The Software Development Life Cycle is a process that is produces software with the highest quality and lowest cost in the shortest time. It is includes a detailed plan for how to develop, alter, maintain, and replace a software system. The SDLC aims to produce a high-quality software that is meets or exceeds customer expectations, reaches completion within the times and cost estimates. This is a process followed for a software project, within a software organization. It is consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. The life cycle defines a methodology for improving the quality of the software and the overall development process. It is starts with the analysis and definition phases, where the purpose of the software or system should be determined, the goals of what it a needs to accomplish need to be the established, and a set of definite requirements can be developed.
Then software construction or development stage, the actual engineering and writing of the application are completed. It is the software is designed and produced while attempting to accomplish all of the requirements that were set forth within the previous stage. There are the following six phases in every Software development life cycle: Requirement gathering /analysis, Design ,Implementation or coding, Testing, Deployment, Maintenance.That is,
Requirements Gathering/Analysis :- This phase is the critical to the success of the project. Expectations need to be the fleshed out in great detail and documented. This is an iterative process with much a communication taking in the place between stakeholders, end of the users and the project team.
Design :- Then this phase describes, in detail, the necessary specifications, features and operations that will be satisfy the functional requirements of the proposed system in which will be in place. Then this is the step for end users to the a discuss and determine their specific business information needs for the proposed system.
Implementation and Deployment :- This phase comes after the a complete understanding of system requirements and the specifications, it’s the actual construction the process after having a complete and the illustrated design for the requested system.
Testing :- This phase involves software integration and system testing normally carried out by a Quality Assurance the professional to determine if the proposed design the meets the initial set of business goals. The testing may be repeated, specifically to check for errors, bugs and interoperability. This is the testing will be performed until the end user finds it acceptable.
Maintenance :- In this last phase, periodic maintenance for the system will be carried out to make sure that the a system won’t become obsolete, this will be the include replacing the old hardware and a continuously evaluating system’s performance, it is also includes providing latest updates for the certain components to make sure it meets the right standards and the latest technologies to face current security threats. By the building the system in short iterations, we can the guarantee meeting the customer’s requirements before we build the whole system.
The Software development Life Cycle benefits of allow the highest level of management control and documentation.Then developers understand what they should build. All the parties agree on the goal upon front and see a clear plan for arriving at that goal. Everyone understands the costs and the resources required. The several pitfalls can turn an Software development life cycle is the implementation into more of a roadblock to the development than a tool that helps us. Failure to take into account the needs of customers and all users and stakeholders can result in a poor understanding of the system in requirements at the outset. The benefits of SDLC only exist if the plan is followed faithfully.For more
