The Decision-to-Outcome System
This google ads case is presented through the same five stages: diagnose the constraint, validate the evidence, decide the move, execute it, and prove the change.
Find the commercial constraint before choosing a channel task.
Input: Website, account, tracking, feed, margins, demand, or buyer prompts.Check the data, economics, demand, and implementation reality behind it.
Output: Trusted baseline, attribution, margins, lead quality, stock, and access limits.Choose the highest-leverage move and make the trade-offs explicit.
Output: One priority, target metric, assumptions, exclusions, and decision date.Ship the smallest coherent intervention that can change the outcome.
Output: Owner, sequence, dependencies, approvals, and validation method.Read the result against revenue, margin, pipeline, or qualified demand.
Output: Metric movement, confidence, exclusions, unintended effects, and next decision.Repeat: evidence from Prove becomes the next Diagnose input.
