Principle
A compensation plan does not drive behaviour. A rep's understanding of the compensation plan drives behaviour, and in most commercial organisations these two things have drifted meaningfully apart. The plan on paper may be beautifully designed. What reps believe it says is what actually determines where they spend their week.
Behaviour
Compensation plans in growth-stage companies are frequently revised, often annually and sometimes more, and each revision adds a clause, a modifier, or a special case designed to correct some behaviour observed in the prior period. Over a few cycles, the document becomes long, technical, and full of interlocking conditions that require genuine effort to model against a specific individual's expected book of business.
Reps do not do that modelling. They read the plan once, form a simplified mental heuristic about what pays, and then operate off that heuristic for the rest of the year. The heuristic is usually approximately right about the largest component and frequently wrong about everything else. A carefully designed multi-year contract bonus that pays out generously goes unclaimed because the reps believe, incorrectly, that it only applies to new logos. A modest kicker on gross margin goes unnoticed entirely. The plan's intended behavioural signal is transmitted at a fraction of its designed strength.
A plan that would produce ideal behaviour in a rep who fully understood it is not a good plan if no rep fully understands it.
Evidence
Ask five reps individually, without warning and without allowing them to consult the document, to explain how they get paid. Specifically, ask them to rank the components of their plan by how much each is worth to them and to describe any bonus, kicker, or accelerator they are eligible for.
Compare their answers to the actual plan document. In most organisations the divergence is immediate and substantial: components are missed entirely, thresholds are misremembered, and the ranking of what pays most is frequently wrong. Where reps give materially different answers to each other about the same plan, the plan is not functioning as a communication instrument at all.
A useful confirming test is to compare where reps say they spend their time against where the plan would rationally direct them to spend it. Systematic divergence, particularly in areas the plan supposedly incentivises heavily, indicates the incentive is not reaching the behaviour it was designed to shape.
Psychology
Reps are not being careless. Modelling a complex compensation plan against a specific pipeline is genuinely difficult analytical work, it is not what reps were hired to do, and the payoff for doing it correctly is uncertain and deferred while the cost is immediate. Building a rough heuristic and getting on with selling is, for most reps most of the time, entirely rational time allocation.
Compensation designers, for their part, tend to evaluate a plan by whether its incentive structure is theoretically sound rather than by whether it is comprehensible to the person it is meant to motivate. A plan that would produce ideal behaviour in a rep who fully understood it is not a good plan if no rep fully understands it, and complexity is added far more readily than it is ever removed.
Commercial Risk
An investor examining a portfolio company's compensation plan is examining the plan as designed, not the plan as understood, and it is only the latter that produces revenue behaviour. A plan that appears to align reps with margin, multi-year contracts, and strategic account penetration may in practice be driving nothing but new logo volume, because that is the only component the reps have internalised.
This has direct consequences for any post-acquisition thesis that relies on redirecting commercial behaviour through compensation redesign. Redesigning a plan that reps did not understand in the first place will not produce the intended behavioural change unless the communication problem is solved alongside the design problem, and most remediation plans address only the latter.
There is a second-order cost as well. Where reps have misunderstood a plan for several periods, the organisation has been paying for behaviours it never received while receiving behaviours it never intended to pay for. The plan's total cost has been incurred in full. Its intended effect has been realised only partially, and nobody has ever measured the gap because the gap has never been visible in any report anyone runs.
