Pascal Raabe (#jazzpazz), a graphic designer and student based in Bristol, has released a really nice poster explaining user centred design.
You can download it for free in PDF of JPG format, and you can order a high quality, A1 sized printed copy in return for a donation towards Pascal’s studies.
Delve below the surface of a good design to find out how it was developed and why it works. Test and iterate as you go along.
The diagram neatly brings together various threads of though about UX and user centred design, from the “planes” of Jesse James Garret’s elements of user experience, through to Leisa Reichelt’s clever ideas about the design and development process (agile vs waterfall).
