"A component or device with an input and an output whose inner workings need not be understood by or accessible to the user." (Marcia Kaufman et al, "Big Data For Dummies", 2013)

"Is a metaphor describing how people are unable to see or understand how technologies work and is particularly used to characterize the lack of understanding of how an algorithm works. While we can understand the outputs of artificial intelligence (AI) - in terms of recommendations, decisions and so on - the processes to achieve them are too complicated for us to understand. Concerns about the black box nature of AI center on its apparent lack of accountability, potential unseen biases and the inability to have clear visibility into what is driving an AI’s potentially life-changing decisions."

"In software engineering, it is a general reusable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.

[...] Design patterns deal specifically with problems at the level of software design." (Salvatore Scifo, "Accessing Grid Metadata through a Web Interface", 2009)

"A design pattern is a general, proven, and beneficial solution to a common, reoccurring problem in software design.

"General solution for a common problem that occurs when designing software. A design pattern is reusable, so that it might be applied in many systems that suffer of a common problem." (Márcio Ribeiro et al, "Recommending Mechanisms for Modularizing Mobile Software Variabilities", 2012)

"[...] a design pattern [...] describes a solution to a 'typical' software design problem. A pattern provides a general template for a solution that can be applied in many different situations. It describes the main elements of a solution in an abstract way that can be specialized for a specific problem at hand." (Michael T Goodrichet al, "Data Structures and Algorithms in Python", 2013)

"A design pattern is an abstract description of best practice that has worked successfully in different systems and environments, and it acts as a reusable solution that may be used in many situations. It is more a description or template on how to solve the problem within a particular context, rather than a finished solution." (Gerard O’Regan, "Concise Guide to Software Engineering: From Fundamentals to Application Methods", 2017)

(David Lyle & John G Schmidt, "Lean Integration: An Integration Factory Approach to Business Agility", 2010)

"A recurring combination of data and task management, separate from any specific algorithm. Patterns are universal in that they apply to and can be used in any programming system.

Includes detailed design, coding (for software), fabrication and inspection (for hardware), and unit (component) test. For software, detailed design and coding are usually combined. (2) The result of the process in (1). Also called construction." (Richard D Stutzke, "Estimating Software-Intensive Systems: Projects, Products, and Processes", 2005)

"The process of creating software from a design of that software. A physical database is an implementation of a database model." (Gavin Powell, "Beginning Database Design", 2006)

"Deploying a software solution in a company is accomplished through an iterative sequence of activities. These activities are bundled into an implementation project." (Janice M Roehl-Anderson, "IT Best Practices for Financial Managers", 2010)

"All organizational activities involved in the introduction, management, and acceptance of technology to support one or more organizational processes." (Linda Volonino & Efraim Turban, "Information Technology for Management" 8th Ed., 2011)

"Execution or fulfillment of a plan or design; putting into action." (Joan C Dessinger, "Fundamentals of Performance Improvement" 3rd Ed., 2012)

"How a piece of code actually goes about doing its job. Users of the code should not count on implementation details staying the same unless they are part of the published interface." (Jon Orwant et al, "Programming Perl" 4th Ed., 2012)

"The activity of making the essential requirements work in the real world." (James Robertson et al, "Complete Systems Analysis: The Workbook, the Textbook, the Answers", 2013)

"When used by programmers, this term usually means writing the code. When used by managers, this often means deployment." (Rod Stephens, "Beginning Software Engineering", 2015)

🌁Software Engineering: Rational Unified Process (Definitions)

"A customizable method framework providing guidance for a variety of project types and enterprise needs. RUP is an extension of OpenUP/Basic and is delivered through the IBM Rational Method Composer." (Bruce MacIsaac & Per Kroll, "Agility and Discipline Made Easy: Practices from OpenUP and RUP", 2006)

"A rigorous, four-phase software development process created by IBM Rational that is evolutionary in nature." (Pramod J Sadalage & Scott W Ambler, "Refactoring Databases: Evolutionary Database Design", 2006)

"An iterative software development process framework created by the Rational Software Corporation. RUP is not a single concrete prescriptive process, but rather an adaptable process framework, intended to be tailored by development organizations and software project teams, who select the elements of the process that are appropriate for their needs." (Mark S Merkow & Lakshmikanth Raghavan, "Secure and Resilient Software Development", 2010)

"An Iterative software development process framework created by the Rational Software Corporation, a division of IBM since 2003. RUP is not a single concrete prescriptive process but rather an adaptable process framework intended to be tailored by the development organizations and software project teams that will select the elements of the process that are appropriate for their needs. RUP is a specific implementation of the unified process." (Pierre Pureur & Murat Erder, "Continuous Architecture", 2015)

"A proprietary adaptable iterative software development process framework consisting of four project lifecycle phases: inception, elaboration, construction and transition." (IQBBA)

🌁Software Engineering: Error (Definitions)

"(1) The difference between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition. For example, a difference of 30 meters between a computed result and the correct result. (2) An incorrect step, process, or data definition. For example, an incorrect instruction in a computer program. (3) An incorrect result. For example, a computed result of 12 when the correct result is 10. (4) A human action that produces an incorrect result. For example, an incorrect action on the part of a programmer or operator."  (IEEE," IEEE Standard Glossary of Software Engineering Terminology", 1990)

"A problem or defect in code that usually causes a program to halt." (Michael Fitzgerald, "Learning Ruby", 2007)

"A systematic fault or mistake." (Bruce P Douglass, "Real-Time Agility: The Harmony/ESW Method for Real-Time and Embedded Systems Development", 2009)

"A human action that produces an incorrect result. Also a general, informally used term for terms like mistake, fault, defect, bug, failure." (Tilo Linz et al, "Software Testing Foundations, 4th Ed", 2014)

"Act that departs from what should be done; imprudent deviation, unintentional mistake or omission." (Tom Klammer, "Statement of Cash Flows: Preparation, Presentation, and Use", 2018)

"An error is that part of the system state that may cause a subsequent failure: a failure occurs when an error reaches the service interface and alters the service." (O Sami Saydjari, "Engineering Trustworthy Systems: Get Cybersecurity Design Right the First Time", 2018)

"Design flaw or malfunction that causes a failure of one or more CIs/services" (ITIL)

"Human action that produces an incorrect result." (Software Quality Assurance) [after IEEE 610] 

"The difference between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition. For example, a difference of 30 meters between a computed result and the correct result. (2) A human action that causes an incorrect result. See discussion under failure. See also defect, fault, mistake, problem." (IEEE Std 610.12-1990)
