned/unplanned breaks, traffic jams, speed limits, accidents or other unexpected events, weather conditions (that depend on the season), etc. Besides the above formula, one needs to quantify such events in one form or another, e.g., through the perspective of the time added to the initial estimation from (3). However, this calculation is based on historical values or navigator's estimation, value which can be higher or lower than the final value. 

Therefore, (3) is an approximation for which is needed also a confidence interval (± t hours). The value can still include a lot of uncertainty that maybe needs to be broken down and quantified separately upon case to identify the deviation from expectations, e.g. on average there are 3 traffic jams (4), if the road crosses states or countries there may be at least 1 control on average (5), etc. These numbers can be included in (3) and the confidence interval, and usually don't need to be reported separately, though probably there are exceptions. 

When planning, one needs to also consider the number of stops for refueling or recharging the car, and the average duration of such stops, which can be included in (3) as well. However, (3) slowly becomes  too complex a formula, and even if there's an estimation, the more facts we're pulling into it, the bigger the confidence interval's variation will be. Sometimes, it's preferable to have instead two-three other metrics with a low confidence interval than one with high variation. Moreover, the longer the distance planned, the higher the uncertainty. One thing is to plan a trip between two neighboring city, and another thing is to plan a trip around the world. 

Another assumption is that the capability of the driver/car to drive is the same over time, which is not always the case. This can be neglected occasionally (e.g. one trip), though it involves a risk (6) that might be useful to quantify, especially when the process is repeatable (e.g. regular commuting). The risk value can increase considering new information, e.g. knowing that every a few thousand kilometers something breaks, or that there's a traffic fine, or an accident. In spite of new information, the objective might also change. Also, the objective might suffer changes, e.g. arrive on-time safe and without fines to the destination. As the objective changes or further objectives are added, more metrics can be defined. It would make sense to measure how many kilometers the driver covered in a lifetime with the car (7), how many accidents (8) or how many fines (9) the driver had. (7) is not related to a driver's performance, but (8) and (9) are. 

As can be seen, simple processes can also become very complex if one attempts to consider all the facts and/or quantify the uncertainty. The driver's metaphor applies to a simple individual, though once the same process is considered across the whole organization (a group of drivers), the more complexity is added and the perspective changes completely. E.g., some drivers might not even reach the destination or not even have a car to start with, and so on. Of course, with this also the objectives change and need to be redefined accordingly. 

The driver's metaphor is good for considering planning activities in which a volume of work needs to be completed in a given time and where a set of constraints apply. Therefore, for some organizations, just using two numbers might be enough for getting a feeling for what's happening. However, as soon one needs to consider other aspects like safety or compliance (considered in aggregation across many drivers), there might be other metrics that qualify as KPIs.

It's tempting to add two numbers and consider for example (8) and (9) together as the two are events that can be cumulated, even if they refer to different things that can overlap (an accident can result in a fine and should be counted maybe only once). One needs to make sure that one doesn't add apples with juice - the quantified values must have the same unit of measure, otherwise they might need to be considered separately. There's the tendency of mixing multiple metrics in a KPI that doesn't say much if the units of measure of its components are not the same. Some conversions can still be made (e.g. how much juice can be obtained from apples), though that's seldom the case.

𖣯Strategic Management: The Impact of New Technologies (Part II - The Technology-oriented Patient)

Looking at the way data, information and knowledge flow through an organization, with a little imagination one can see the resemblance between an organization and the human body, in which the networks created by the respective flows spread through organization as nervous, circulatory or lymphatic braids do, each with its own role in the good functioning of the organization. Each technology adopted by an organization taps into these flows creating a structure that can be compared with the nerve plexus, as the various flows intersect in such points creating an agglomeration of nerves and braids.

The size of each plexus can be considered as proportional to the importance of the technology in respect to the overall structure. Strategic technologies like ERP, BI or planning systems, given their importance (gravity), resemble with the organs from the human body, with complex networks of braids in their vicinity. Maybe the metaphor is too far-off, though it allows stressing the importance of each technology in respect to its role and the good functioning of the organization. Moreover, each such structure functions as pressure points that can in extremis block any of the flows considered, a long-term block having important effects.

