You are the one who has to answer for the spend
You are not short of dashboards. You are short of a number you would be willing to defend in front of someone who wanted to argue with it. Especially if you answer to an owner, a board or an investor who is going to ask what the money bought.
This is you if
- You spend meaningfully on marketing and cannot say what it produced
- Your reports look good and you cannot tell whether they should
- You know who you lose deals to but not why
- Somebody is going to ask you for marketing ROI this quarter
