Controlled test design

  • Hypothesis: Test a limited spend increase on confirmed combinations with a protected control.
  • Comparison: Incremental spend group versus stable-budget control and portfolio totals
  • Specify assignment, group overlap, exposure and contamination checks.
  • Choose a primary metric, detectable effect and completed outcome window before calculating sample size.
  • Set risk budget, guardrails, checkpoint and stop or restore conditions.

Acceptance checks

  • Failed tests and failed promotions remain in search cost.
  • Cost of finding a winner is separate from post-promotion production spend and quality.
  • Decision owner, risk budget, guardrails, checkpoint and restore condition are specified.
  • Assignment, detectable effect and outcome horizon are specified before the test starts.

Deliverables

  • A pilot design with success and stop criteria
  • Agreed scope, source requirements, responsibilities and acceptance checks.
  • A working brief for a readiness and delivery conversation, not a completed investigation.
