I think a finance function earns its place by helping the business decide faster, not by closing the books faster.
As CFO of an engineering firm with 900 people, I replaced the annual budget with a quarterly forecast that project leads own. Spending approvals that needed three weeks are now settled in four days.
Before that I spent eight years in audit, which is where I learned what a slow decision costs.
I write now and then about finance that supports the business rather than policing it, and I am always glad to compare notes with other finance leaders.
