The production and maintenance phase of systems development process entails:
The Systems Development Life Cycle (SDLC) was first developed in the 1960s to manage large software projects running on corporate mainframes. This approach to software development is structured and risk averse, designed to manage large projects that include multiple programmers and systems. It requires a clear, upfront understanding of what the software is supposed to do and is not amenable to design changes. This approach is roughly similar to an assembly line process, where it is clear to all stakeholders what the end product should do and that major changes are difficult and costly to implement. The following is the process of the SDLC. Various definitions of the SDLC methodology exist, but most contain the following phases. Show
The following table summarizes the important tasks in the stages of the SDLC and highlights the main deliverables from each task. The SDLC methodology is sometimes referred to as the waterfall methodology to represent how each step is a separate part of the process. Only when one step is completed can another step begin. After each step an organization must decide when to move to the next step. This methodology has been criticized for being quite rigid, allowing movement in only one direction, namely, forward in the cycle. For example, changes to the requirements are not allowed once the process has begun. No software is available until after the programming phase. Again, SDLC was developed for large, structured projects. Projects using SDLC can sometimes take months or years to complete. Because of its inflexibility and the availability of new programming techniques and tools, many other software development methodologies have been developed. Many of these retain some of the underlying concepts of SDLC, but are not as rigid. Other development approaches are explored in the next section What is maintenance phase in product development?The maintenance phase happens after the project team deploys the software and it's fully operational in the customer environment. During the maintenance phase, the customer monitors the software to ensure it continues to operate according to the coding specifications.
What are the stages in system development process?What are system development life cycle stages? Systems development life cycle phases include planning, system analysis, system design, development, implementation, integration and testing, and operations and maintenance.
What are the 5 phases of system development life cycle?The SDLC process includes planning, designing, developing, testing and deploying with ongoing maintenance to create and manage applications efficiently.
What is production phase in software development?Production Phase: In the Production phase, we mainly focus on the Implementation of Project and optimization including the reduced cost and risk factors of our project. It also involves various testing for efficient deployment of the project. It involves the large team size and most of the time it is predictable.
