I agree with Jonathan’s comment that involving both operations and finance is crucial. The best outcomes will result from having diverse perspectives, which will come from early and regular collaboration across teams. Working in a silo has too many pitfalls, since no one person or team knows how every other functional area operates, what works well, what is difficult, etc. I’m not suggesting decisions by committee, but keeping a small group informed and talking to one another will likely lead to better outcomes and more trust.
