What makes a good sales territory design?

Balance across territories on both potential and workload, coherent grouping so coverage is efficient, and explicit accounting for the cost of disrupting the existing alignment. All four appear in the formal alignment literature.

How does territory design affect performance measurement?

Directly. If territories differ materially in potential, attainment differs for reasons preceding any selling behaviour, so ranking sellers on attainment partly ranks the map.

How often should territories be redrawn?

Often enough that drift does not accumulate, rarely enough that disruption cost does not dominate. Incremental rebalancing at the margin generally beats periodic wholesale redraws, because disruption is a real cost in the alignment models rather than an afterthought.

Should territories be geographic or by segment?

Whatever makes coverage efficient and potential balanced. Geography matters where travel is required; where selling is remote, segment or industry grouping usually produces better coherence.

Territory Design

Dividing accounts among sellers so each has a patch with enough potential to support a quota, and so coverage is neither duplicated nor absent.

Four criteria

What a good alignment satisfies

Criterion	Requirement	Consequence when ignored
Balance on potential	Comparable opportunity per territory	Attainment differences measure the map
Balance on workload	Comparable coverage effort	Some territories unservable at any skill level
Coherence	Accounts grouped so coverage is efficient	Travel and context-switching consume selling time
Disruption cost	Change from current alignment is costly	Redraws destroy relationship capital already paid for

Disruption is a cost, not a consideration

In the formal models, change from the existing alignment carries an explicit cost. An alignment that is optimal on potential but reassigns most accounts can be worse than a suboptimal one left alone — which is the case against the annual wholesale redraw.

The measurement consequence

Where territories differ in potential, attainment differs before anyone sells anything. A common response to underperformance — reassigning accounts away from the underperformer — increases imbalance and makes the next ranking worse. The loop is self-confirming and invisible unless potential dispersion is measured.

Diagnostic

Compute a potential figure per territory using a consistent proxy, before looking at attainment. Report the ratio of highest to lowest.
Compare potential dispersion to attainment dispersion. If potential varies threefold and attainment twofold, most of the performance difference is the design.
Count accounts requiring coverage per seller. High potential with unmanageable account count is not a good territory.
Plot potential against attainment, one point per seller. Points below the trend are coaching candidates; the spread on the potential axis is a fact about the map.

Where it is harder than it looks

Potential is estimated, and a poor proxy produces a confidently balanced map that is not balanced.
Existing relationships have value that account-level potential does not capture, which is part of why disruption is costly.
Optimising potential alone produces territories that fail on workload, and vice versa — both criteria have to bind.

The rules assigning each inbound lead to a specific owner — by territory, segment, product, account ownership or round-robin.

Segmentation

Dividing the market into groups that warrant different treatment — different motion, pricing, coverage or support model.

Capacity Planning

Quota

The revenue target assigned to an individual rep for a period. The most consequential number in a seller's working life, and the mechanism translating a company target into individual accountability.
