Software Management MCQs

73. The expected value for the estimation variable (size), S, can be computed as a weighted average of the optimistic(Sopt), most likely (Sm), and pessimistic (Spess) estimates given as___________________?

by
A. EV = (Sopt + 4Sm + Spess)/4
B. EV = (Sopt + 4Sm + Spess)/6
C. EV = (Sopt + 2Sm + Spess)/6
D. EV = (Sopt + 2Sm + Spess)/4
✅ The correct answer is option B.
Explanation: This assumes that there is a very small probability that the actual size result will fall outside the optimistic or pessimistic values.

79. Which of the following is the reason that software is delivered late ?

by
A. Changing customer requirements that are not reflected in schedule changes
B. Technical difficulties that could not have been foreseen in advance
C. Human difficulties that could not have been foreseen in advance
D. All of the mentioned
✅ The correct answer is option D.

80. Which of the following uses empirically derived formulas to predict effort as a function of LOC or FP ?

by
A. FP-Based Estimation
B. Process-Based Estimation
C. COCOMO
D. Both FP-Based Estimation and COCOMO
✅ The correct answer is option D.
Explanation: Function points and COCOMO are used to evaluate effort.
