What T-Mobile US's office footprint means for territory planning
Use Bellevue, WA for executive and corporate account mapping, then map field and functional hubs to the actual buying problem. Territory planning should account for time zones, operating divisions, store or network footprints, distribution centers, studios, venues, and technology hubs.
For ABM and field events, prioritize the cities where budget owners and implementation teams actually sit. A headquarters-only plan will miss many practical buyers in operations, IT, supply chain, media, retail, and regional leadership.
