Assume that you are the project leader for the library book collection management system that you have been developing the system over the several months. However, as you review the current set of models, you realize that even though the models provide a rather complete description of the problem-domain layer, the evolving models have begun to become unmanageable. As project leader, you also need to guarantee that the design will be efficient.

Q2) As a system analyst, discuss with your development team the key points that you consider them as critical points for optimizing the design before jumping into coding phase.
