<b>Definition drift: how shifting lead stages silently rewrite partner economics</b>

A quiet but consequential problem in partner programs: the definitions of MQL, SQL, and sales-accepted lead drift over time, and when payout triggers on these stages, the drift redistributes money without anyone deciding to.

<b>The mechanism.</b> Lead-stage definitions are maintained by marketing and sales ops, who tune them for forecasting accuracy — tightening MQL criteria to reduce sales complaints, for instance. If partner payouts trigger on MQL, tightening the definition cuts partner pay as a side effect no one intended or communicated.

<b>Why it's invisible.</b> The payout rule ('we pay on SQL') stays constant in the contract, so it looks stable. The underlying definition of SQL moves underneath it. Partners see falling conversion rates and blame their own performance, when the goalposts moved.

<b>Benchmark relevance.</b> Cross-program lead-quality benchmarks are nearly meaningless without definition control, because one vendor's MQL is another's raw lead. Per marketing-ops commentary, stage-definition inconsistency is the single largest source of non-comparability in funnel benchmarks.

<b>The governance trade-off.</b> Freezing definitions to protect partners harms forecasting accuracy; letting them float for accuracy destabilizes partner economics. You can optimize the funnel for measurement or for contractual stability, not effortlessly for both.

<b>Implications:</b> if your program pays on a funnel stage, version-control the stage definition and notify partners on change, the way you'd treat a price change. An uncommunicated definition tweak is a pay cut administered by spreadsheet.
