Stages of Software Development Life Cycle

What’re the SDLC Phases? Software Development Life Cycle, or SDLC is a process used to develop software. There are various stages or phases within the Software Development Life Cycle and in each stage, different activities occur.


SDLC produces a construction for the development groups to be able to design, generate and produce high quality applications by defining various tasks that need to happen The lifecycle defines a methodology for enhancing the quality of applications and the overall development process.

Thus, a typical software development lifecycle undergoes the following typical stages:

  1. Requirement Analysis

In this phase the demands for the job are defined by the Company Analysts. Hence, the group identifies why the application must be assembled, who will function as the system customers, what are the differences, how the new program can bridge the gaps, infrastructure requirements etc. By the end of this stage the functional specification files, gap analysis record etc. are developed.

  1. Design and Development

During this phase database modeling, applications structuring, interface layout, prototype improvement etc. requires place. By the end of the stage design documents which include the General Design Document (GDD)/Comprehensive Design Document (DDD) and also the codes are created.

  1. Quality Assurance and Testing

That is the stage for installing construct, system testing, bug fixing, User Acceptance Testing (UAT) and for preparing testing reviews. By the end of this phase a stable program with minimized malfunctions is ready for deployment.


  1. Execution and Deployment

During this stage trainings are conducted and the app is deployed at pilot sites initially followed by entire roll out. By the end of this period a completely operational, secure program is prepared to be used.

  1. Care and Support

During this span knowledge transfer, change requests, if any, impact analysis and all pending documentation is finished. At the end of this period, the vendor team hands over all the components of the job including codes, records and computer software licenses to the client.
