Performance is measured by the useful work completed or done by a system. Performance is related to well-planned and organized processes and proper design.
What type of requirement is performance? Select one.
Question 2 options:
A
Functional Requirement
B
Nonfunctional Requirement
What difficulties are associated with system analysis?What variables contribute to deciding if a system has a high probability of success or whether it is not feasible?What factors contribute to system project failure?
As part of the analytical process, this study evaluates and contrasts three distinct methods for creating system requirements. Think about the following issues: What are the pros and drawbacks of each of the strategies you examined? When do you think each of the methods you evaluated would be most useful?
