Software Development Life Cycle

Software Development Life Cycle (SDLC) is a process used to develop software. There are few phases in SDLC, In each phase a different process is done. SDLC makes a structure for the development team to design software efficiently. The main purpose of SDLC is to develop software or a product that is efficient and cost effective.

Phases of SDLC


The planning phase mainly focuses on required project planning work. Proper project planning is essential to build a successful project. An incomplete project planning and analysis are the main cause of project failure.  

During this phase of SDLC, the objective of the project is determined and the requirements to produce the product are considered as well as the project management plan, a budget plan that will lead to a successful project.


During this phase, the project team determines the end user requirements. This is done by taking help of the client, how the product will function, what are their criterias, how the finished product will function. The main aim of this analysis phase is to make sure that each of the requirements of the client gets fulfilled.


During this phase, the desired features and operations are described including all process diagrams, business rules, user interface and much other documentation.


After getting all the details from the previous phases the actual coding is done. This is the main phase for the developer as this is the time taking phase of SDLC.


After the development phase is done, all the pieces are framed together into a special testing environment, then the software is tested against the requirements to make sure that the software is solving all the needs of the client.


After the testing phase the product is delivered to the client, then the client will do beta testing first, if the client side finds any bugs or errors in the product then they will report the same to the engineering team, once all these are resolved the final deployment is done.


After the deployment, once the customer starts using the product then the actual problems arrive. It includes implementation of changes that the software might undergo over a period of time.

Software often needs to be upgraded or integrated with new systems the customer deploys. It is also needed to provide additional testing of software or version updates.
