The problem begins when marketing and sales measure different things. Marketing measures traffic, leads generated, and cost per click. Sales measures meetings, proposals, and closed deals.
Without a common attribution system, it’s impossible to know which marketing initiatives contribute to revenue and which ones are eating up the budget without having a real impact.
The practical consequence: the budget is allocated based on what seems to be working, not on what the data confirms. When results are disappointing, the debate remains unresolved.
More budget for the same system doesn’t solve the problem. The measurement architecture does.
