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.


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.


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


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.


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


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)

  • It involves proper plan and schedule.
  • Estimates the cost and budget.
  • It increases the development speed.
  • Provides a framework for the activities.
  • Project failure risks are decreased.
  • You can track and control the project development.
