3M

The St. Paul, Minnesota materials company that began as a failed corundum mine on Lake Superior's shore in 1902, learned to make sandpaper, then tape, then thousands of products from a shared base of adhesives, abrasives, films and fluorochemistry — and that spent 2018–26 paying for two of them. 3M's manufacturing story turns on invention without liability discipline: a culture that let researchers turn a failed adhesive into the Post-it Note also let the company make PFAS for half a century and sell an acquired earplug design to the US military. In June 2023 3M agreed to pay up to $10.3bn present value over 13 years to US public water systems over PFAS (final approval 29 Mar 2024) and in August 2023 up to $6.0bn, paid 2023–29, to settle the Combat Arms earplug litigation. It committed to exit all PFAS manufacturing by end-2025, spun off its health-care business as Solventum on 1 Apr 2024, and under CEO Bill Brown has been closing plants and rebuilding operating discipline. The lesson for the book: licence to operate is a factor that can go to zero for a product line, and when it does, the rest of the company pays.

8 strategic moves analysed

Each one gets a full strategy file in the companion: context, the decision, the financing, what happened, and the lesson.

1925
Masking Tape and the Culture of Invention
Product launch and production-system culture (a coating platform reused for new products; the 15% rule)
2000
PFOS Phase Out
Environmental case and product exit (voluntary phase-out of perfluorooctanyl chemistry, including PFOS)
2001
McNerney Six Sigma
Production-system change (Six Sigma deployed company-wide, with cost cutting and central sourcing)
2008
Aearo Acquisition and Combat Arms Earplugs
Acquisition, then product-liability case (mass tort, attempted subsidiary bankruptcy, global settlement) — a failure
2022
PFAS Manufacturing Exit
Divestment and footprint closure (end of all PFAS manufacturing, including fluoropolymers, fluids and PFAS-based additives)
2023
Public Water System PFAS Settlement
Environmental liability — class settlement with US public water systems over PFAS in drinking water (failure-driven)
2023
Restructuring and the Brown Operating Reset
Restructuring and footprint consolidation (job cuts, simpler structure, plant and distribution-centre closures, operating-discipline programme)
2024
Solventum Spin Off
Spin-off (health-care business separated as Solventum Corporation)
