Must the EHR operating instructions be so complicated? http://www.ehrwatch.com/blog/must-operating-instructions-be-so-complicated
Segmenting and dissecting implementation and product operating instructions in isolation is not appropriate. It all starts with product design, which you alluded to in the beginning. The easier and simpler the product, the more difficult it is to design and build on the backend. Ask any engineer and software designer. Ask Apple. But, once you design a truly simple product, simplicity in operating instruction and therefore implementation is an extension of that philosophy.
