The goal of this book is to teach you how to apply the principles of lean to design.
Lean UX is not an individualistic working technique but rather it’s a technique that connects designers with their fellow team members to bring about a greater collaborative process. It is a mix of design thinking, agile software development and lean startup. The first step of Lean UX is design thinking where every aspect of the business is approached with design in mind. The second is agile software development where every team member is involved in the product development process from the start and throughout the whole duration of the project. The third is the lean startup method which is a strategy that thrives on fast-paced experimentation and validation.
In order to put Lean UX into practice, you need to create assumptions which are essentially business ideas. Using these three aspects: outcomes, personas and features you can turn your assumptions into a testable hypothesis statement.
Rather than implementing a traditional approach where the designer works separately from the product team until the last few stages, design studio brings the designer and the other team members together from the start to develop design solutions to the problems the company may face. Through this approach, a diverse number of outlooks and expertise are put into play thus ending in a smoother process. Now, it’s time to test your hypothesis.
The best way to test your hypothesis statement is to use the Minimum Viable Product (MVP). To design and present a prototype, there are two approaches: paper prototyping or medium/high fidelity. Paper prototyping is an approach of sketching or writing different pieces of information on a page but fails to produce a simulation that adequately resembles the experience of the final product. While medium/high fidelity produces a stronger simulation of the quality of a product, it can be very time consuming. When you are delivering software, it is best to deliver an MVP to test your hypothesis. This could be a simple website that frames the business, but requires significant manual processing in the background. Typically, you should test your MVP once a week to gain continuous feedback.
Lean UX is not simply a process but needs to be looked at as a mindset. Having a more engaged working environment which fosters collaboration will bring Lean UX into play.
