1. What is UX Design?

UX Design is a set of techniques and best practices that make it possible to design products more adapted to the uses of the target users. The idea is to make a break with the design methods used since the 1960s, which put technology at the forefront, to focus more on the possible and probable applications and uses of a technology by given users. This approach, mainly based on cognitive sciences and human factors (interface ergonomics), starts from the observation that a technology without users has no utility and will not generate commitment in the long term.

2. How to set up a UX approach?

There are many tools and references that help in a good conduct of an UX approach:

  • Bastien and Scapin criteria
  • Fitts law
  • Miller’s law
  • Hick’s law
  • Gestalt theory

These repositories all make it possible to better understand the average response of a user when using an interface. However, used separately, even in very large numbers, these tools are not enough because each product is unique and intended for a specific category of users.

Therefore, before using these tools, it is necessary to clarify several points:

  • What is the target of my product?
  • What are the characteristics of this target? (Age group, social level, disabilities, etc.)
  • Does it have any habits to take into account?
  • What are its expectations?

These information are not obvious to collect for a UX Designer alone. They require a lot of prospecting and compilation work. A good solution is to work with the commercial services and base it on market research done or to come. Usually these information are then compiled into Personas, sorts of identity cards of the targeted typical user.

So we understand that we will not design a product in the same way for a young technophile adult or a team of experienced air controllers.

Similarly, the organisation of the company has a strong influence on how the UX approach can and should be implemented. All UX Designer would like to have an infinite time and means but this is almost never the case. Delays are generally short and means limited, as with any service within a company. It is then necessary to choose carefully on which plans our UX approach will focus in order not to disperse the energy of its employees and to have a strong impact on its users.

3. The UX approach at Arone

At Arone, we have chosen to implement a scalable and lightweight UX approach. As the development team operates on an Agile model with one-week development cycles, we preferred to use this model for the UX approach. This makes it possible to do rapid iterations and to have a good margin of manoeuvre in a team on a human scale.

We also use some of the tools mentioned above, including:

  • Bastien and Scapin criteria (General interface ergonomics)
  • Gestalt theory (similarity, continuity of components)
  • The laws of Miller and Hick (information organization)

The objective is, for us, to make the establishment of a clinical study as fast and as simple as possible. Also, we separate each feature as much as possible into coherent and independent sets with the patient form as a pivot. Each new feature that is added is always separated from what has already been implemented.

Another measure that has been put in place to facilitate the clinical approach and integration of customer feedback is the organization of a weekly UX coffee. The goal of this meeting is to bring the team together for a coffee and an UX topic. This could include thinking about implementing a new feature or simply taking stock of the feedback from our customers and prospects regarding the UX of our Arone EDC platform.

This allows us to stay connected to the expectations of our users and ensure that the entire team actively participates in the design choices in the application.

In conclusion, it is important to adapt the UX approach to the capabilities and objectives of the company implementing it. The UX approach is a living entity whose components and monitoring change as the company and its customers evolve. There is no problem using only a small part of the tools and techniques available provided that the expectations of the targeted customers are well targeted.
