How The System Development Life Cycle Works For Creating Custom Business Software

Posted on: 26 January 2018

If your business needs to hire a software engineer to create custom software for your business, it is important to understand how the system development lifecycle works for creating original software. Understanding how the system development lifecycle works will allow you to communicate more effectively with the software engineer you hire, and will allow you to better understand the development process.

Project Planning

The first phase determines what exactly the project is that the software engineer team will be working on. During this phase, the main purpose of the software, as well as the primary goals and objective of the software, are established. This is the big picture phase of creating custom software for your business.

System Analysis

The second phase of developing software is focused on getting into the specifics of the project. The goals set in the first phase are turned into software functions and operations, and the end-results that the software needs to accomplish are more firmly defined and determined.

System Design

The third phase is the most in-depth planning phase, where all of the features and operations are determined and written out in detail. This includes designing high-level functions and tasks such as the pseudocode, process diagrams, rules and layouts for the software program.


This is where the planning turns into action. During the implementation phase, all of the actual code for the program is written. The better the planning phase goes, the more focused and faster the implementation stage can move.


Once the program is written, it needs to be tested. The different elements of the program are brought together one by one,  and tested at each stage. Bugs and glitches often show up when different elements of the program are put together; the software development team will make sure that they are all fixed before releasing the program.


Once the software program has been created, tested and perfected, it is time to roll out the software program within your company. You can start using the software program now for your business needs.


Finally, just because the software has been deployed doesn't mean that the creation process is done. The last phase is the maintenance phase, where the software development team checks in with you to make changes and additions to the software that will make it more effective for your business and ensure that the software continues to work with continuously evolving computing platforms.

If you need some custom software developed for your business, like process engineering software, then understanding the basic flow of creating software can help you better communicate and work with the software development team you hire.
