Almost every company I look at has the same shape of problem, and almost none of them describe it the same way.
The symptom arrives as a sales problem. Not enough pipeline, or pipeline that does not close, or a forecast that misses in a direction nobody predicted. So the response is a sales response: more reps, more activity, a new tool, a harder Monday meeting.
Then you look at the record and the cause is upstream. Nobody decided who this is for, with enough precision that a rep could act on it. Nobody decided which motions the company is running, so it is running five badly instead of two well. Nobody wrote down what a stage means, so the pipeline is a set of opinions with dollar values attached.
The work in this component is deciding those four things on purpose, writing them down, and building the artifacts that make them real in the tools your team already uses.
None of that is a sales problem. All of it lands on the sales team.
