GROUP A
1. According to COCOMO model which is the most fundamental attribute of a s/w product based on which size and effort is estimated. (ANS LOC)
2. To allocate resource to activities we use ______. (ANS Gantt chart).
3. Depiction of the interaction among object during certain period of time best defined a _____. (ANS sequence).
4. Which of the subsequent is not indicated in DFD???? (ANS timing)
5. Containment of fault _____. (ANS minimizes the cost to fix fault.)
6. Evolutionary model a few time is known as Successive & incremental.
7. DFD does not contain loops.
8. MS PROJECT 2000 is a/an case tool.
9. WBS is part of SPMP.
10. Gold plating is a risk item.
11. Linearly independent path is needed to compute the cyclometic complexity.
12. A text case should have a) data input, b) state of the system, c) data output.
13. Which of the subsequent can be used to relate DLOC to the effort & time needed to develop the s/w. (ANS Rayleigh Curve?????????)
14. To determine the reliability of a product rather discovering the fault is statistical.
15. Which CMM level focuses n project management? (ANS repeatable)

GROUP B
1. Explain how an s/w development effort is initiated and terminated in spiral model. What is egoless programming? 3+2
2. Explain when use PERT and GANTT? What is sliding window planning? 3+2
3. What are the various kinds of cohesion that may exist b/w 2 modules? What is a structure chart? 3+2
4. What is a stereo kind in UML? What is difference b/w sequence & collaboration diagram? 3+2
5. What do you mean by stub and driver module? What is stress testing? 3+2

GOURP C
1. A. what do you understand by the term structure programming? How modern programming languages like Pascal & c do facilitates structure programming? elaborate the advantages of structure programming? Vis a Vis unstructured programming. What a re the tree basic kinds of program construct necessary to develop a program for any provided program.
B. what is phase containment of errors? Difference ranging from incremental and RAID model?
2. a. what is difference ranging from revision and version of s/w product? What is change control and version control? How change & version control are achieved by using a configuration management tool?
B. coin toss issue for decision tree.
3. a. In the light of PNR curve show that maintenance phases requires about 60% of total resource, show from Putnam’s expression tat near compression of the schedule of s/w development project will make huge penalty in man power.
B. what is potential meaning of program? 14 unit operator ques..
4. a. Regression testing? How is performed?
b. Structural complexity of programming? describe a metric for measuring the structural complexity of program. How structural complexity of a program is various from its computational complexity?
C. design a black box test suit for a function called find_intersection takes four real number m1, c1, m2, c2 as arguments. Represent 2 straight lines
y=m1x + c1
y=m2x + c2
It determines the points of intersection of 2 lines depending on the values input to function. It displays any of the subsequent messages:
1. Single point intersection
2. Overlapping lines in time point of intersection
3. Parallel lines – no point of intersection
4. Invalid input values

5. a. elaborate the difference ranging from static and dynamic model in situation of OOmodel of system. Identify the respective UML diagram which provides these 2 models.
b. Draw a class diagram using UML to represent the fact that an order consist of 1 or more order item. every order item contains the name of item, its quantity, and date by which it needed. every ordered item is defined by an order item specification object having details such as vendor address, its unit price, and manufacturer.
c. How the data abstraction help in reducing the coupling in a design situation. explain the role of data dictionary in CASE environment.


6. Short note:
a. COCOMO II model
b. ISO 9000 standard.
C. function point
d. CASE tool
e. Mutation testing
F. work breakdown structure
