Web 2.0 technologies, including wikis, inherently support change. This flexibility is expressed in a wiki's ability to support continually changing knowledge and content using a collaborative approach. This support of changes is also supported by the fact that most wikis have been built using an open architecture that makes it easy to extend a wiki technology in unanticipated ways. Many wikis have a vibrant ecosystem of third-party developers providing robust high-value extensions.
The platform agility provided by most wikis is one of its key selling points. New requirements are easy to accommodate. Typically wiki functionality can be extended for a variety of purposes . However, a platform can only be as agile as the set of SDLC (software development life cycle) processes used by the group responsible for maintaining wiki platform changes. Agile delivery practices such as those discussed by XP, SCRUM, etc. are ideal when structuring and managing the continual set of changes often required to make any wiki platform successful over the long term.
There are three points to consider in relationship to this pattern.
