Product-development processes traditionally used by manufactur-

ers start with market researchers who study customers in their tar-

get markets to learn about unsatisfied needs. Next, the need infor-

mation they uncover is transferred to in-house product developers

who are charged with developing a responsive product. In other

words, the approach is to find a user need and to fill it by means of

major customers and from customer panels, and information from

lab personnel. Non-LU teams collected market information from

target markets users but not from lead users.

Findings

515

Our research compared all funded product concepts generated by

516

LU and non-LU methods from February 1999 to May 2000 in each

of the five 3M divisions that had funded one or more lead-user-

developed product concepts. During that time, five ideas gen-

erated by lead user projects were being funded, along with 42

ideas generated by non-LU idea-generation methods. The results

of these comparisons can be seen in table 10.1. Product con-

cepts generated by seeking out and learning from lead users were

found to be significantly more novel than those generated by non-

LU methods. They were also found to address more original or

newer customer needs, to have significantly higher market share,

to have greater potential to develop into an entire product line,

and to be more strategically important. The lead-user-developed

product concepts also had projected annual sales in year 5 that

were greater than those of ideas generated by non-LU methods

by a factor of 8---an average of $146 million versus an average

of $18 million in forecast annual sales. Thus, at 3M, lead user

idea-generation projects clearly did generate new product concepts

with much greater commercial potential than did traditional, non-LU

methods (p < 0.005).
