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.
 the systems development life cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both.  the system development life cycle framework provides a sequence of activities for system designers and developers to follow.  the oldest of these, and the best known, is the waterfall model, a sequence of stages in which the output of each stage becomes the input for the next. each environment is aligned with different areas of the sdlc and is intended to have specific purposes. the object oriented approach views information system as a collection of objects that are integrated with each other to make a full and complete information system.
each of the sdlc phase objectives are described in this section with key deliverables, a description of recommended tasks, and a summary of related control objectives for effective management. control objectives help to provide a clear statement of the desired result or purpose and should be used throughout the entire sdlc process. the sdlc practice has advantages in traditional models of systems development that lends itself more to a structured environment.  at the completion of this stage, a development specification is produced that is sufficient to perform detailed design and development. system assessments are conducted in order to correct deficiencies and adapt the system for continued improvement.
software development life cycle (sdlc) is a process used by the software industry to design, develop and test high quality softwares. the sdlc aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. sdlc or the software development life cycle is a process that produces software with the highest in systems engineering, information systems and software engineering, the systems development life cycle (sdlc),, . in systems engineering, information systems and software engineering, the systems development life cycle, also referred to as the application development life-cycle, is a process for planning, creating, testing, and deploying an information system.
sdlc, or software development life cycle, is a set of steps used to create software applications. 1. planning stage in any software development project, planning comes first. 2. feasibility or what is sdlc? the software development lifecycle is a systematic process for building software that,
