Every chemistry roadmap was credible and none of them agreed
A corporate venture capital arm inside an industrial group had to commit to a battery chemistry, the mix of materials a cell is built from, for a programme it was backing. The commitment sets what the programme can buy and who it can buy from for years, and it is expensive to reverse once volumes are being built.
The choice is rarely settled on how the cell performs. It turns on how deep the supply chain for those materials runs, on what the companies that assemble cells into packs can actually build around, and on which suppliers will still exist when the programme reaches volume. Those considerations sit in different heads. A briefing document collects them without ever making them argue.
We worked the decision rather than collecting a briefing
We ran a workshop with former cell engineers, who have taken a chemistry to a production line, pack integrators, who build the finished battery around the cells, and procurement leads, who have had to buy the materials. Between them they held the views a document would have listed side by side without resolving.
The session was scoped backwards from the commitment the team had to make rather than around the topic, which is the difference between a working session and an interesting one. It was chaired so the trade offs were argued out in front of the team rather than listed, with the people holding the competing views in the same room and the decision itself on the table. Everyone cleared our compliance checks first.
A commitment the team could defend inside the group
The session produced a chosen direction, with the trade offs written down and the conditions for revisiting it named in advance. That mattered as much as the choice. Venture decisions inside a large group get challenged internally, and a decision with its reasoning visible survives that in a way a conclusion does not.
The group became a standing reference for the programme. Chemistry questions keep coming back as a roadmap moves, and the same practitioners were called back each time rather than replaced with a fresh search.
