1. What are the different phases
of Software Engineering?
2. Define Software process model.
3. Why is requirements
elicitation process difficult?
4. What is the notation used by
functional modeling?
5. How is functional independence
measured?
6. When is transaction mapping
applied?
7. What are 'side effects' while
debugging?
8. When is orthogonal array
testing applicable?
9. Why LOC is not treated as a
standard metric?
10. What are baseline criteria in
SCM?
PART B — (5 × 16 = 80 Marks)
11. (a) (i) How are software
myths affecting software process? Explain with the help of examples. (Marks 2 +
6 = 8)
(ii) Discuss major areas of the
applications of the software. (Marks 8)
Or
(b) (i) Describe the role of
management in software development with the help of examples. (Marks 8)
(ii) How do 'Project risk'
factors affect the spiral model of software development? (Marks 8)
12. (a) What are prototyping
techniques? How are prototype models prepared for a software process? Discuss.
(Marks 3 + 3 +10)
Or
(b) Describe the structure of
software requirements specification documents explaining clearly the standards
to be followed. Write a typical SRS for bank transaction. (Marks 8 + 8)
13. (a) (i) What are the
characteristics of good design? Describe the different types of coupling and
cohesion. How is design evaluation performed? (Marks 3 + 4 + 3)
(ii) State the effects of
coupling and cohesion in software quality. (Marks 6)
Or
(b) (i) Why is UID critical for
highly interactive software? How is the real time software design performed for
a long term software project? (Marks 2 + 4 + 4)
(ii) Write down the software
design procedures for Data Acquisition and control system. (Marks 6)
14. (a) (i) Enumerate the various
types of software test. Which type of testing is suitable for boundary
condition? Justify. (Marks 2 + 6)
(ii) How do you relate software
testing results with reliability of the product? Explain. (Marks 8)
Or
(b) (i) Explain software
implementation techniques. What is the percentage in total cost of the project?
How do you expedite the implementation stage? (Marks 6 + 2)
(ii) What is meant by control
flow testing? ''Is it always falling with data flow testing in case of
software''? Justify.
15. (a) State the need for
software quality planning and control. How do you assess the process and
product quality of software? Write the quality assurance standards. (Marks 4 +
6 + 6)
Or
(b) Write short notes on:
(i) SCM. (Marks 4)
(ii) Software cyclomatic
complexity metric. (Marks 6)
(iii) Software cost estimation.
(Marks 6)
