Software Development Life Cycle, SDLC for short, is a well-defined,
structured sequence of stages in software engineering to develop the
intended software product.
SDLC Activities
SDLC provides a series of steps to be followed to design and develop a software product efficiently. SDLC framework includes the following steps:
Communication
This is the first step where the user initiates the request for a desired software product. He contacts the service provider and tries to negotiate the terms. He submits his request to the service providing organization in writing.Requirement Gathering
This step onwards the software development team works to carry on the project. The team holds discussions with various stakeholders from problem domain and tries to bring out as much information as possible on their requirements. The requirements are contemplated and segregated into user requirements, system requirements and functional requirements. The requirements are collected using a number of practices as given -- studying the existing or obsolete system and software,
- conducting interviews of users and developers,
- referring to the database or
- collecting answers from the questionnaires.
