Functionality Creep
Scope creep (also called requirement creep, or kitchen sink syndrome) in project management refers to changes, continuous or uncontrolled growth in a project’s scope, at any point after the project begins. This can occur when the scope of a project is not properly defined, documented, or controlled. It is generally considered harmful. It is related to but distinct from feature creep, because feature creep refers to features, and scope creep refers to the whole project. Common causes Poorly defined project scope Ineffective project management communication between a client and the project manager is a leading effect of project scope creep. An assignment that is not understood correctly will turn out to be completely different from clients vision. With that being said clients can also be to blame as they may not see a clear vision of what they want. Failure to capture all requirements Properly defining project scope requires thorough investigation by the project manager du ...

Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scope (project Management)
In project management, scope is the defined features and functions of a product, or the scope of work needed to finish a project. Scope involves getting information required to start a project, including the features the product needs to meet its stakeholders' requirements. Project scope is oriented towards the work required and methods needed, while product scope is more oriented toward functional requirements. If requirements are not completely defined and described and if there is no effective change control in a project, scope or requirement creep may ensue. Scope management is listing the items to be produced or tasks to be done; their required quantity, quality, and variety; the time and resources available and agreed upon; and modifying the variable constraints by dynamic flexible juggling in the event of changed circumstances. See also *Cost overrun *Requirements management *Scope statement In project management, scope statements can take many forms depending on the t ...

Second-system Effect
The second-system effect or second-system syndrome is the tendency of small, elegant, and successful systems to be succeeded by over-engineered, bloated systems, due to inflated expectations and overconfidence. The phrase was first used by Fred Brooks in his book ''The Mythical Man-Month'', first published in 1975. It described the jump from a set of simple operating systems on the IBM 700/7000 series to OS/360 on the 360 series, which happened in 1964.

The Mythical Man-Month
''The Mythical Man-Month: Essays on Software Engineering'' is a book on software engineering and project management by Fred Brooks first published in 1975, with subsequent editions in 1982 and 1995. Its central theme is that adding manpower to a software project that is behind schedule delays it even longer. This idea is known as Brooks's law, and is presented along with the second-system effect and advocacy of prototyping. Brooks's observations are based on his experiences at IBM while managing the development of OS/360. He had added more programmers to a project falling behind schedule, a decision that he would later conclude had, counter-intuitively, delayed the project even further. He also made the mistake of asserting that one project—involved in writing an ALGOL compiler—would require six months, regardless of the number of workers involved (it required longer). The tendency for managers to repeat such errors in project development led Brooks to quip that his book is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mission Creep
Mission creep is the gradual or incremental expansion of an intervention, project or mission, beyond its original scope, focus or goals, a ratchet effect spawned by initial success. Mission creep is usually considered undesirable due to how each success breeds more ambitious interventions until a final failure happens, stopping the intervention entirely. The term was originally applied exclusively to military operations, but has recently been applied to many different fields, which itself is an example of mission creep. The phrase first appeared in 1993, in articles published in ''The Washington Post'' and in ''The New York Times'' concerning the United Nations peacekeeping mission during the Somali Civil War. History Somali Civil War The first two articles to use the term in the ''Washington Post'' were both by columnist Jim Hoagland ("Prepared for Non-Combat", April 15, 1993, and ''Beware 'mission creep' In Somalia'', July 20, 1993). The ''New York Times'' used the term for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instruction Creep
Instruction creep or rule creep occurs when instructions or rules accumulate over time until they are unmanageable or inappropriate. It is a type of scope creep. The accumulation of bureaucratic requirements results in overly complex procedures that are often misunderstood, irritating, time-wasting, or ignored. Instruction creep is common in complex organizations, where rules and guidelines are created by changing groups of people over extended periods of time. The constant state of flux in such groups often leads them to add or modify instructions, rather than simplifying, consolidating, or generalizing existing ones. This can result in a loss of clarity, efficiency, and communication, or even of consistency. Alternatives to instruction creep include applying the KISS principle, articulating general principles rather than specific rules, and trusting people to use their best judgment. The fundamental fallacy of instruction creep is believing that people read instructions wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escalation Of Commitment
Escalation of commitment is a human behavior pattern in which an individual or group facing increasingly negative outcomes from a decision, action, or investment nevertheless continue the behavior instead of altering course. The actor maintains behaviors that are irrational, but align with previous decisions and actions. Economists and behavioral scientists use a related term, ''sunk-cost fallacy'', to describe the justification of increased investment of money or effort in a decision, based on the cumulative prior investment ("sunk cost") despite new evidence suggesting that the future cost of continuing the behavior outweighs the expected benefit. In sociology, ''irrational escalation of commitment'' or ''commitment bias'' describe similar behaviors. The phenomenon and the sentiment underlying them are reflected in such proverbial images as "Throwing good money after bad", or "In for a penny, in for a pound", or "It's never the wrong time to make the right decision", or "I ...

