Question

Identify considerations of primary importance in each step in the

Systems Development Life Cycle (SDLC) system .. Diagram the cycle and discuss its operation. I

Answer 1

The standard steps of SDLC or waterfall model are

• Requirement gathering
• Design the system
• Development of the system
• Testing the system
• Maintenance

Requirement gathering: This is the step where the project requirement are collected. The problems are defined and possible solutions are outlined. This is the beginning steps and the subsequent steps depend on the quality of requirement gather step.

Design the system: After the requirement is collected and frozen and before development can begin, the design of the system must be made. At this phase, the team creates an architectural overview. The next step of development is based on the design built at this stage.

Development: This is the development stage. This is usually the longest period and the solution is built at this stage. This process builds the solution for the problem defined at the requirement gathering phase.

Testing the system: At this phase, the development is complete and the testing is performed. Before the system goes live, the testing reveals bugs, flaws, drawbacks and other potential fixes that may be required. If necessary testing can result in triggering the development stage again.

Maintenance: At this stage, the solution is deployed and maintenance begins. Maintenance requires regular monitoring and checks. However, during maintenance there may be insights which triggers further problem and next iteration of development process.
