Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality software. The SDLC aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. SDLC refers to whole process of software development. It defines and describes, each and every phase that contributed towards the development of the software.
What is the need for SDLC? Software Development is a tedious and complex job. As such, standard guidelines and established framework works well to carry out the development process in an effectively organized manner, repeatedly for each unique software product. Segregates the process of development life-cycle into separate phases, for their independent and smooth implementation. And to minimize failures in a software project. There are six phases of Software Development Life Cycle in a subsequent manner:
Requirement Gathering and Analysis: This phase visions the gathering of business requirements, followed by the analysis to study and validate the feasibility of these requirements for implementation in the system. Client and Project Manager are the key persons in this phase.
Design: blueprint/software design is prepared, based on inputs, provided from the requirement gathering and analysis phase. This blueprint helps in determining the requirements, needed in the development of software such as hardware and system requirements. The outcome of this phase is software design.
Implementation: The software design is implemented in this phase through coding and programming. This phase generally involves modules and codes. This phase is developed or working software product that acts as an input for the next stage.
Testing: developed software is handed over to the testing team, to evaluate and validate the functioning of the software product, in accordance with its pre-defined requirements and meet the end users’ expectations.
Deployment: After getting through testing phase, successfully, software product is ready to get deployed on customer’s side for its use
Maintenance: Maintenance phase is all about resolving defects or issues, occurring on the customer’s side, while using the software product. It ensures the fixing of all issues post the deployment of software product at the customer’s site.
This is the main steps of software review, it is a standard practice that empowers organizations to follow systematic & well-defined approach, for carrying out the development in an effective way, so as to achieve desired software product of highest quality. I find this blog helpful to follow and make sure product is going to the direction. These steps need to apply to future product., as I have seen so many products got issues and have to call back.
