MMIS660 ASSIGNMENTS ASSIGNMENT-1 (Chapters 1, 2, 3) FOUNDATIONS FOR SYSTEMS DEVELOPMENT- 20% Chapter 1 1) List and explain the five major SDLC phases. The five major System Development life cycle are : Planning: is the architecture to find a solution to the business needs either to improve or to solve a problem. There are two main activities for this planning that is the formal in which is decided if the propose plan should be made in house of if the project should sent to outsource company. Analysis: the analysis phase is the study of the local resources. A study has to be made in case extra resources are needed with the changes. In example: what type of hardware, storage possibilities and tools to be used. This phase also studies the resources to comply with the new changes but mostly in descriptions. Design: this phase is divided in two: the logical this is where a comparison is hand on to test the alternatives for the new project and to make sure it works as intended. The physical design is where the tools are chosen to implement the new project in which includes aspects like Operating system, programming language and the type of database. Implementation: after the design phase is complete, the project is given to the programmer to start the development process as well as the testing, training and initial support. Maintenance: this is what I call the debugging and problem fixing phase. Updates are release according to customer complaints to tweak and repair bugs. 2) Describe how CASE is used to support each phase of the SDLC. As the name implies it, The Computer-Aided software engineer is a tool that facilitates the implementation of the system development life cycles: For planning: it diagram the information and system process and it is represented graphically For design: it displays and reports prototype to identify the requirements. For analysis: it performs a complete check on the implemented system
