(ii) Discuss about unplanned communication and its events in detail. (8)
12. (a)(i) How do you identify Actors and scenarios in a project? Explain. (8)

13. (a)(i) What is coupling and cohesion in system design? Also explain how to reduce the coupling of subsystems. (8)
(ii) Assume you are developing a system that stores its data on a Unix file system. You anticipate that you will port future versions of the system to other operating systems that provide different file system. Propose a subsystem decomposition that anticipates this change. (8)

(Or)

(b)(i) Discuss mapping of subsystems to processors and components. (8)
(ii) How is communication difficult in system design? Explain. (8)
14. (a)(i) How do you plan for testing? Explain with PERT chart. (8)

(1) A project involves a number of participants.
(2) Participants can take part in a project either as project manager, team leader or developer.

(Or)

(b)(i) How do you identify the missing attributes and operations in interface specification? Explain. (8)
(ii) What is Unit testing? Why it is important in software project? Explain. (8)
