Best Practices and the Sdlc
It has long been accepted that constant change is fundamental to IT. While most IT managers understand that change is part of the norm, the organizations that employ them often resist it. Successful IT development calls for having a clear blueprint for proper IT direction of an organization. By using a System Development Life Cycle (SDLC) model and sound best practice methods, an IT manager can define that blueprint and make the best possible IT decisions.
According to http://www.bigpedia.comthe SDLC relates to models or methodologies that people use to develop systems, generally computer systems. A number of SDLC models have been created: waterfall, fountain, spiral, build and fix, and rapid prototyping. There is not a definitive correct model, but most models will include the following steps or at least a variation. The first step is the projects planning stage, in this stage the project manager (PM) decides which SDLC model to use. The PM will also survey and gather information in regards to the current team’s skill and experience, any concerns or issues perceived by upper management, such as cost, and a process for following up the work agreement. The next step is the analysis of the system. During the system analysis the PM breaks down the entire project in to small pieces and assigns each department their applicable tasks. This step is where the plan is finalized and the PM begins to move onto the systems design. Understanding the systems design is essential to developing the system. At this step, each department head devises a plan on how their section can help develop the system. In the third step, the architectural design, these individual plans are spliced together to form the completed plan. Also during this step the work of building the system takes place. The PM’s focus shifts from planning the project to managing the development of the project. During the next step, the testing of the system takes place. This will ensure that all the bugs and
