- Explain the advantages and disadvantages of each model, as well as the step(s) that you feel should be added or deleted to improve the effectiveness of each model.This paper compares and contrasts three different techniques for establishing system requirements throughout the analytical process. Consider the following questions: When do you believe each of the methods you compared would be most helpful, and what are the disadvantages of each of the techniques you examined?Define prospective problems while you create the framework, then consider potential obstacles as you implement your solutions. Either way. Is this significant or not?
- Explain • Vision • Definition • Development • Maintenance During SDLC with any simple example.Systems Development Life Cycle: Objectives and Requirements Source: http://www.benderrbt.com/Bender-SDLC.pdf A systems development lifecycle (SDLC) has three primary objectives: ensure that high quality systems are delivered, provide strong management controls over the projects, and maximise the productivity of the systems staff. In order to meet these objectives, the SDLC has many specific requirements it must meet, including: being able to support projects and systems of various scopes and types, supporting all of the technical activities, supporting all of the management activities, being highly usable, and providing guidance on how to install it. The management activities include: setting priorities, defining objectives, project tracking and status reporting, change control, risk assessment, step wise commitment, cost/benefit analysis, user interaction, managing vendors, post implementation reviews, and quality assurance reviews. In order to meet all of the SDLC's objectives and…Maintaining traceability during requirements and subsequent activities is expensive, because of the addition information that must be captured and maintained. The followings four are the benefits of traceability that outweigh this overhead. 1 Ability to show that all requirements have been implemented. 2 Ability to show that all features in the system correspond to a requirement. 3 Ability to assess the impact of a change. 4 Ability to track the human source of a requirement. Which of those benefits are directly beneficial to the analyst? Please write number (or numbers) which, you think, is (or are) beneficial to the analyst.
