The ten user centred design methods described here are based on
the principles of ISO
13407, and are recommended when developing software for interactive
systems. Most of the methods are simple to plan and apply, and can
easily be learnt by developers.
Get someone who has used the techniques before to show you how

you could contact one of the European Usability Support Centres.)
Most of the techniques are applied common sense and easy to learn.
