The job: turn an outlet list into a repeating weekly route
A beat plan answers one question for a field salesman: which shops do I visit today, and in what order. Behind it sits a harder question for the supervisor — is every outlet being seen as often as its value deserves, and can anyone prove it.
How it is done today
The common version is a route diary. A supervisor who knows the market writes six day-wise lists in a notebook and the reps copy them. It works while one person holds the market in their head.
The next version is a spreadsheet beat sheet emailed to distributors with a tab per salesman. That is a real improvement, because the plan finally exists outside one head. What it still cannot do is confirm the visit happened.
