Why does our forecast move every month?
Usually not because the market moves but because the stages are not unambiguous: two account managers put the same deal in a different stage, and then the total does not add up. The second cause is hygiene: deals that stay open because nobody closes them. Both can be measured before anything about the process changes.
Can you help if our CRM is not in order?
Yes, and that is usually where it starts. Building a forecast on data that is wrong produces a tidier version of the same problem. We first look at what is in the CRM, what is missing and what contradicts itself, and only then at the reporting.
What if we know something is wrong but not what?
Then the New Data Scan is the cheapest first step: one day on site, fixed price, and you end with a roadmap for 30, 60 and 90 days with an owner for each step. No obligation to continue. That is deliberate: if nothing worthwhile comes out of it, you hear that too.
