“Essential” expert evaluation: priority areas for improvement

The “Essential” expert evaluation is an in-depth qualitative analysis designed to diagnose the key areas for improvement in your digital interfaces, whether they are already deployed or in the advanced stages of design.

This process enables the rapid identification of priority areas for usability improvement, with the ultimate goal of ensuring an optimal user experience

Why choose the “Essential” expert assessment?

  • Identification of key priorities: the “Essential” expert assessment allows you to quickly identify priority areas for improvement to optimize your digital interfaces.

  • Transforming challenges into opportunities: thanks to a rigorous and collaborative analysis, this approach converts obstacles into concrete performance levers.

  • Integration and sustainability: user-centric, this method integrates effectively into your processes to guarantee sustainable and measurable results.

A structured and collaborative approach

The process begins with akick-off meetingwith the project team, organized remotely for more flexibility.
This initial session aims to:

  • Clearly define the objectives of the evaluation.
  • Identify specific usability priorities.
  • Select the user journeys to analyze.

This alignment step ensures that the assessment is perfectly targeted to project needs and end-user expectations.

Expert analysis according to best practices

Our usability experts then conduct adetailed analysis of key user journeys, based onrecognized heuristicsand proven evaluation criteria.

Each stage of the journey is studied with rigor, in order to identify potential obstacles to smooth and intuitive navigatione.

Interactive and actionable restitution

The results of the evaluation are shared with the project team during ainteractive remote workshop. This collaborative format promotes:

  • A clear presentation of the problems identified.
  • An in-depth discussion of possible solutions.
  • A direct dialogue between the experts and the project team to better understand the specific constraints and issues.

This interactive session allows us to co-construct a prioritization of the actions to be carried out, in order to ensure effective implementation of improvements.

A clear and operational report

In addition to the workshop, asummary reportis given to the project team.

This document constitutes a practical roadmap, including:

  • A detailed description of the problems identified.
  • Concrete recommendations adapted to the constraints of the project.

This report provides teams with a structured framework for

guide future design and development iterations

A lever for iterative and sustainable improvements

The “Essential” expert assessment fits perfectly into an iterative process, supporting project teams throughout the interface life cycle. It allows you to:

  • Make informed decisions based on objective analyses.
  • Ensure the interface remains aligned with user experience best practices.
  • Lay the foundation for continuous and measurable usability improvement.
  • Adopting the “Essential” expert assessment means investing in a methodical and user-centered approach, for high-performance and engaging digital interfaces.

Usability heuristics

Usability heuristics are fundamental guiding principles which serve as a reference for the evaluation and design of user interfaces.

These principles, popularized by Jakob Nielsen, play a key role in improving the user experience by ensuring that interfaces are intuitive, efficient and pleasant to use. They allow potential usability issues to be detected before users even interact with the product, thus reducing the risk of dissatisfaction or errors.


Based on these heuristics, theDesigners can create interfaces that meet user needs while respecting accessibility and user-friendliness standards.
