What is Software Development Life Cycle?

QA and Software Testing go hand in hand and are quite important for an enhanced and better quality application or software. Developing an application and Software is an extensive process. Software Development Life Cycle also known as SDLC is a Software Quality Assurance process which ensures the quality of the product built. It comprises of a detailed plan about the strategies to build the software. 

SDLC is divided into the phases mentioned below:

Requirement Analysis

This stage gives clarity about the project by gathering all the detailed client requirements. This is done by the developing team members and all the risks and opportunities are also assessed.

Feasibility Study

In this phase, the Software’s specifications, needs and requirements are documented.

Design

In this step, the design documents for the software are prepared as per the requirements and specifications and the overall architecture of the product is defined and modeled.

Coding

In this phase the developers start writing the codes with their preferred programming language.

Testing

Now after the coding is done, it is deployed for Software Product Testing where the product’s functionality is checked and any bugs or errors are identified. These are then communicated to the developers for rectification.

Installation

After all the system errors and bugs are dealt with, deployment process begins. Final product is then released and reviewed for deployment issues.

Maintenance

After the customers start using the application or software regular upgrades, bug fixings, addition of new features in the form of updates are regularly made.

Advantages of Software Development Life Cycle (SDLC)
