SDLC (System Development Life Cycle) is a process of creating, altering information systems and the models and methodologies that people use to develop these systems. This process is quite popular among teams in IS project as it eases the process of building an IS system, it reduces system failures or its possibility of not meeting the end-users needs. Because there are so many members involved in the process of IS projects, it is not surprising that different goals and objectives can be seen by different people. SDLC comes into play here to organise certain phases and to allow proper communication between members. There are five phases:
This is the initial phase of any SDLC. Team roles such as leaders and managers are involved here. They identity a problem and plan a way in which why to solve it, and to see the feasibility of it. This is also the phase where teams and their roles are constructed. This is a vital phase for every team member to know their position and goal.
This is the phase where the role of system analysts becomes most prominent. Their task is to analyse what the problem is by asking questions such as why the problem exists, and what is the most feasible way to solve it. They study and collect data from old or other related systems and set out objects for the new system.
In this phase system designers have an important role in how they fulfil user requirements. Physical and logical design occurs here. It is also where system security is established and an implementation date is set here.
This is where the actual coding of the IS project takes place. Test runs occur here to spot any problems and to eliminate them. It is here where the system is finally implemented and team members are trained into understanding and fixing any problems with the system.
It is a common occurrence that bugs and flaws are seen within the system after it is implemented. It is in this phase therefore that the team role of maintenance occurs here to rectify any problems or update the system as they have been taught to do so.
