software development life cycle (sdlc) is a process used by the software industry to design, develop and test high quality softwares. it aims to be the standard that defines all the tasks required for developing and maintaining software. the life cycle defines a methodology for improving the quality of software and the overall development process. planning for the quality assurance requirements and identification of the risks associated with the project is also done in the planning stage. this is done through an srs (software requirement specification) document which consists of all the product requirements to be designed and developed during the project life cycle. based on the requirements specified in srs, usually more than one design approach for the product architecture is proposed and documented in a dds – design document specification.
in this stage of sdlc the actual development starts and the product is built. if the design is performed in a detailed and organized manner, code generation can be accomplished without much hassle. the programming language is chosen with respect to the type of software being developed. once the product is tested and ready to be deployed it is released formally in the appropriate market. then based on the feedback, the product may be released as it is or with suggested enhancements in the targeting market segment. each process model follows a series of steps unique to its type to ensure success in the process of software development.
sdlc is a way to measure and improve the development process. this helps to reduce waste and increase the efficiency of the development process. defining requirements is considered part of planning to determine what the application is supposed to do and its requirements. a prototype is like one of the early versions of software in the iterative software development model. documentation can be a formal process, including wiring a user guide for the application. even companies that strive to create software that’s easy and intuitive benefit from the documentation.
this can be as simple as a payment portal and download link on the company website. one advantage of the waterfall model is each phase can be evaluated for continuity and feasibility before moving on. this solves much of the problems of older applications that were arcane and cumbersome to use. like agile, this seeks to improve the usability and relevance of applications. in addition to the models and stages of software development, there are a few other helpful practices. a software development cycle management system works to control and manage each step of the development cycle. like many business processes, sdlc aims to analyze and improve the process of creating software.