The human organism is a marvelous piece of work reflecting the grand design, however in time, especially when neglected or driven by external agents, diseases can clutch around any of the parts of the human body, with all the consequences deriving from this. On the other side, an organization is a hand-made structure found in continuous expansion as new technologies or resources are added. Even if the technologies are at peripheral side of the system, their good or bad functioning can have a ripple effect trough the various networks.

Replacing any of the above-mentioned strategic systems can be compared with the replacement of an organ in the human body, having a high degree of failure compared with other operations, being complex in nature, the organism needing long periods to recover, while in extreme situations the convalescence prolongs till the end. Fortunately, organizations seem to be more resilient to such operations, though that’s not necessarily a rule. Sometimes all it takes is just a small mistake for making the operation fail.

The general feeling is that ERP and BI implementations are taken too lightly by management, employees and implementers. During the replacement operation one must make sure not only that the organ fits and functions as expected, but also that the vital networks regained their vitality and function as expected, and the latter is a process that spans over the years to come. One needs to check the important (health) signs regularly and take the appropriate countermeasures. There must be an entity having the role of the doctor, who/which has the skills to address adequately the issues.

Moreover, when the physical structure of an organization is affected, a series of micro-operations might be needed to address the deformities. Unfortunately, these areas are seldom seen in time, and can require a sustained effort for fixing, while a total reconstruction might apply. One works also with an amorphous and ever-changing structure that require many attempts until a remedy is found, if a remedy is possible after all.

Even if such operations are pretty well documented, often what organizations lack are the skilled resources needed during and post-implementation, resources that must know as well the patient, and ideally its historical and further health preconditions. Each patient is different and quite often needs its own treatment/medication. With such changes, the organization lands itself on a discovery journey in which the appropriate path can easily deviate from the well-trodden paths.

💼Project Management: Project Execution (Part IV: Projects' Dynamics II - Motion)

Motion is the action or process of moving or being moved between an initial and a final or intermediate point. From the tinniest endeavors to the movement of the planets and beyond, everything is governed by motion. If the laws of nature seem to reveal an inner structural perfection, the activities people perform are quite often far from perfect, which is acceptable if we consider that (almost) everything is a learning process. What is probably less acceptable is the volume of inefficient motion we can easily categorize sometimes as waste.

The waste associated with motion can take many forms: sorting through a pile of tools to find the right one, searching for information, moving back and forth to reach a destination or achieve a goal, etc. Suboptimal motion can have important effects for an organization resulting in reduced productivity, respectively higher costs.

If for repetitive activities that involve a certain degree of similarity can be found typically a way to optimize the motion, the higher the uncertainty of the steps involved, the more difficult it becomes to optimize it. It’s the case of discovery endeavors in which the path between start and destination can’t be traced beforehand, respectively when the destination or path in between can’t be depicted to the needed level of detail. A strategy’s implementation, ERP implementations and other complex projects, especially the ones dealing with new technologies and/or incomplete knowledge, tend to be exploratory in nature and thus fall under this latter type a motion.

In other words, one must know at minimum the starting point, the destination, how to reach it and what it takes to reach it – resources, knowledge, skillset. When one has all this information one can go on and estimate how long it will take to reach the destination, though the estimate reflects the information available as well estimator’s skills in translating the information into a realistic roadmap. Each new information has the potential of impacting considerably the whole process, in extremis to the degree that one must start the journey anew. The complexity of such projects and the volume of uncertainty can make estimation difficult if not impossible, no matter how good estimators' skills are. At best an estimator can come with a best- and worst-case estimation, both however dependent on the assumptions made.

Moreover, complex projects are sensitive to the initial conditions or auspices under which they start. This sensitivity can turn a project in a totally different direction or pace, that can be reinforced positively or negatively as the project progresses. It’s a continuous interplay between internal and external factors and components that can create synergies or have adverse effects with the potential of reaching tipping points.

Related to the initial conditions, as the praxis sometimes shows, for entities found in continuous movement (like organizations) it’s also important to know from where one’s coming (and at what speed), as the previous impulse (driving force) can be further used or stirred as needed. Metaphorically, a project will need a certain time to find the right pace if it lacks the proper impulse.

