The easiest way to "sell" some ideas/solutions to get other people to come up with the ideas.
If you've read The Bottleneck Detective you'll see that it's all about making small, focused tweaks.
- Focus
- Tweak
- Repeat
The secret is figuring out where to focus (the detective's work)
The tweaks are usually just common sense (and they come from the whole team).
Common sense sells itself.
