The culture of 3M has become bureaucratic and rigid, with a greater focus on cost reduction. At least this was my experience in the division I worked in. I have heard there are cultural differences across divisions. Micro-management via daily tier board meetings are not conducive to a positive work environment. There are black belts distributed throughout the company serving a 2 year assignment with the expectation of delivering a given cost savings. This generally creates competitive friction across the division.
