First Semester 2013-2014
Comprehensive Examination (EC-3 Regular)
Course No. : SS ZG562 Course Title : SOFTWARE ENGINEERING &
MANAGEMENT Nature of Exam : Open Book Weightage : 50% Duration : 3
Hours Date of Exam : 09/11/2013 (AN) Note: 1. Please follow all the
Instructions to Candidates given on the cover page of the answer
book.2. All parts of a question should be answered consecutively.
Each answer should start from a fresh page. 3. Assumptions made if
any, should be stated clearly at the beginning of your answer.
Q.1. Indicate if the following statements are true or false.
Support your response with brief justification. No credit given for
responses without justification.
(a) Software coupling is a sign of poor architectural design and
can be avoided using good practices.(b) As per Polya, software
engineering practice can be described as understand the problem,
plan a solution, carry out the plan, and deploy solution.(c)
Analysis patterns are discovered, they are not explicitly
created.(d) Drivers and stubs are not needed for unit testing
because the modules are tested independently of one another.(e)
With thorough testing it is possible to remove all defects from a
program prior to delivery to the customer.(f) Equivalence testing
divides the input domain into classes of data from which test cases
can be derived to reduce the total number of test cases that must
be developed.(g) A successful test is one that proves program is
bug-free.(h) Software quality and functionality must be measured
indirectly.(i) A software quality metric that can be used at both
the process and project levels is defect removal efficiency.(j)
Function points are of no use in developing estimates for
object-oriented software. [1 X 10 = 10]
Provide concise point-wise answers
Q.2. List considerations to be made in choosing an agile process
vs. prescriptive process. [5]
Q.3. Prepare assignment letter for a Systems Analyst, listing 10
responsibilities. [5]Q.4. For a university library system, identify
analysis classes with justification. Draw CRC
diagram for one of the classes. [3 + 2 = 5]
Q.5. Explain component based software engineering highlighting
its differences with ground-up (conventional) software engineering.

Q.6. A mason is employed to lay a brick wall of 10m length. Raw
materials cost Rs 10000/- per meter and labor cost is Rs 1000/- per
day. Raw material is procured on JIT(just-in-time) basis. The work
is to be done in 10days. By the end of 5 th day, 4m of wall is
laid. Calculate EV, CV, SV, CPI, and SPI. Based on results suggest
management response.
[4 + 1 = 5]
Q.7. List and explain various aspects of software complexity.
Propose software engineering responses to software complexity.
[5]
Q.8. A software application to be developed using
object-oriented paradigm, has 3 loosely coupled subsystems S1, S2,
S3. Analyst identified 3,4,6 key classes for the subsystems
respectively. While S1 and S2 require complex GUI, S3 requires no
user interface. Assuming 15 days development effort per class and
Rs 3000/- developer cost per day, estimate cost of development.
State any assumptions made. [5]
Q.9. Provide brief responses:(a) Differentiate white-box testing
and black-box testing with example test cases.
[1 + 2 = 3] (b) Derive no of execution paths in a program
containing if...then...else statement within a loop to be executed
10 times. [2]
