4 Project Phases of the Rational Unified Process

There’s nothing worse than putting out a buggy software platform. End users are complaining, people are demanding refunds, and management is not happy. Oh, and you’ve got a lot of extra work to do to fix it.

Just look at the blowback video games like No Man’s Sky and Cyberpunk 2077 have gotten in recent years for releases that critics considered buggy or incomplete. It’s taken years of further development after its initial release for No Man’s Sky to recover some of its reputation — time will tell if Cyberpunk 2077 can do the same. Either way, it’s not a great position to be in.

When developing new software, getting it right the first time is critical. That’s why Rational Software Corp., a division of IBM, developed the Rational Unified Process (RUP) in the early 2000s, which remains popular today. RUP provides a simplified way for software development teams to create new products while reducing risk.

So, what exactly is RUP? This guide will break down how it can help with project execution and how to implement it.


Overview: What is the Rational Unified Process (RUP)?

The Rational Unified Process model is an iterative software development procedure that works by dividing the product development process into four distinct phases:

  • Inception
  • Elaboration
  • Construction
  • Transition

The purpose of breaking it down this way is to help companies better organize development by identifying each phase to increase the efficiency of executing tasks. Other businesses sometimes implement the RUP project management process as a development best practice.


Phases of the Rational Unified Process (RUP)

As noted, there are four project phases of RUP, each identifying a specific step in the development of a product.

Inception

The development process begins with the idea for the project, which is known as the inception. The team determines the cost-benefit of this idea and maps out necessary resources, such as technology, assets, funding, manpower, and more.

The primary purpose of this phase is to make the business case for creating the software. The team will look at financial forecasts, as well as create a basic project plan to map out what it would look like to execute the project and generally what it would take to do so. A risk assessment would also factor into the discussion.

During this phase, the project manager may opt to kill the project if it doesn’t look worth the company’s time before any resources are expended on product development.

What’s happening: The team is creating a justification for the existence of this software project. It’s trying to tell management, “This new software will bring value to the company and the risks appear relatively small in comparison at first glance — as a result, please let us start planning this out in more detail.”

Elaboration

If the software project passes the “smell” test — i.e., the company thinks that on first pass the project benefits appear to outweigh the risks — the elaboration phase is next. In this phase, the team dives deeper into the details of software development and leaves no stone unturned to ensure there are no showstoppers.

The team should map out resources in more detail and create a software development architecture. It considers all potential applications and affiliated costs associated with the project.

What’s happening: During this phase, the project is starting to take shape. The team hasn’t started development yet, but it is laying the final groundwork to get going. The project may still be derailed in this phase, but only if the team uncovers problems not revealed during the inception phase.

Construction

With the project mapped out and resources identified, the team moves on to the construction phase and actually starts building the project. It executes tasks and accomplishes project milestones along the way, reporting back to stakeholders on the project’s process.

Thanks to specific resources and a detailed project architecture built in the previous phase, the team is prepared to execute the software and is better positioned to complete it on time and on budget.

What’s happening: The team is creating a prototype of the software that can be reviewed and tested. This is the first phase that involves actually creating the product instead of just planning it.

Transition

The final phase is transition, which is when the software product is transitioned from development to production. At this point, all kinks are ironed out and the product is now ready for the end user instead of just developers.

This phase involves training end users, beta testing the system, evaluating product performance, and doing anything else required by the company before a software product is released.

During this phase, the management team may compare the end result to the original concept in the inception phase to see if the team met expectations or if the project went off track.

What’s happening: The team is polishing the project and making sure it’s ready for customers to use. Also, the software is now ready for a final evaluation.


4 best practices of the Rational Unified Process (RUP)

RUP is similar to other project planning techniques, like alliance management, logical framework approach, project crashing, and agile unified process (a subset of RUP), but it is unique in how it specifically breaks down a project. Here are a few best practices to ensure your team implements RUP properly.

1. Keep the process iterative

By keeping the RUP method iterative — that is, you break down the project into those four specific and separate chunks — you reduce the risk of creating bad software. You improve testing and cut down on risk by allowing a project manager to have more control over the software development as a whole.

2. Use component architectures

Rather than create one big, complicated architecture for the project, give each component an architecture, which reduces the complexity of the project and leaves you less open to variability. This also gives you more flexibility and control during development.

3. Be vigilant with quality control

Developing software using the RUP process is all about testing, testing, and more testing. RUP allows you to implement quality control at each stage of the project, and you must take advantage of that to ensure development is completed properly. This will help you detect defects, track them in a database, and assure the product works properly in subsequent testing before releasing to the end user.

4. Be flexible

Rigidity doesn’t work with product development, so use RUP’s structure to be flexible. Anticipate challenges and be open to change. Create space within each stage for developers to improvise and make adjustments on the fly. This gives them the opportunity to spot innovative ways of doing things and unleash their creative instincts, which results in a better software product.


Software can help implement RUP in your business

If you’re overwhelmed with planning software development projects, you’re not alone. That’s why project management software is such big business these days. Software can help you implement the RUP process by breaking down your next development project.

Try a few software solutions out with your team and experiment with the RUP process with each of them. See if you can complete an entire project with one software solution and then give another one a try. Once you settle on a solution that fits your team, it will make you much more effective at executing projects.
