The creation of this program is done through four main phase : planning phase‚ anylisis phase‚ design phase‚ and testing phase which is based on Software Development and Life Cycle (SDLC). The results from the testing phase of this program (verification and validation) demonstrates that the program can be run in accordance with its function and also the program can perform the calculation correctly.

System Development life cycle‚ (SDLC) is the development of custom information system for large IT projects. With the right information input on an organizations needs it will develop a system from start to finish. The phases of this process are‚ * System investigation‚ this is where professionals gather information on what problems a business may have‚ the software and programs that are needed‚ and what problems that may occur. * System analysis‚ this stage defines in detail the problem

Week 2 DQ DQ1 1. How were the problems with the system missed? Problems were missed by failing to complete the SDLC. The application was developed based on information gathered from agents‚ but doesn’t seem that it was modified during the system implementation phase. 2. How might these problems have been foreseen and possibly avoided? The problem could have been foreseen and possibly avoided by creating use cases. Use cases will help develop detailed requirements along with expectations‚ and
