What are the Software Development Life Cycle?


There are various applications development procedures defined and designed that are used/employed during the development process of applications, these approaches are also called”Software Development Process Models” (e.g. Waterfall model, incremental version, V-model, iterative model, RAD model, Agile model, Spiral model, Prototype version, etc.). Each procedure model follows a particular life cycle to guarantee achievement in process of software development.

Software life cycle models describe phases of the software cycle and also the sequence in which those phases are executed. Each stage produces deliverables required by the next phase in the life cycle.

Requirements are translated into style. The code is produced in line with the design which is known as the development stage.

After coding and development, the testing verifies the deliverable of this execution phase contrary requirements. The testing team follows the Software Testing Life Cycle (STLC) which is similar to the growth cycle followed by the development team.

You will find the following six phases in each Software development life cycle model:


What is software development

  1. Requirement gathering and analysis
  2. Design
  3. Implementation or coding
  4. Testing
  5. Deployment



1) Requirement gathering and analysis:

Business requirements are accumulated in this stage. This phase is the main focus of the project managers and stakeholders. Meetings with managers, stakeholders, and users are held to be able to ascertain the requirements such as; Who is going to use the machine? How can they use the system? What data should be input into the system? What information ought to be output by the system? These are general questions that get answered through the requirements gathering phase. After necessity gathering, these requirements are examined for their validity and the prospect of integrating the requirements from the system to be growth is also examined.

At length, a Requirement Specification document is created which serves the purpose of principle for another phase of this model. The testing team follows the Software Testing Life Cycle and starts the Exam Planning phase following the analysis of the demand is finished.

2) Design:

In this phase, the system and software design is ready from the requirement specifications that were studied in the first stage. System Design helps in establishing system and hardware requirements and also helps in specifying overall system architecture. The system design specifications function as input for another phase of the design.

Within this phase, the testers come up with the Evaluation strategy, where they cite the best way to test, the way to test.

3) Implementation / Coding:

On getting system design files, the work is divided into modules/units and actual coding is started. Since in this phase, the code is created so it is the main focus for the developer. This is the most rapid period of the program development life cycle.

4) Testing:

After the code is developed it’s tested against the prerequisites to make sure that the item is actually solving the demands addressed and accumulated during the requirements phase. In this phase all types of operational testing such as unit testing, integration testing, system testing, approval testing are completed in addition to non-functional testing are also done.

5) Deployment:

After successful testing, the item is sent/deployed to the client for their usage.

As soon as the item is provided to the clients they will first do the beta testing. If any changes are required or if any bugs have been captured, then they are going to report it to the engineering team. Once those changes are made or the bugs are fixed then the last installation will take place.
