Nobody has written the plan down, and sales is already pitching
There is a product, a price and a rough idea of who it is for, but the positioning, the personas and the channel split were never decided in one place. Get back positioning, personas, a channel plan and a messaging grid, researched against the product, the market and the competitors, as the plan itself rather than the assets.
The first real customer result is still in a thread
A deal closed, the numbers are good, and the write-up that would win the next three has not been made because it is a day of writing nobody has. Get it back as a structured document, in editable Word with a matching PDF, every figure traced to the source you pointed it at.
The same proposal, retyped for every new kind of buyer
One proposal works, and then the next segment needs its own version, and the next after that. Multiply the finished piece along the axes your workspace already has set up, up to 12 combinations, each queued as its own variant from the same source.
