Project Management: Scope Creep (Definitions)

"Adding features and functionality (project scope) without addressing the effects on time, costs, and resources, or without customer approval." (Cynthia Stackpole, "PMP® Certification All-in-One For Dummies®", 2011)

"The tendency for people to sneak extra work and outputs into the project’s list of responsibilities. Can cause a project to fail under the burden of additional work without the corresponding resources." (Mike Clayton, "Brilliant Project Leader", 2012)

"The uncontrolled expansion to product or project scope without adjustments to time, cost, and resources." (For Dummies, "PMP Certification All-in-One For Dummies, 2nd Ed.", 2013)

"Additional activities beyond the defined or expected scope of a project. Scope creep often results in missed deadlines and increased costs." (Darril Gibson, "Effective Help Desk Specialist Skills", 2014)

"When the original plans or goals of a project expand. Common with projects, particularly poorly planned projects." (Weiss, "Auditing IT Infrastructures for Compliance, 2nd Ed", 2015)

"When features, functions, or attributes are added to a product during development that goes beyond the agreed-upon product requirements. When this condition occurs, the product is said to be experiencing scope creep. Scope creep is generally considered to be the number one cause of cost and schedule overruns in development projects. (Alternatively, this is sometimes called feature creep.)" (Steven Haines, "The Product Manager's Desk Reference", 2008)

"Adding features and functionality (project scope) without addressing the effects on time, costs, and resources, or without customer approval." (Jeffrey K Pinto, "Project Management: Achieving Competitive Advantage 5th Ed.", 2018)

"The insidious expansion of the product scope (i.e., expected functionality of the product, service, system, or result) that also expands or increases the project scope (i.e., the amount of work required) without a commensurate adjustment to or trade-off in the schedule, budget, resources, and/or quality, resulting in increased risk for the Performing Organization." (H James Harrington & William S Ruggles, "Project Management for Performance Improvement Teams", 2018)

"Also called requirement creep, this refers to uncontrolled changes in a project’s scope. Scope creep can occur when the scope of a project is not properly defined, documented and controlled. Typically, the scope increase consists of either new products or new features of already approved products. Hence, the project team drifts away from its original purpose. Because of one’s tendency to focus on only one dimension of a project, scope creep can also result in a project team overrunning its original budget and schedule. For example, scope creep can be a result of poor change control, lack of proper identification of what products and features are required to bring about the achievement of project objectives in the first place, or a weak project manager or executive sponsor."
