3M’s new chief executive says he wants the materials company to improve its innovation process by being more strategic and efficient and accelerating the introduction of new products. “Those are the things I'll be looking at to try to develop more growth coming out of the R&D investment,” said Bill Brown, who took over from Mike Roman in May. His comments came as 3M boosted the floor of its full-year outlook following a quarter in which it beat analysts’ expectations for sales and earnings. 3M shares (MMM) rallied more than 16%.
