Software Development Life Cycle (SDLC)

SDLC (Software Development Life Cycle) : 

         A framework that describes the activities performed at each stage of a software development.

Six Stages of Software Development 

Life Cycle for Software Development

We have numerous types of SDLC models like Waterfall, Agile, Spiral etc. All this SDLC model must follow this 6 steps for developing errorless Software. Software Development Life cycle has totaled 6 Steps. All 6 steps are mentioned in below.

        1.Requirement Gathering and Analysis2.System Analysis3.System Design4.Coding5.Testing6.Implementation

1.) Requirement Gathering and Analysis

      Requirement gathering and analysis is the first stage and major stage of any SDLC model. This phase is basically the brainstorming phase because it has the many sub stages for like Feasibility Analysis Stages to check how much idea can put into action for development.

     In this Stages, communication taking place between stakeholders, end users and the project team. So, all the person which are related to the project and they gather information for software development.

    

       In that a brand new software development takes place more requirement gathering process for development and in other already build software not need too much information and data gathering process.

2.) System Analysis

       This is the second phase of SDLC where the entire system is defined in detail. In fact, In this stage Developer get a detailed blueprint of the various phases of the software that developed in the project.

       

       At this stage the system is divided into smaller parts to make it easier more manageable for the developers, designers, testers, project managers and other professionals who are going to work on the software in the latter stages.

3.) System Design

       In this phase the design of the system is designed. The Design is developed by The analysts and designers. The System analyst design the logical design for the designers and then designer get the basic idea of designing the software design of Front end and back end both.

       The system analyst and Designer work together in designing the software design and Designer design the best software design under the guidance of System Analyst.

4.) Coding

       It is the logical part of the development process. In this phase lots of brains are working for coding and get the final successful result for the software. In this A team of programmers is assigned by the company to work on the software.

       

       The work is subdivided under a sub-phase called Task Allocation, where each task is assigned different coder. So, the development process is working faster. 

5.) Testing

       By process of coding, then the final process testing is proceeding. When the software is ready it is sent to the testing department where Quality Analysts test it thoroughly for different errors by forming various test cases.

       Once the testing department and Quality Analyst makes sure that the software is error-free, then it goes to the next stage. So, the testing process is complete when all the testing module is complete.

6.) Implementation

       This is the final phase of the software development life cycle. In this stage, if the software runs on various systems by users or buyers. If it runs smoothly on these systems without any flaw, then it is considered ready to be launched.

       If it generates error then it goes to Testing Department for Testing and many coders write a new code for developers error-less Software.
