End to End Design

The concept of 'End to End Design' or E2E Design explained. But first this quote.
It is just as inappropriate to have an engineer manage the design process as it is to have a designer who graduated from art college be responsible for the product's engineering details. Business, technical and creative elements must be active throughout all 3 phases of product development. Most importantly they should not be viewed as 3 silos but quite the opposite. This can leave room for an engineering team to offer some suggestions in the earliest stages and the design. The design team who has the prime responsibility of transferring the design to the engineers to insure the desired product design can be built while the engineers have the ultimate responsibility getting it ready for market on time. To go further the teams players should be allowed to play their specialize positions. The designers should not be producing nor should the engineers be art directing the design. Talking and working together? Absolutely.
