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.
