Software Development and Management Questions

Multiple choice

Which of the following is NOT desired in a good Software Requirement Specifications (SRS) document?

  1. Functional Requirements

  2. Non Functional Requirements

  3. Goals of Implementation

  4. Algorithms for Software Implementation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An SRS document specifies WHAT the software should do (functional requirements, non-functional requirements, and implementation goals), not HOW to implement it. Algorithms and implementation details belong in design documents, not requirements specifications. Mixing implementation details with requirements reduces flexibility and constrains design choices unnecessarily.

Multiple choice

A company needs to develop digital signal processing software for one of its newest inventions. The software is expected to have 40000 lines of code. The company needs to determine the effort in person-months needed to develop this software using the basic COCOMO model. The multiplicative factor for this model is given as 2.8 for the software development on embedded systems, while the exponentiation factor is given as 1.20. What is the estimated effort in person-months?

  1. 234.25

  2. 932.50

  3. 287.80

  4. 122.40

A Correct answer
Explanation

Effort person per month = $\alpha.$(kDSI)B KDSI = kilo LOC = 2.8×(40)1.20 = 2.8×83.6511 = 234.22 person per month

Multiple choice

A company needs to develop a strategy for software product development for which it has a choice of two programming languages L1 and L2. The number of lines of code (LOC) developed using L2 is estimated to be twice the LOC developed with L1. The product will have to be maintained for five years. Various parameters for the company are given in the table below.

Parameter Language L1 Language L2
Man years needed for development LOC/10000 LOC/10000
Development Cost per year Rs. 10,00,000 Rs. 7,50,000
Maintenance time 5 years 5 years
Cost of maintenance per year Rs. 1,00,000 Rs. 50,000

Total cost of the project includes cost of development and maintenance. What is the LOC for L1 for which the cost of the project using L1 is equal to the cost of the project using L2?

  1. 4000

  2. 5000

  3. 4333

  4. 4667
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

LOC L1 = x 2 L = 2x Total cost of project $\dfrac{x}{10000}\times1000000 + 5 \times 100000 = \dfrac{2x}{10000}\times750000+50000\times5$ 100x + 500000 = 150x + 250000 $\Rightarrow$50x = 500000 – 250000 $\therefore$        $x = \dfrac{250000}{50} \Rightarrow x = 5000$

Multiple choice

Why is it necessary to perform feasibility study before developing a system?

  1. It lets the developer analyse the proper resources required to develop the system.

  2. It lets the developer estimate the proper time or deadline for the system.

  3. It lets the developer check the economic status of the system.

  4. All of the above

  5. Feasibility study bears no relationship with project development.

D Correct answer
Explanation

Feasibility study is of various types such as technical, economical, operational, legal, etc. and all are required if you wish to complete the project successfully.
