Traditional information system projects were developed using the Systems Development Life Cycle (SLDC) or ‘Waterfall Model’ to manage and implement the system. Designed in the 1960s this methodology sees the process split into a series of distinct steps:
Using the above ‘top-down’ process each step cannot commence until the preceding step has been completed and the findings passed down the chain, at each stage a review can take place to ensure that the requirements identified in the previous stage have been met. In recent years, this development process has come to be seen as too rigid, one of the major problems with this process is that the timescale involved from the project inception to the stage of implementation is far too long. Problems and delays at each stage of the process often result in late delivery of a system. However, a more serious problem is that because the development process is so long the final system produced can be out of date by the time it is released for use. As time passes, user requirements for a system may evolve as a company embraces new working process or technology, it is easy for these changes not to be incorporated into the system being developed and as a result, the completed system may not be fit for its intended purpose.
