System Development Life Cycle in Seven Phases
As a computer software engineer, you need to know the system development life cycle and how it impacts any given project. The process is in place to provide a structured way to develop a quality system with a proven framework to meet or exceed a particular expectation. There are seven phases in the system development life cycle, and we will highlight each of them here for better understanding.
As with virtually all software engineering projects, you have to first find the problem so you can work toward a solution. This is the first step in the system development life cycle. Consider all the time and resources you’ll need to complete the project, so proper expectations can be set and goals can be created.
Once your plans are developed, it’s important to analyze the system and how it will help the end user. This is a point where you can identify flaws and communicate with the end user to determine what aspects are helpful or unhelpful, so you can meet their needs as closely as possible.
Designing a new system is one of the most detailed aspects of being a computer software engineer. This phase involves heavy details regarding features, specifications and operations which will determine how the system will work, and what you will do to make it work throughout the development.
The development phase is when production begins for a computer software engineer. The wheels will start moving at this phase, and following the planning, analysis and design phases will help development move forward most efficiently.
As with any software engineering projects, the testing phase is arguably the most important. You not only have to test to ensure the system has been integrated properly, but to also evaluate and ensure the system meets all the needs of the end user.
This is the phase where the new system gets rolled out into production. Transferring files and data from the old system to the new system begins happening at this point, and needs to be monitored closely at all times.
Once the implementation phase has completed, a full evaluation should be completed by the end user. Once evaluated, the role of a computer software engineer is to fine-tune the system to meet specific needs of the end user. There will always be certain features added, removed or changed at this phase, which is important to ensure the complete satisfaction of the system.
