Q1.
Waterfall Model, V-Model and Spiral Model are of the software development
processes. Companies are using these models to have a systematic and defined
approach in software development. Which of the four phases are involved in the
software development process?
(Listing
the 4 types- 4 marks, explaining the types- 4 marks, examples-2 marks) (7 10 marks)
Answer.
Listing
the phases of SDLC
Software life cycle models describe
phases of the software cycle and the order in which those phases are executed.
Each phase produces deliverables required by the next phase in the life cycle.
Requirements are translated into design. Code is produced according to the
design which is called development phase. After coding and development
the testing verifies the
Q.2.
Software estimation is the first phase of project planning and it is the
process of judging a software product and solving the problem associated with
the software project. We follow some important steps to achieve reliable cost
and effort estimates. Explain the different estimation models and estimation
techniques. ( a. Explaining different estimation models, b. Explaining
estimation techniques) 6,4
ANS:
a)
Estimation models
As, software has
become very expensive, large cost estimation errors will make a huge
difference between profit and loss and hence software estimation plays
an important role in a software project management activity. The
different estimation models involved in a software project are:
Q3.
a. You are a SCM manager in a software company. How will you establish a
software configuration management process in a company?
(Definition-
1 marks, 4 procedures in software configuration management process-4 marks)
Answer.
Definition: SCM identifies,
controls, audits, and reports modifications that invariably occur while
software is being developed, and after it has been released to a customer.
Software Configuration Management Process
Software configuration
management is an important element of software quality assurance. Its primary
responsibility is the

a.
Unit testing
b.
System testing
c.
Debugging
d.
Verification and validation
ANS:
a)
Unit Testing
To understand unit testing,
let us first understand ‘what is a unit?’ The smallest building blocks
of software are called as units. Units are made up of individual
functions in a language like C. We can define ‘unit testing’ as the
method of validating small basic blocks of a complicated system, prior
to testing of an integrated big module or the whole system.
Q6.
What are the different methods of software prototypes and tools? (definition of software prototype-1 mark, 3
types of techniques- 3 marks, explaining tools- 4 marks, benefits of software
prototype- 2 marks) 10 marks
Answer.
Software
prototype:
Software
prototyping,
refers to the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. It is an activity that can occur insoftware development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing.
