Document Summary

10/25/16 4:10 pm: turn requirements into functional models, models are logical (independent of how they"re implemented. Abstract, should be high-level: develop use-cases from the requirements. Use case: how a system interacts w/its environment includes a diagram and description to depict discrete activities that the users perform fb: messenger, search bar, edit profile: develop activity diagrams from use-cases. Model business processes or how it operates illustrates movement of data b/w activities. Business process identification (bpi) with use-cases: don"t usually connect 2 actors to each other, use cases are commonly connected to 2 actors. Identifying major use-cases: review req. definition, id subject"s boundaries, id primary actors and their goals, id business processes and major use-cases, carefully review the current set of use-cases, split/combine some to create right size, id additional use-cases. Create a use-case diagram: place & draw the use-cases, place & draw the actors, draw the subject boundary, add the associations, example: library circulation system.
