The Challenges of Retrofitting a Development Life Cycle

It is a rare company that does not have an existing system development life cycle. Your company may have purchased a method, or perhaps you built one from scratch. In either case, it is unusual to find that the method already provides a user-centered methodology. Perhaps someday every method will follow the user-centered paradigm, but as of today it is likely that the existing methodology is not user-centered.

Occasionally, a company needs a whole new development process. This scenario occurs not just within brand-new organizations—a new development process may also be needed when there is a major change in the technology or scope, such as the switch from simple Web brochures to complex Web application development. Usually, however, the organization already has a software development process and needs to deal with the relationship between the existing process and the newer user-centered design methodology. The methods have to be interwoven with proper communication and handoffs between the different types of development staff.
