Justification and need for full system testing must be made clear.
Q1.A scenario is a statement of assumptions about the operating environment of a particular system at a given time; that is, it is a narrative description of the decision-situation setting. What does a scenario describe, and what may it provide?
Q2.According to Simon (1977), most human decision making, whether organizational or individual, involves a willingness to settle for a satisfactory solution, "something less than the best." This is called satisficing. How does a decision maker go about satisficing?
In software configuration management process, changes are reviewed, approved (or rejected), controlled, and tracked. There is a heavy focus on requiring that all changes must be reviewed and only permitted and being authorized by the Change Control Board (CCB).
Justify FOUR (4) arguments on how a properly implemented change management process can enable a greater volume of useful change?
