In the mid-2000s, DeWalt, a Black and Decker brand, saw the need of carpenters and do-it-yourselfers for a cordless battery-operated nailer. At that time, the only automatic nailers in the market were pneumatic ones that were cumbersome because of the need for a compressor and a hose. DeWalt consulted and observed carpenters at work and determined the following customer requirements: speed, run time (length of time until the battery needs recharging), power (nail penetration), ease of loading nails, ergonomics (size, weight, and balance), being able to see the nail going in, and being able to work in tight spots. The following matrix shows the major customer requirements, their importance score (in brackets) and a set of technical requirements, "Number of nails per second has a strong relationship with Speed 'Battery life has a strong relationship with Runtime "Pressure produced' has a strong relationship with Power and a medium relationship with Speed "Nail loading mechanism has a strong relationship with Ease of loading nails 'Weight' has medium relationships with Speed, Power and Ergonomics.
