Create a memorable experience with the heuristics of Bastien and Scapin

Coming from the human sciences and the ergonomic approach, UX design revolves around tools that are used to judge the usefulness and usability of a computer system. The practice of user experience aims to determine the satisfaction related to the use of functions on the one hand and the way to make them evolve both in substance and in form.
For this, the ergonomists Christian Bastien and Dominique Scapin have created a methodology: heuristic criteria, rules to be respected when designing web interfaces to ensure a better user experience.
Among these tools, there are many standards and recommendations aimed at providing an understanding, a framework for the expertise of ergonomics. This type of tool makes it possible to establish the same strategic bases of ergonomics, in order to potentially avoid all usability defects of an interface.
The analysis defined by Bastien & Scapin is based on 8 criteria:
1) Guidance is one of Bastien & Scapin's most important criteria, it makes it possible to assess all the means implemented to advise, guide and inform the user during his interactions with the digital platform. Four sub-criteria contribute to the Guidance: Incentive, Grouping/Distinction between Items, Immediate Feedback and Readability.
2) The Workload makes it easier and faster for the user to reach their information goals. This allows a more intuitive reading favoring the efficiency of the dialogue. We can cite as an example the Appel site offering us a clear hierarchy of information with a range of minimal actions.
3) Explicit Control: The principle is to demonstrate that each action of the system corresponds to an explicit request from the user. Their actions must be anticipated and controlled so that each option is appropriate to each case requested by the user.
4) Adaptability: Is the capacity of the system to react according to the context, and according to the needs and preferences of the user. For this it is important that the system be flexible allowing a personalized adaptation of the interface in order to provide the user with a strategy, a habit of use.
5) Another important point, Error management: since it is in the nature of human beings to make mistakes, we must foresee that the user will make errors, we must therefore design means to avoid or reduce errors to overcome this problem. For this, the interface must protect the user against possible errors, he must be warned when there is a problem and help or anticipate errors in order to help the user.
6) Homogeneity and consistency of the interface is also one of the primary criteria. The interface design choices (graphic codes, denominations, procedures, etc.) must be retained throughout your site to immerse the user in identical contexts that promote overall understanding.
