It's Q4 for most of us, and this is the time of year when revenue operations professionals spend time understanding and redefining sales territories. Sizing territories alone is next to impossible to do by hand, and the tedious process of narrowing down all of the possibilities is expensive, time consuming, and error prone. Even after you've discovered your Total Addressable Market (TAM) in every territory and honed in on select targets, you still have to ensure that your sales and marketing efforts are aligned in pursuit of the targets you've selected. While there are a variety of prospect/customer segmentation tools available to ease the process, there remains a major obstacle in optimizing the right segments and efforts – getting territories right.
