About Software Development Life Cycle (SDLC)

●      Software Development Life Cycle (SDLC) is a process to design, develop and test high-quality software.

●      SDLC helps to build software applications.

●      It is the framework, which defines the tasks performed at each step in the development process from planning to maintenance.

●      The aim of SDLC is to produce software that meets the expectations and demands.

 

Why SDLC is used:-

●      System development life cycle (SDLC) is used to develop IT projects.

●      Its purpose is to deliver high quality products as per the requirement.

●      It is used to lower the cost of software development which improves the product quality.

●      It is used to control and track the projects easier.

●      It is used to identify the project's risks at the early stage.


Advantages of SDLC:-

●      SDLC is very simple to understand and easy to use.

●      SDLC can improve the development speed.

●      It reduces the project risks.

●      All the team members can have a clear project development plan.

●      It is easy to track and control the projects.

 

Disadvantages of SDLC:- 

●      It increases the development cost and time.

●      It is an outdated process.

●      Before starting any project, it should be clear with the exact requirement.

●      It is not suitable for long-term projects.

●      There is a lack of flexibility. 


Phases of Software Development Life Cycle:-

●      The Software Development Life Cycle process consists of various phases to work in a smooth and productive way.

●      The multiple phases of SDLC involve planning, coding, building, testing, releasing, deploying, operating, and monitoring.

●      The following diagram shows the various stages of the typical SDLC process.


Explanation of phases:-

 

Planning Phase:-

●      This is the initial stage of the SDLC process. It includes calculating the cost, to create the project target goals, and can create the project structure.

●      This planning phase includes the project requirements and the purpose.

●      During this planning phase, team members will discuss how they can implement the project successfully without risks.


Coding phase:-

●      This coding phase includes the actual code of the project.

●      At this phase, the developer translates the software design into source code.

●      It includes code analysis and code review for multiple types of devices.


Building Phase:-

●      This building phase takes the code to build the software.

●      This is the phase where actual development starts.

●      At this phase, the programming code will be generated and the product is built.

●      Developers should follow the coding guidelines provided by the organization.

 

Testing Phase:-

●      This testing phase reduces the number of errors if the code is incorrect.

●      In this phase, the application can be tested before making it available in the market.

●      All types of tests can be performed at this stage.

●      This phase can be handled by the QA team to check any errors.

 

Release Phase:-

●      This release phase includes the team managing and deploying releases across all different environments.

●      It includes maintenance and support of the application which has to be developed.

●      This phase involves different environments like production, deployment and pre-production.

 

Deploy Phase:-

●      In this deployment phase, the application is officially released into the production environment or UAT.

●      UAT is the replica of the production environment.

●      The application can be available to the customers in this deployment phase.

●      This is the final stage where we can fix errors before releasing the application.


Operate Phase:-

●      In this operation phase, users can discover bugs that cannot be found during testing. These bugs can be resolved, which can be a new development cycle.

●      For every new release, a new development cycle can be launched.

●      At this phase, the development cycle is almost finished.

 
Monitor Phase :-

●      In this phase, various elements of  the application are monitored.

●      This includes the system performance, user experience, an analysis of errors or bugs in the system.

●      After the product is released in the market, its maintenance should be done for the existing user.

●      In this phase, it involves the updating and changing of the system.