Unless the team is trained to play and plays like an orchestra, the impact of deviations from expectations can be hardly quantified. To minimize the waste, ideally a project’s journey should minimally deviate from the optimal path, which can be challenging to achieve as a project’s mass can pull the project in one direction or the other. The more the project advances the bigger the mass, fact which can make a project unstoppable. When such high-mass projects are stopped, their impulse can continue to haunt the organization years after.

🤝Governance: Responsibility (Just the Quotes)

"Weak character coupled with honored place, meager knowledge with large plans, limited powers with heavy responsibility, will seldom escape disaster." ("I Ching" ["Book of Changes"], cca. 600 BC)

"The only way for a large organization to function is to decentralize, to delegate real authority and responsibility to the man on the job. But be certain you have the right man on the job." (Robert E Wood, 1951)

"[...] authority - the right by which superiors are able to require conformity of subordinates to decisions - is the basis for responsibility and the force that binds organization together. The process of organizing encompasses grouping of activities for purposes of management and specification of authority relationships between superiors and subordinates and horizontally between managers. Consequently, authority and responsibility relationships come into being in all associative undertakings where the superior-subordinate link exists. It is these relationships that create the basic character of the managerial job." (Harold Koontz & Cyril O Donnell, "Principles of Management", 1955)

"[...] authority for given tasks is limited to that for which an individual may properly held responsible." (Harold Koontz & Cyril O Donnell, "Principles of Management", 1955)

"If charts do not reflect actual organization and if the organization is intended to be as charted, it is the job of effective management to see that actual organization conforms with that desired. Organization charts cannot supplant good organizing, nor can a chart take the place of spelling out authority relationships clearly and completely, of outlining duties of managers and their subordinates, and of defining responsibilities." (Harold Koontz & Cyril O Donnell, "Principles of Management", 1955)

"Responsibility cannot be delegated. While a manager may delegate to a subordinate authority to accomplish a service and the subordinate in turn delegate a portion of the authority received, none of these superiors delegates any of his responsibility. Responsibility, being an obligation to perform, is owed to one's superior, and no subordinate reduces his responsibility by assigning the duty to another. Authority may be delegated, but responsibility is created by the subordinate's acceptance of his assignment." (Harold Koontz & Cyril O Donnell, "Principles of Management", 1955)

"Viewed internally with respect to the enterprise, responsibility may be defined as the obligation of a subordinate, to whom a superior has assigned a duty, to perform the service required. The essence of responsibility is, then, obligation. It has no meaning except as it is applied to a person." (Harold Koontz & Cyril O Donnell, "Principles of Management", 1955)

"You can delegate authority, but you can never delegate responsibility by delegating a task to someone else. If you picked the right man, fine, but if you picked the wrong man, the responsibility is yours - not his." (Richard E Krafve, The Boston Sunday Globe, 1960)

"Modern organization makes demands on the individual to learn something he has never been able to do before: to use organization intelligently, purposefully, deliberately, responsibly [...] to manage organization [...] to make [...] his job in it serve his ends, his values, his desire to achieve." (Peter F Drucker, The Age of Discontinuity, 1968)

"[Management by objectives is] a process whereby the superior and the subordinate managers of an enterprise jointly identify its common goals, define each individual's major areas of responsibility in terms of the results expected of him, and use these measures as guides for operating the unit and assessing the contribution of each of its members." (Robert House, "Administrative Science Quarterly", 1971)

"'Management' means, in the last analysis, the substitution of thought for brawn and muscle, of knowledge for folkways and superstition, and of cooperation for force. It means the substitution of responsibility for obedience to rank, and of authority of performance for authority of rank. (Peter F Drucker, "People and Performance", 1977)

"[...] the first criterion in identifying those people within an organization who have management responsibility is not command over people. It is responsibility for contribution. Function rather than power has to be the distinctive criterion and the organizing principle." (Peter F Drucker, "People and Performance", 1977)

"The productivity of work is not the responsibility of the worker but of the manager." (Peter F Drucker, "Management in Turbulent Times", 1980)

