Faced with headquarters' desire to add a new product line, Stefan Grenier, manager of Bilti Products' East Division, felt that he had to see the numbers before he made a move. His division's ROl has led the company for three years, and he doesn't want any letdown. Bilti Products is a decentralized wholesaler with four autonomous divisions.
