The Iterative Design Process: A Full Guide for UX Designers

Additionally, customers are more happy with the iterative process because they can get improvements earlier. This method helps you to have clear communication with customers and encourage them to provide feedback. The iterative process is a feedback loop based on re-analyzing and improving the product according to new data or customer feedback. Iterative design allows more teams to work on different things at the same time. For example, one designer could work on the UX while another one is in charge of adjusting page elements that developers had issues with.
Measuring the Success of Iterative Design Projects
You can think of the iterative design process as a continuous cycle of prototyping, testing, and making adjustments and refinements. It’s because it is almost always cheaper and easier to create a prototype to test than it is to develop a system or product and then amend that based on user feedback. There are a huge number of tools on the market that allow you to create interactive prototypes for web and software applications and most of these are low cost to adopt. If you have perfectionist tendencies, it’s scarier to show the client something less than perfect. However, if you tell them the project’s in the early stages and you just want feedback, they’ll likely be more understanding.

You will learn about the key principles of agile, examples of teams that perform all the agile “rituals” but aren’t actually agile, and examples of teams that skip the rituals but actually embody the spirit. Instead of aiming for some nebulous version of a perfect design, aim for getting things good enough to learn from and iterate. By approaching your website or app as a living and evolving project rather than something static, you can consistently improve upon it. One part of a digital experience is designed, created, and tested, and is built upon in future designs. It’s a powerful – and increasingly common – method for developing websites and apps, and it’s at the core of current ideas about effective digital marketing. Typically, if you’ve only had one iteration so far, the chances are that you’ll need to iterate at least once more.
Differences between Design Thinking and Agile
This approach ultimately leads to a more user-centered and effective design. Bring together a team with diverse expertise, including engineers, designers, and product managers, to collaborate on the project and ensure a holistic approach. Conducting one-on-one interviews or group discussions with users can help project managers gather in-depth information about their experiences and opinions. This paper was written while the author was a member of the Applied Research Division of Bell Communications Research (Bellcore).

In addition, the approach allows customers to be involved during the development process, leaving no place for retroactive changes to be made after deliverables are released. Iterative design can also foster innovation and creativity within engineering teams. By encouraging collaboration, experimentation, and feedback, iterative design can help project managers push the boundaries of what is possible and explore new ideas. This approach can lead to breakthrough solutions that may not have been possible with a more traditional design approach. To effectively measure KPIs, engineering project managers must gather both numerical data and subjective insights from users.

As a result, without a clearly defined timeline and milestones, product design might be stuck in an infinite iteration loop and run out of time while iterating the design to make it perfect. The iterative model significantly slashes the budget allocated for rework, making it a fiscally prudent choice. With its data-backed iterations, this approach promises not just cost savings but also robust returns on investment. Once you have the green light on your design, the team can create a physical or digital prototype for user testing and validation in a real-world or testing environment.
For example, I recently performed a usability evaluation of a telephone company application. Improvements in the user interface based on this study were estimated to result in a reduction in training time of half a day per user and a speedup in expert user performance of 10%. Given the number of users and their loaded salaries, these numbers translate to savings of $40,000 from reduced training costs and about $500,000 from increased expert user performance in the first year alone. In this example, the overall value of the usability improvements is obviously dominated by expert user performance -- especially since the system will probably be used for more than one year.
Why Use an Iterative Process?
With your problem and solution defined, you can move on to create a project plan and gather requirements. These are things that have to happen for your project to succeed, so you’re not just iterating endlessly without hitting your goals. Research might involve user surveys, gathering data on user behavior, and having ongoing conversations with clients and stakeholders.
Don Norman describes the evolution of user-centered design and why he believes user-centered design (and its newer avatars) can help address global issues. The course "Design for a Better World with Don Norman" provides an in-depth understanding of these principles and how they can be applied to create designs that positively impact humanity. This detailed description helps seed the imagination of designers and enables them to ask critical questions like "Would Betty understand this feature?" or "How would Betty feel about using this aspect of the system?".
Two ways of obtaining expert users without having to train them are to involve expert users of any prior release of the product and to use the developers themselves as test users. Of course, one should keep in mind that a developer has a much more extensive understanding of the system than a user would have, so one should always test with some real users also. User-centered design (UCD) is an iterative design process in which designers focus on the users and their needs in each phase of the design process. In UCD, design teams involve users throughout the design process via a variety of research and design techniques, to create highly usable and accessible products for them.
She encourages designers to get comfortable with the idea of a design not being perfect. Notice the many parallels between Laura’s advice for designers on agile teams and the mindsets of design thinking. In the “Inspire” phase, the team focuses on understanding users’ needs, behaviors, and motivations.
