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?

Answer : Four phases in software development process :

There are various software development approaches defined and designed which are used/employed during development process of software, these approaches are also referred as “Software Development Process Models” (e.g. Waterfall model, incremental model, V-model, iterative model, etc.). Each process model follows a particular life cycle in order to ensure success in process of software development.

Software life cycle models describe phases of

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.

Ans : Different estimation models:

There are many models for software estimation available and prevalent in the industry. Researchers have been working on formal estimation techniques since 1960. Early work in estimation which was typically based on regression analysis or mathematical models of other domains, work during 1970s and 1980s derived models from historical data of various software projects.

1. COCOMO :

Q3. a. You are a SCM manager in a software company. How will you establish a software configuration management process in a company?

Answer : Software configuration management process :

In software engineering, software configuration management (SCM) is the task of tracking and controlling changes in the software, part of the larger cross-discipline field of configuration management." SCM practices include revision control and the establishment of baselines. If something goes wrong, SCM can determine what was changed and who changed it. If a configuration is working well, SCM can determine how to replicate it across many hosts.

Procedure :

CM is the practice of handling changes systematically

b. You are appointed as a software developer in a software company and you have been asked by your project manager to check details of the bugs from the previous version. How will you gather details associated with the various bugs in the previous version?

Answer : A bug tracking system or defect tracking system is a software application that is designed to help keep track of reported software bugs in software development efforts. It may be regarded as a type of issue tracking system.

Many bug tracking systems, such as those used by most open source software projects, allow users to enter bug reports directly. Other systems are used only

Q4. a. If you are a software engineer you must be expert in the field of software, hardware and also database. It has been listed by the industry professionals that time and effort are the most important factors in the system analysis stage. Briefly explain the steps used in system analysis.

Answer : Steps used in system analysis :

1.Identify system users

2. Define main users goals

3. Define system usage patterns

4. Invent functional solutions to meet users and usage patterns

5. Define main navigation paths

b. If you are a software developer in small company, how will you conduct a specification review?

Answer : Conduction of specification review :

Writing software specifications is more complicated than one would initially suspect. The specification needs to be completely clear so that it can not be misinterpreted by an implementation or application developer in order to achieve full interoperability. UniSoft offers a specification review service to its' customers. This activity offers 1.two major benefits to the specification authoring body:

2.It provides a very thorough review of the specification.

3.A complete set of test assertions (

Q6. What are the different methods of software prototypes and tools?

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 in software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing.

A prototype typically simulates only a few aspects of, and may be completely different from, the final product.

Methods of software prototype :

1.Horizontal prototypes

The purpose of a horizontal prototype is to develop one

Q.5 Write short note on

a. Unit testing

b. System testing

c. Debugging

d. Verification and validation

Ans :  a. Unit testing :

Unit testing, also known as component testing, refers to tests that verify the functionality of a specific section of code, usually at the function level. In an object-oriented environment, this is usually at the class level, and the minimal unit tests include the constructors and destructors.

These types of tests are

b. System testing :

System testing of software or hardware is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code

c. Debugging :

Debugging is a methodical process of finding and reducing the number of bugs, or defects, in a computer program or a piece of electronic hardware, thus making it behave as expected. Debugging tends to be harder when various subsystems are tightly coupled, as changes in one may cause bugs to emerge in another. Many books have been

d. Verification and validation:

In software project management, software testing, and software engineering, verification and validation (V&V) is the process of checking that a software system meets specifications and

Q6. List and explain any 5 principles of design fundamentals.

Answer : Principles of design fundamental : Principles applied to the elements of design that bring them together into one design. How one applies these principles determines how successful a design may be. Good design, much like anything, starts with understanding the basics. Applying the following design principles will help us  avoid design disasters and allow you to communicate your key
