Question
- Choose a system of your own choice, evaluate it, and identify the limitations in terms of meeting the various users’ needs. Perform a PACT Analysis to identify the various group of people who could use the system, then resign the chosen interface to meet the needs of all these class of people you identify. Thus, you are presenting the old interface and your own designed interface. With a written document of improvements, you introduced.

Present the pattern in outline form using two illustrative examples, and then implement it in code to verify that it really works.arrow_forwardEvaluate three system requirement definition methods: classic, contemporary, and radical. When should you apply each of the tactics you compared? Which methods have drawbacks? Which one would you pick?arrow_forwardGive reasons why deep access is preferable to shallow access from the standpoint of a developer, rather than just making a performance-based argument for it.arrow_forward