"By assuming sole responsibility for their departments, managers produce the very narrowness and self-interest they deplore in subordinates. When subordinates are relegated to their narrow specialties, they tend to promote their own practical interests, which then forces other subordinates into counter-advocacy. The manager is thereby thrust into the roles of arbitrator, judge, and referee. Not only do priorities become distorted, but decisions become loaded with win/lose dynamics. So, try as the manager might, decisions inevitably lead to disgruntlement and plotting for the next battle." (David L Bradford & Allan R Cohen, "Managing for Excellence", 1984)

"The man who delegates responsibilities for running the company, without knowing the intimate details of what is involved, runs the enormous risk of rendering himself superfluous." (Harold Geneen, "Managing", 1984)

"Leadership is the total effect you have on the people and events around you. This effect is your influence. Effective leading is being consciously responsible for your organizational influence. [...] The essence of leadership is knowing that YOU CAN NEVER NOT LEAD. You lead by acts of commission and acts of omission." (Kenneth Schatz & Linda Schatz, "Managing by Influence", 1986)

"Looking for differences between the more productive and less productive organizations, we found that the most striking difference is the number of people who are involved and feel responsibility for solving problems." (Michael McTague, "Personnel Journal", 1986)

"Management has a responsibility to explain to the employee how the routine job contributes to the business's objectives. If management cannot explain the value of the job, then it should be eliminated and the employee reassigned." (Douglas M Reid, Harvard Business Review, 1986)

"A systematic effort must be made to emphasize the group instead of the individual. [...] Group goals and responsibilities can usually overcome any negative reactions to the individual and enforce a standard of cooperation that is attainable by persuasion or exhortation." (Eugene Raudsepp, MTS Digest, 1987)

"An individual without information cannot take responsibility; an individual who is given information cannot help but take responsibility." (Jan Carlzon, "Moments of Truth", 1987)

"Executives have to start understanding that they have certain legal and ethical responsibilities for information under their control." (Jim Leeke, PC Week, 1987)

"If responsibility - and particularly accountability - is most obviously upwards, moral responsibility also reaches downwards. The commander has a responsibility to those whom he commands. To forget this is to vitiate personal integrity and the ethical validity of the system." (Roger L Shinn, "Military Ethics", 1987)

[...] quality assurance is the job of the managers responsible for the product. A separate group can't 'assure' much if the responsible managers have not done their jobs properly. [...] Managers should be held responsible for quality and not allowed to slough off part of their responsibility to a group whose name sounds right but which cannot be guaranteed quality if the responsible managers have not been able to do so." (Philip W. Metzger, "Managing Programming People", 1987)

"Responsibility is a unique concept [...] You may share it with others, but your portion is not diminished. You may delegate it, but it is still with you. [...] If responsibility is rightfully yours, no evasion, or ignorance or passing the blame can shift the burden to someone else. Unless you can point your finger at the man who is responsible when something goes wrong, then you have never had anyone really responsible." (Hyman G Rickover, "The Rickover Effect", 1992)

"If you treat people as though they are responsible, they tend to behave that way." (James P Lewis, "Project Planning, Scheduling, and Control" 3rd Ed., 2001)

"You can’t delegate responsibility without giving a person authority commensurate with it." (James P Lewis, "Project Planning, Scheduling, and Control" 3rd Ed., 2001)

"What do people do today when they don’t understand 'the system'? They try to assign responsibility to someone to fix the problem, to oversee 'the system', to coordinate and control what is happening. It is time we recognized that 'the system' is how we work together. When we don’t work together effectively putting someone in charge by its very nature often makes things worse, rather than better, because no one person can understand 'the system' well enough to be responsible. We need to learn how to improve the way we work together, to improve 'the system' without putting someone in charge, in order to make things work." (Yaneer Bar-Yam, "Making Things Work: Solving Complex Problems in a Complex World", 2004)