Planning Poker
Planning poker, also called Scrum poker, is a consensus-based, gamified technique for estimating, mostly used for timeboxing in '' Agile principles''. In planning poker, members of the group make estimates by playing numbered cards face-down to the table, instead of speaking them aloud. The cards are revealed, and the estimates are then discussed. By hiding the figures in this way, the group can avoid the cognitive bias of anchoring, where the first number spoken aloud sets a precedent for subsequent estimates. Planning poker is a variation of the Wideband delphi method. It is most commonly used in agile software development, in particular in Scrum and Extreme Programming. The method was first defined and named by James Grenning in 2002 and later popularized by Mike Cohn in the book ''Agile Estimating and Planning'', whose company trade marked the term and a digital online tool. Process Rationale The reason to use planning poker is to avoid the influence of the other par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cost Overrun
A cost overrun, also known as a cost increase or budget overrun, involves unexpected incurred costs. When these costs are in excess of budgeted amounts due to a value engineering underestimation of the actual cost during budgeting, they are known by these terms. Cost overruns are common in infrastructure, building, and technology projects. For IT projects, a 2004 industry study by the Standish Group found an average cost overrun of 43 percent; 71 percent of projects came in over budget, exceeded time estimates, and had estimated too narrow a scope; and total waste was estimated at $55 billion per year in the US alone. Many major construction projects have incurred cost overruns; cost estimates used to decide whether important transportation infrastructure should be built can mislead grossly and systematically. Cost overrun is distinguished from cost escalation, which is an ''anticipated'' growth in a budgeted cost due to factors such as inflation. Causes Recent works by Ahia ...

Project
A project is any undertaking, carried out individually or collaboratively and possibly involving research or design, that is carefully planned to achieve a particular goal. An alternative view sees a project managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations". A project may be a temporary (rather than a permanent) social system ( work system), possibly staffed by teams (within or across organizations) to accomplish particular tasks under time constraints. A project may form a part of wider programme management or function as an ''ad hoc'' system. Note that open-source software "projects" or artists' musical "projects" (for example) may lack defined team-membership, precise planning and/or time-limited durations. Overview The word ''project'' comes from the Latin word ''projectum'' from the Latin verb ''proicere'', "before an action," which in turn comes from ''pro-'', which d ...

Anti-pattern
An anti-pattern in software engineering, project management, and business processes is a common response to a recurring problem that is usually ineffective and risks being highly counterproductive. The term, coined in 1995 by computer programmer Andrew Koenig (programmer), Andrew Koenig, was inspired by the book ''Design Patterns (book), Design Patterns'' (which highlights a number of design patterns in software development that its authors considered to be highly reliable and effective) and first published in his article in the ''Journal of Object-Oriented Programming''. A further paper in 1996 presented by Michael Ackroyd at the Object World West Conference also documented anti-patterns. It was, however, the 1998 book ''AntiPatterns'' that both popularized the idea and extended its scope beyond the field of software design to include software architecture and project management. Other authors have extended it further since to encompass environmental/organizational/cultural anti-pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
