p5 ping pong model

The best way to illustrate the possibilities of human-centred design is with what we call the P5 Ping-Pong model; it illustrates when (phases) and how (which methods and communication)research could support  the product development process.

Each of these phases has its own specific methods, mostly qualitative. Because people’s judgements often rely as much on perceptions as on facts, qualitative research intended to identify existing perceptions has great value. Face to face interviews, focus groups, ethnographic research, usability tests in a lab or on site and in-home tests as well belong to the possibilities.

Design teams’ timescales are often pressured.  Organizing, researching, analysing and reporting the results have to be carried out in only a few weeks time.

If research is not presented in an usable format, it will be discarded or ignored. That is why we put so much effort in the communication with the client. We prefer to have a workshop to present and discuss all research findings before delivering the final report. As a tool for communication and implementation of the research findings we developed the P5 script approach.