"In order to cultivate a culture of accountability, first it is essential to assign it clearly. People ought to clearly know what they are accountable for before they can be held to it. This goes beyond assigning key responsibility areas (KRAs). To be accountable for an outcome, we need authority for making decisions, not just responsibility for execution. It is tempting to refrain from the tricky exercise of explicitly assigning accountability. Executives often hope that their reports will figure it out. Unfortunately, this is easier said than done." (Sriram Narayan, "Agile IT Organization Design: For Digital Transformation and Continuous Delivery", 2015)

"Any software project must have a technical leader, who is responsible for all technical decisions made by the team and have enough authority to make them. Responsibility and authority are two mandatory components that must be present in order to make it possible to call such a person an architect." (Yegor Bugayenko, "Code Ahead", 2018)

"Responsibility means an inevitable punishment for mistakes; authority means full power to make them." (Yegor Bugayenko, "Code Ahead", 2018)

📊Graphical Representation: Graphics We Live by (Part V: Pie Charts in MS Excel)

From business dashboards to newspapers and other forms of content that capture the attention of average readers, pie charts seem to be one of the most used forms of graphical representation. Unfortunately, their characteristics make them inappropriate for displaying certain types of data, and of being misused. Therefore, there are many voices who advice against using them for any form of display.

It’s hard to agree with radical statements like ‘avoid (using) pie charts’ or ’pie charts are bad’. Each form of graphical representation (aka graphical tool, graphic) has advantages and disadvantages, which makes it appropriate or inappropriate for displaying data having certain characteristics. In addition, each tool can be easily misused, especially when basic representational practices are ignored. Avoiding one representational tool doesn’t mean that the use of another tool will be correct. Therefore, it’s important to make people aware of these aspects and let them decide which tools they should use. 

From a graphical tool is expected to represent and describe a dataset in a small area without distorting the reality, while encouraging the reader to compare the different pieces of information, when possible at different levels of details [1] or how they change over time. As form of communication, they encode information and meaning; the reader needs to be able to read, understand and think critically about graphics and data – what is known as graphical/data literacy.

A pie chart consists of a circle split into wedge-shaped slices (aka edges, segments), each slice representing a group or category (aka component). It resembles with the spokes of a wheel, however with a few exceptions they are seldom equidistant. The size of each slice is proportional to the percentage of the component when compared to the whole. Therefore, pie charts are ideal when displaying percentages or values that can be converted into percentages. Thus, the percentages must sum up to 100% (at least that’s readers’ expectation).

Within or besides the slices are displayed components’ name and sometimes the percentages or other numeric or textual information associated with them (Fig. 1-4).  The percentages become important when the slices seem to be of equal sizes. As long the slices have the same radius, comparison of the different components resumes in comparing arcs of circles or the chords defined by them, thing not always straightforward. 3-dimensional displays can upon case make the comparison more difficult.

The comparison increases in difficulty with the number of slices increases beyond a certain number. Therefore, it’s not recommended displaying more than 5-10 components within the same chart. If the components exceed this limit, the exceeding components can be summed up within an “other” component. 

Within a graphic one needs a reference point that can be used as starting point for exploration. Typically for categorical data this reference point is the biggest or the smallest value, the other values being sorted in ascending, respectively descending order, fact that facilitates comparing the values. For pie charts, this would mean sorting the slices based on their sizes, except the slice for “others” which is typically considered last.

The slices can be filled optionally with meaningful colors or (hashing) patterns. When the same color pallet is used, the size can be reflected in colors’ hue, however this can generate confusion when not applied adequately. It’s recommended to provide further (textual) information when the graphical elements can lead to misinterpretations. 

Pie charts can be used occasionally for comparing the changes of the same components between different points in time, geographies (Fig. 5-6) or other types of segmentation. Having the charts displayed besides each other and marking each component with a characteristic color or pattern facilitate the comparison. 

⛁DBMS: Event Streaming Databases (More of a Kafka’s Story)

Event streaming architectures are architectures in which data are generated by different sources, and then processed, stored, analyzed, and acted upon in real-time by the different applications tapped into the data streams. An event streaming database is then a database that assures that its data are continuously up-to-date, providing specific functionality like management of connectors, materialized views and running queries on data-in-motion (rather than on static data). 

