Rational Unified Process: what you need to know

Rational Unified Process (RUP) is an agile software development methodology that divides the project lifecycle into four phases: inception, elaboration, construction, and transition. Each of them has its binding goals. And what is more, developers may go over the phases if necessary, until the demands are satisfied. When the IT team completes the transition stage, the project is carried out. 

RUP methodology contains six disciplines, such as business modeling, analysis and design, requirements, implementation, testing, and deployments. These processes generally take place during every development phase. Yet the importance of particular disciplines varies depending on the stages. Business modeling, for instance, tends to be conducted during the very first phases – inception and elaboration. 

Rational Unified Process aims at creating reliable web products within certain time limits and a predictable budget. 

It’s time to take a closer look at four effective methodology phases:

1. Inception

The primary task is to analyze if the project is worth implementing. At this stage, all team members should reach an agreement on the scope of the project, including timetables and budget. However, you can increase or reduce the costs or time frames during the development process.

2. Elaboration

The list of actions is quite diverse: you should draw up a development plan, evaluate existing resources and potential risks, and decide on the system architecture. 

3. Construction

Now the team of developers starts up the substantial work regarding system creation and coding. QA and testers, for their part, examine the products’ core competencies. Operational software is a key result of the construction stage. 

4. Transition

Finally, the software is released to end-users. After receiving feedback from the public, the IT team makes a few upgrades and adjustments. Once your app is accepted, the development formally ends.

Why does RUP yield remarkable results?

1. Constant collaboration. RUP developers cooperate with all the stakeholders to achieve excellent results.
2. Leveraging the team efficiency. The IT team can take full advantage of a knowledge base, which helps to share the same language during development phases. Guidelines and mentors’ support are indispensable for overcoming pressing issues.
3. Creating and maintaining models. Forget about a plethora of documents. RUP builds a variety of models that fully represent your system. 
4. Using Unified Modelling Language. UML enables stakeholders to communicate the requirements and responses clearly and interact effectively. 
5. Configurable nature. RUP methodology is suitable for large enterprises as well as fast-growing companies. 

At PNN Soft, we use Rational Unified Process to deal with changing requirements no matter if they are coming from clients or from the project itself. The methodology allows our team to solve complex tasks in a structured way. With the help of RUP, we can also prevent resources from being wasted and cut down on unexpected development costs.
