Q3. Explain the concepts of Function Points. Why FPs is becoming acceptable in industry?
Q4. The effort distribution for a 420 KLOC Semi-detached mode software development project is: product design 10%, detailed design 14%, code & unit test 26%, integrate and test 30%. How would the following change, from low to high, affect the phase distribution of effort and the total effort: analyst Capability, virtual machine experience, Programmer capability, and required language experience?
Q5 What do you understand by the term Software Development Life Cycle? Why is it important to adhere to a life cycle model while developing a large software system?
Q 6 List the five desirable characteristics of good SRS document
Q7. Enumerate the different types of coupling that might exist between two modules.

Q.1) Consider a project to develop a full screen editor. The major components identified are screen edit, command language interpreter, file input and output, cursor movement, screen movement. The sizes for these are estimated to be 4K, 2K, 1K, 2K and 3K delivered source lines. Use COCOMO Model to determine:
