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 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 deliverable of the implementation phase against requirements.

There are following six phases in every Software development life cycle model:

 

  • Requirement gathering and analysis
  • Design
  • Implementation or coding and testing

 

 

  1. 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: The term refers to a process of writing and maintaining the source code, but in a broader sense of the term it includes all that is involved between the conception of the desired software through to the final manifestation of the software, ideally in a planned and structured process. Software development is the computer programming, documenting, and testing involved in creating and maintaining applications and frameworks involved in a software release life cycle and resulting in a software product. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products

 

Different estimation models:

 

 

 

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 so that a system maintains its integrity over time. CM implements the policies, procedures, techniques, and tools that are required to manage, evaluate proposed changes, track the status of changes, and to maintain an inventory of system and support documents as the system changes. CM programs and plans provide technical and administrative direction to the development and implementation the procedures, functions, services,

 

 

 

  1. 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 internally in a company or organization doing software development. Typically bug tracking systems are integrated with other software project management applications. Having a bug tracking system is extremely valuable in software development, and they are used extensively by companies developing software products. Consistent use of a bug or issue tracking system is considered one of the “hallmarks of a good software team”

Details of bug fixation cycle :

The main benefit of a bug-tracking system is to provide a clear centralized overview of development requests (including both bugs and improvements, the boundary is often fuzzy), and their state. The prioritized list of pending items (often called backlog) provides valuable inp

 

 

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

  1. Define main users goals
  2. Define system usage patterns
  3. Invent functional solutions to meet users and usage patterns
  4. Define main navigation paths
  5. Create UI mock ups
  6. Polish UI Elements
  7. Identify System Users :

This is the most important question. If you miss with users, you will build the wrong solution. All further analyses will relay on defined user roles, so be very careful with

 

 

 

  1. 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 (test descriptions) are produced which create a building block for generating a full conformance test suite for the standard.

During the process of producing the test assertions and performing the specification review, UniSoft will highlight the following:

specification inconsistencies

 

 

Q.5 Write short note on

 

  1. Unit testing
  2. System testing
  3. Debugging
  4. Verification and validation

 

Ans:  a. Unit testing: In computer programming, unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures are tested to determine if they are fit for use. Intuitively, one can view a unit as the smallest testable part of an application. In procedural programming, a unit could be an entire module, but it is more commonly an individual function or procedure. In object-oriented programming, a unit is often an entire interface, such as

 

  1. 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 or logic

System testing of

 

 

  1. 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

 

 

  1. 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 that it fulfills its intended purpose.

 

 

 

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 entire layer of the design at the same time. This type of prototyping is most common with large
