Systems Development Life Cycle (SDLC)
Systems Development Life Cycle (SDLC) is a process used by organizations to develop and maintain information systems. It is a framework that defines the steps involved in the development, implementation, and maintenance of an information system. The SDLC process is used to ensure that all aspects of the system are properly planned, designed, implemented, tested, and maintained.
The SDLC process begins with the identification of a need for an information system. This need can be identified through market research or customer feedback. Once the need has been identified, the organization will then develop a plan for how to meet that need. This plan will include defining the scope of the project, setting goals and objectives for the project, and determining what resources will be needed to complete it.
Once the plan has been developed, it is time to begin designing the system. During this phase of the SDLC process, requirements are gathered from stakeholders and users in order to create a detailed design document that outlines how the system should function. This document will include diagrams and flowcharts that illustrate how data will flow through the system as well as any user interface elements that may be needed.
Once the design document has been completed, it is time to begin developing and implementing the system. During this phase of development, developers will create code based on the design document in order to bring it to life. Once all of the code has been written and tested, it can then be deployed into production environments where users can begin using it.
The next step in SDLC is testing and validation. During this phase of development, testers will use various techniques such as unit testing or integration testing in order to ensure that all components of the system are functioning correctly before they are released into production environments. Once all tests have been passed successfully, then it is time for deployment into production environments where users can begin using them on a daily basis.
The final step in SDLC is maintenance and support. During this phase of development, any issues or bugs found within production environments must be addressed quickly in order to ensure that users continue having a positive experience with their systems. Additionally, any changes or enhancements requested by stakeholders must also be addressed during this phase in order to keep up with changing business needs or customer demands over time.
Overall, SDLC provides organizations with an effective way to develop information systems while ensuring quality control throughout each stage of development from planning through maintenance and support phases afterwards. By following these steps throughout each stage of development organizations can ensure that their systems are properly planned out before they are implemented into production environments which helps reduce costs associated with rework or bug fixes later on down the line when they become more expensive problems than they would have been if caught earlier on during development stages instead.
