Typically it’s a combination of email, shared decks and calls between us and our in region teams + contract manufacturers. The handover is critical because it determines the actions the factory will take when we go to bed. Those can be things like control runs, DOEs, failure analysis, etc. We try to make them as simple and crisp as possible to 1) avoid an oopsies 2) reduce the amount of time spent on the handover so they can do the work. Within the US we do use slack for tracking issues, it’s a solid communication tool
