Define both good-enough criteria and over-investment thresholds for each output type — cap effort to prevent perfectionism on low-stakes work

Why This Is a Rule

Most quality management defines the floor — the minimum standard below which output is unacceptable. But perfectionism isn't a floor problem; it's a ceiling problem. You keep improving past the point where additional effort produces meaningful quality improvement. The 80th percentile of quality takes 20% of the effort; the 95th percentile takes 80%. For most output types, the value difference between 80th and 95th percentile is negligible to the audience while the effort difference is 4x.

The dual-threshold approach addresses both boundaries. The good-enough criteria define the floor: "Does this meet the minimum standard for its purpose?" The over-investment threshold defines the ceiling: "Am I spending more effort than this output type warrants?" The floor prevents under-delivery; the ceiling prevents perfectionism. Together, they create a quality band: below it needs more work, above it needs less.

The over-investment threshold is the innovation: it gives you permission to stop. "This email has been drafted, spell-checked, and says what it needs to say — stop revising the second paragraph for the fourth time." Without an explicit ceiling, the internal quality critic has no stopping rule and will always find something to improve. The threshold provides the external stopping rule that the internal critic lacks.

When This Fires

• When creating quality standards for your common output types (Annotate each output type with its half-life (hours/weeks/months/years) — calibrate investment in durability and polish to actual lifespan)
• When you notice spending 3x longer than needed on low-stakes outputs
• When high-stakes outputs are delayed because effort was consumed by low-stakes perfectionism
• Complements Annotate each output type with its half-life (hours/weeks/months/years) — calibrate investment in durability and polish to actual lifespan (half-life annotation) with the specific quality boundaries for each lifespan category

Common Failure Mode

Floor-only standards: "Everything I produce should be high quality." Without a ceiling, "high quality" means "as good as I can possibly make it," which for a perfectionist means infinite effort on every output. The email takes 30 minutes instead of 5, the meeting notes take 45 minutes instead of 10, and the important report gets pushed to tomorrow because today's hours were consumed by over-polished ephemeral work.

The Protocol

(1) For each output type in your taxonomy (Annotate each output type with its half-life (hours/weeks/months/years) — calibrate investment in durability and polish to actual lifespan), define two thresholds: Good enough (the minimum standard — what must be true for this output to be acceptable), and Over-investment (the maximum effort/time — the point beyond which additional polish produces no meaningful value improvement). (2) Good-enough criteria should be binary and checkable (Define completion as binary observables (draft exists) not subjective evaluations (draft is good) — clear termination prevents perfectionism spirals): "Spell-checked, key points present, action items clear." Not "well-written." (3) Over-investment thresholds should be time-based: "Slack message: 2 minutes max. Email: 5 minutes max. Weekly report: 30 minutes max." (4) When you hit the over-investment threshold, stop. Ship it. The output is good enough, and the effort belongs elsewhere. (5) If you consistently exceed the over-investment threshold for a specific output type, either the threshold is too tight (adjust upward) or you're perfectionism-spiraling on that type (practice stopping).