Reading about this type of technologies one can easily start fantasizing about the Web as a database in which intelligent agents can process streams of data in real-time, in which knowledge is derived and propagated over the networks in an infinitely and ever-growing flow in which the limits are hardly perceptible, in which the agents act as a mind disconnected in the end from the human intent. One is stroke by the fusing elements of realism and the fantastic aspects, more like in a Kafka’s story in which the metamorphosis of the technologies and social aspects can easily lead to absurd implications.

The link to Kafka was somehow suggested by Apache Kafka, an open-source distributed event streaming platform, which seems to lead the trends within this new-developing market. Kafka provides database functionality and guarantees the ACID (atomicity, concurrency, isolation, durability) properties of transactions while tapping into data streams. 

Data streaming is an appealing concept though it has some important challenges like data overload or over-flooding, the complexity derived from building specific (business) and integrity rules for processing the data, respectively for keeping data consistency and truth within the ever-growing and ever-changing flows. 

Data overload or over-flooding occurs when applications are not able to keep the pace with the volume of data or events fired with each change. Imagine the raindrops falling on a wide surface in which each millimeter or micrometer has its own rules for handling the raindrops and this at large scale. The raindrops must infiltrate into the surface to be processed and find their way to the beneath water flows, aggregating up to streams that could nurture seas or even oceans. Same metaphor can be applied to the data events, in which the data pervade applications accumulating in streams processed by engines to derive value. However heavy rains can easily lead to floods in which water aggregates at the surface. 

Business applications rely on predefined paths in which the flow of data is tidily linked to specific actions found themselves in processual sequences that reflect the material or cash flow. Any variation in the data flow from expectations will lead to inefficiencies and ultimately to chaos. Some benefit might be derived from data integrations between the business applications, however applications must be designed for this purpose and handle extreme behaviors like over-flooding. 

Data streams are maybe ideal for social media networks in which one broadcasts data through the networks and any consumer that can tap to the network can further use the respective data. We can see however the problems of nowadays social media – data, better said information, flow through the networks being changed as fit for purposes that can easily diverge from the initial intent. Moreover, information gets denatured, misused, overused to the degree that it overloads the networks, being more and more difficult to distinguish between reliable and non-reliable information. If common sense helps in the process of handling such information, not the same can be said about machines or applications. 

It will be challenging to deal with the vastness, vagueness, uncertainty, inconsistency, and deceit of the networks of the future, however data streaming more likely will have a future as long it can address such issues by design. 

🧭Business Intelligence: Perspectives (Part VI: Data Soup - Reports vs. Data Visualizations)

Business Intelligence Series

Considering visualizations, John Tukey remarked that ‘the greatest value of a picture is when it forces us to notice what we never expected to see’, which is not always the case for many of the graphics and visualizations available in organizations, typically in the form of simple charts and dashboards, quite often with no esthetics or meaning behind.

In general, reports are needed as source for operational activities, in which the details in form of raw or aggregate data are important. As one moves further to the tactical or strategic aspects of a business, visualizations gain in importance especially when they allow encoding data and information, respectively variations, trends or relations in smaller places with minimal loss of information.

There are also different aspects of visualizations that need to be considered. Modern tools allow rapid visualization and interactive navigation of data across different variables which is great as long one knows what is searching for, which is not always the case.

There are junk charts in which the data drowns in graphical elements that bring no value to the reader, in extremis even distorting the message/meaning.

There are graphics/visualizations that attempt bringing together and encoding multiple variables in respect to a theme, and for which a ‘project’ is typically needed as data is not ad-hoc available, don’t have the desired quality or need further transformations to be ready for consumption. Good quality graphics/visualizations require time and a good understanding of the business, which are not necessarily available into the BI/Analytics teams, and unfortunately few organizations do something in that direction, ignoring typically such needs. In this type of environments is stressed the rapid availability of data for decision-making or action-relevant insight, which depends typically on the consumer.

The story-telling capabilities of graphics/visualizations are often exaggerated. Yes, they can tell a story though stories need to be framed into a context/problem, some background and further references need to be provided, while without detailed data the graphics/visualizations are just nice representations in which each consumer understands what he can.

