Work the Policy Not the Exception

3 min readStatus:Seedling

Core Idea

When an exception request seems reasonable, that is evidence the policy needs updating — not that this person deserves special treatment. Default to working the policy, not granting the exception.

Work the policy, not the exception is Will Larson’s principle that engineering managers should respond to exception requests by improving the underlying policy rather than granting individual workarounds.

Why Exceptions Are Harmful

  • Precedent and scaling: Every exception is an implicit commitment to grant it to anyone in similar circumstances. With 100 engineers, informal negotiation collapses.
  • Manager-as-bottleneck: Exception-granting concentrates decision power in the manager; people learn to advocate with the manager rather than follow the system.
  • Systematic unfairness: Only those who ask — or ask well — receive exceptions. Quieter team members and newer joiners systematically receive less.
  • Exception debt: Accumulated exceptions form an invisible parallel policy — inconsistent, informal, and resentment-generating. See Exception-Debt.
  • Cognitive load: Each exception requires re-litigating context and tracking precedent — costs that compound with team size.

When Exceptions Are Appropriate

  • Genuine emergencies that no policy could anticipate — unique, one-time circumstances
  • Discovery mechanism: grant the exception AND immediately update the policy
  • Explicit one-time events — name them as non-repeating when granting, and track them

Four-Step Response Framework

  1. Ask: Is this request exposing a gap in the policy?
  2. If yes: Fix the policy first, then apply the updated policy to this person
  3. If no: Grant explicitly as a named, one-time exception
  4. Track: If you grant the same exception twice, that’s a policy gap — update the policy

Procedural Justice Angle

Research on procedural justice (Thibaut & Walker, 1975; Tyler, 1990) shows that consistent rule application is perceived as fair — even when the outcome is unfavorable — because the process signals respect and impartiality. Policy consistency is not just operationally efficient — it is perceived as more just.

Connection to Systems Thinking

The principle applies Deming’s distinction between common cause variation (systemic issues requiring policy change) and special cause variation (unique circumstances justifying individual response). See Systems-Thinking-Stocks-Flows-Feedback.
