Companies and organizations have less and less time to launch and complete their projects. The pressure of competition is one of the causes. This lack of time, and this need for speed in reaching objectives, impacts all aspects of a project. We have therefore seen the emergence of new so-called ” Agile ” methods , which provide more Japan Phone Number List and flexibility , at all stages of a project. This is particularly the case during the development phase. To be in phase during the UX design, a method respecting the same “Agile” principles is particularly suitable. Here is what the Lean UX method consists of , and some explanations on how it works.


Evolve within an “Agile” context lean-ux Lean UX is a useful technique when working on projects where an agile development method is used. Traditional UX techniques may not be suitable when development is done in rapid iterations : there isn’t enough time to keep UX up to speed . The hallmark of Agile development is to operate in rapid and iterative cycles . Lean UX aligns with these cycles to ensure that the data generated can be used with each iteration. To achieve this speed, this saving of time, the Lean UX method notably uses hypotheses or assumptions : what would the user do , how would he behave, what would be his use of the product?

Lean UX finds its source in ” lean manufacturing “, a method itself derived from the Toyota Production System (TPS) method. Because of this “manufacturing” origin, Lean UX is based on a set of principles that aim to maximize value and minimize losses in design . In traditional UX, the project is based on the collection of needs and the deliverable product. The aim is that the deliverables are as detailed as possible and adequately meet the requirements defined at the start of the project. Lean UX is slightly different. We do not focus on the detail of the deliverable .

We are making changes that improve the product here and now . The concept of MVP To achieve these objectives in a short time, the Lean UX method also adopts the concept of MVP : Minimum Viable Product. What you could translate to: The smallest answer you can craft that delivers customer value . The idea is to build the most basic version of the product, test it, and abandon it if there is not enough results. MVPs that look promising can be incorporated into new phases of design and development. This method makes it possible to maximize the use of resources , and to obtain immediately usable products , even if they are imperfect.

The Lean Ux Method

Untitled-Project A good illustration of this idea, given by Henrik Kniberg, is to imagine that your customer wants to obtain an autonomous means of transport, safe and sheltered from the rain. A traditional method would be to start from the idea of a wheel, then going through multiple stages and a lot of research, to design a car that we can, only at this stage, test. The intermediate stages have no customer value: a wheel or a chassis is not usable in itself. The Lean UX method based on MVPs would rather offer a skateboard, which would be very quickly usable. Then, after testing, would add a handlebar to obtain a scooter, itself usable.

Then, would see with the user that a saddle would be welcome, and would produce a bicycle. We would add an engine for less effort, so we would offer a motorcycle. Finally, to be truly sheltered and safe, we would obtain a car with the addition of a bodywork and doubling the wheels. We would therefore have a deliverable that can be used and assessed at all stages of the project , improved with the designer team and the client by iteration at each stage of the project. What you must remember Lean UX is particularly suited to the digital environment and the speed of design that it implies. It responds to new needs for change and adaptation. This is why this method is used more and more, and therefore better and better documented .
