Most of the time the honest answer is not yet. Not because the number is small. Because I have not read anything yet.
I once watched a sales director answer that question in under ten seconds. He may well have been in the right order of magnitude. He also had no way to defend it when his finance director asked how he got there, and the conversation closed, the way those conversations usually close.
Here is the part the total hides. The number is not the finding. The finding is the condition that produces it, and memory is the last source for that, not the first.
What would settle it is dull work. Four weeks of calendars for the eight people who rebuild the thing, and the edit history on the stage that carries two meanings. Then each of the eight asked separately, in their own words, what their Monday actually looks like, before anyone is shown the records.
Even done properly, that establishes what those four weeks cost that team in that quarter. It is not a law about pipeline stages, and it is not your number.
So if you want the figure this week, write down first where you would go to get it. If the answer is that you would ask around, you already have your first finding.
