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 (importance score: 7), run time (length of time until the battery needs recharging, importance score: 10), power (nail penetration, importance score: 10), ease of loading nails (importance score: 7), and ergonomics (size, weight, & balance, importance score: 7).The following text states how a set of important technical requirements (product characteristics) is related to the major customer requirements.-‘Number of nails per second’ has a strongrelationship with Speed-‘Battery life’ has a strongrelationship with Run time-‘Pressure produced’ has a strongrelationship with Powerand a mediumrelationship with Speed-‘Nail loading mechanism’ has a strongrelationship with Ease of loading nails-‘Weight’ has mediumrelationships with Speed, Powerand Ergonomics.Complete the provided matrix and find the importance scores of the technical requirements.
