TRADITIONAL SYSTEM LIFE CYCLE
The goal of the Traditional
System Life Cycle is to keep the project under control and assure that the
information system produced, satisfies the requirements. The traditional system
life cycle divides the project into a series of steps, each of which has
distinct deliverables, such as documents or computer programs. This is known as
the Systems Development Life Cycle (SDLC). The deliverables are related
because each subsequent step builds on the conclusions of previous steps. Some
deliverables are oriented toward the technical staff, whereas others are
directed toward or produced by users and mangers. The latter ensure that users
and their management are included in the system development process.
Although there is general
agreement about what needs to be done in the traditional system life cycle,
different authors name individual steps and deliverables differently. Many
versions of the traditional system life cycle emphasize the building or
software and de-emphasize what happens in the organization before and after
software development. Because this article is directed at business
professionals, its version of the traditional system life cycle emphasizes
implementation and operation in the organization in addition to software development.
