What usually happens: Most territory design is states dragged into buckets in a spreadsheet, balanced by headcount rather than by opportunity. Nobody can say whether the books are actually even, so every rep believes theirs is the bad one.
What we build instead: Territories built as a geospatial and optimization problem, which is what they are. Accounts scored on real firmographics and intent, balanced on potential rather than count, and written into the CRM as owner assignment rules that hold.
