(3M) has succeeded
because its business model is based on a culture that is geared to pro-
ducing innovative products. Best known for Post-it Notes, Scotch

transportation, graphies and safety, health cafe, consumer and office,
electronics and communications, and specialty materials.
Because of the company' s unparalleled
success as an innova-

six mandates drive innovation at 3M:
