SDLC creates a structure for the development process and teams in order to design, create and deliver the quality project by defining a number of activities, which need to be processed. The software development life cycle (SDLC) defines a methodology to improve the software quality and the overall development process.
As per my opinion, the methodologies of software development life cycle (SDLC) process can differ according to the working of the organizations. But the standards like ISO/IEC 12207 shows the processes, which develop a life cycle for software and also provides a standard to build and maintain the software. The intent of a Software development life cycle (SDLC) to produce a service or product, which is cost-effective, efficient and of high quality.
According to me, following are the phases of Software development life cycle (SDLC), which is followed to develop a high-quality product such as:
Requirement analysis: SDLC starts with this phase, where the requirement for the proposed system will be discussed with the associated stakeholder of the project. Further, Software requirement specification (SRS) is formulated as per the gathered data.
Design: In this phase, technical architects and developers begin the high-level design of the system and software to be able to deliver each and every requirement.
Implementation: In this phase, the coding operations are carried out as per the requirements by the developers or programmer.
Testing: During this phase, the experienced testers start to test the system against the proposed system requirements.
Deployment and Maintenance: Once the product is successfully developed as per the clients’ requirements, it is time to deploy the system, where the users can use the developed system in an effective manner.
