Key to the results of this project was interpretation of the results gathered through user testing. Numerical evaluation using test rigs provided precise quantitative results, but conversational interviews provided equally important qualitative information on consumer attitude and preference. Observation of users performing tasks was also important. Many problems were to do with users performing secondary tasks such as battery changing or accessing the carrying case for the tools - aspects people generally left out of their formal reports.

The study showed that correctly incorporating user need and feedback into the design process can create a better product. And when those users have special needs such as reduced dexterity or arthritis, addressing their needs in a mainstream product design brief can provide innovative triggers as well. A power tool that is designed to be easier to hold, will be easier to hold for everyone who uses it - not just retired people.

Can listening to users help designers and manufacturers approach newly created markets in a fresh, rather than conventional manner? B&Q thinks so. It subsequently developed two of the concepts - the cordless screwdriver and palm-sized sander - into full production models for launch onto the market in autumn 2002.
