TETRA approach : developer, designer, ergonomist and orchestrator

The adoption of rich client is not only a craze for a new fashion concept, it’s a response to a request from users thinking that computing should be simple and intuitive. Technologies and tools are being put in place, but we need to think how to design applications involving more user in the visual interface. Rich client now allows us to realize all that users can imagine and it’s this ability that makes this concept innovative. The problem is that the user does not always able to imagine what would be the best UI for him, we must involve people who know the business, mastering ergonomics conceptss, have knowledge of design and how it can cost in terms of development. It’s this set of skills that we must coordinate to answer to the expression of user needs. We can sum up this approach in the form of a tetrahedron:


Orchestrator have the particular role of reconciling the technical and the visual with the trade. The difficulty lies in finding the person who is familiar with the three above concepts and is able to understand the subtleties of different trades. In my opinion, the success of a rich client project go through this approach.
