In the process of software development there are more steps in the outside of the coding environment. The importance of this statement is that software development depends of the flow of the project itself. This means that there most be iterations between phases of the process so that there is feedback and adaptation. With these steps being unified means that software development will be the same or at least with the same essence here and there.
The difference between the life cycles of software and the USP ( Unified Software Process ) is that one stays in the boundaries of coding and analysis, while the USP also takes action in the business of the development. This is a key topic inside the USP, because is the connection between the three main factors of the purpose of software. These three pillars are the business people, the developer team, and the final client.
To explain more about the USP’s, I will put in focus one of the most useful models out there which is the RUP ( Rational Unified Process ).
The RUP is a software development process from Rational Software, which is a division of IBM. The main focus of this model is to include four main phases in the unified process. When analysing these steps one can consider the three pillars that were explained before, and that’s because the flow of the process takes care of all of them with the analysis, design, implementation, testing, and deployment.
- Inception: This is the first phase of the RUP model. Here is where the connection with the business area is established, and that is because the idea for the project is created and discussed. The resources of the project are determine also here.
- Elaboration: The second phase of the RUP, where the connection between the business are and the developers is established. This phase is key in the development using this model because of the applications that will be used in the development and also the usage of resources throughout the process.
- Construction: This phase is part of the developers only because is where the project is designed, written and tested. Once it is completed, the project goes to the last phase.
- Transition: In this last phase the pillar of the client is invoked, and with the public release of the product there are some adjustments and final updates from the clients feedback.
The main essence of a unified software process is the conjunction of all the pillars in the company working together. Each one of those pillars has an important participation and makes the process of developing quite structured and precise for excellent quality. I personally recommend following these steps when a software project is made, not only because of the accurate steps to follow but also because of the success that can be made after trying it out.
There is nothing permanent except change.