In an ideal world the consumer and the ‘designer’ would work together to identify the important data for the theme considered, to find the appropriate level of detail, respectively the best form of encoding. Such attempts can stop at table-based representations (aka reports), respectively basic or richer forms of graphical representations. One can consider reports as an early stage of the visualization process, with the potential to derive move value when the data allow meaningful graphical representations. Unfortunately, the time, data and knowledge available seldom make this achievable.

In addition, a well-designed report can be used as basis for multiple purposes, while a graphic/visualization can enforce more limitations. Ideal would be when multiple forms of representation (including reports) are combined to harness the value of data. Navigations from visualizations to detailed data can be useful to understand what happens; learning and understanding the various aspects being an iterative process.

It’s also difficult to demonstrate the value of insight derived from visualizations, especially when graphical literacy goes behind the numeracy and statistical literacy - many consumers lacking the skills needed to evaluate numbers and statistics adequately. If for a good artistic movie you need an assistance to enjoy the show and understand the message(s) behind it, the same can be said also about good graphics/visualizations. Moreover, this requires creativity, abstraction-based thinking, and other capabilities to harness the value of representations.

Given the considerable volume of requirements related to the need of basis data, reports will continue to be on high demand in organizations. In exchange visualizations can complement them by providing insights otherwise not available.

𖣯🧮Strategic Management: Simplicity VI (ERP Implementations' Story II)

Besides the witty sayings and theories advanced in defining what simplicity is about, life shows that there’s a considerable gap between theory and praxis. In the attempt at a definition, one is forced to pull more concepts like harmony, robustness, variety, balance, economy, or proportion, which can be grouped under organic unity or similar concepts. However, intuitionally one can advance the idea that from a cybernetic perspective simplicity is achieved when the information flows are not disrupted and don’t meet unnecessary resistance. By information here are considered the various data aggregations – data, information, knowledge, and eventually wisdom (aka DIKW pyramid) – though it can be extended to encompass materials, cash and vital energy.

One can go further and say that an organization is healthy when the various flows mentioned above run smoothly through the organization nourishing it. The comparison with the human body can go further and say that a blockage in the flow can cause minor headaches or states that can take a period of convalescence to recover from them. Moreover, the sustained effort applied by an organization can result in fatigue or more complex ailments or even diseases if the state is prolonged. 

For example, big projects like ERP implementations tend to suck the vital energy of an organization to the degree that it will take months to recover from the effort, while the changes in the other types of flow can lead to disruptions, especially when the change is not properly managed. Even if ERP implementations provide standard solutions for the value-added processes, they represent vendors’ perspective into the respective processes, which don’t necessarily fit an organization’s needs. One is forced then to make compromises either by keeping close to the standard or by expanding the standard processes to close the gap. Either way processual changes are implied, which affect the information flow, especially for the steps where further coordination is needed, respectively the data flow in respect to implementation or integration with the further systems. A new integration as well as a missing integration have the potential of disrupting the data and information flows.

The processual changes can imply changes in the material flow as the handling of the materials can change, however the most important impact is caused maybe by the processual bottlenecks, which can cause serious disruptions (e.g. late deliveries, production is stopped), and upon case also in the cash-flow (e.g. penalties for late deliveries, higher inventory costs). The two flows can be impacted by the data and information flows independently of the processual changes (e.g. when they have poor quality, when not available, respectively when don’t reach the consumer in timely manner). 

With a new ERP solution, the organization needs to integrate the new data sources into the existing BI infrastructure, or when not possible, to design and implement a new one by taking advantage of the technological advancements. Failing to exploit this potential will impact the other flows, however the major disruptions appear when the needed knowledge about business processes is not available in-house, in explicit and/or implicit form, before, during and after the implementation. 

Independently on how they are organized – in center of excellence or ad-hoc form – is needed a group of people who can manage the various flows and ideally, they should have the appropriate level of empowerment. Typically, the responsibility resides with key users, IT and one or two people from the management. Without a form of ‘organization’ to manage the flows, the organization will reside only on individual effort, which seldom helps reaching the potential. Independently of the number of resources involved, simplicity is achieved when the activities flow naturally.
