P1 · CHAPTER 03 · 90-DAY EXPERIMENT

90-day experiment for “What Early Looked Like Before

Test “What Early Looked Like Before” through a small, reversible 90-day experiment. The objective is evidence and reusable learning, not proving the book right.

WORKBOOK SEQUENCE

  1. 01

    State the practical hypothesis suggested by: Electricity took forty years to change the factory. The lessons of that lag are written all over the present.

  2. 02

    Choose one observable signal from each theme: The Dynamo Arrives Early; The Factory Before Electricity; Why the Obvious Was Not Obvious; The Productivity Paradox; General-Purpose Technologies Do Not Arrive Alone; Steam, Rail, and the Shape of Rewiring; The Cost of Keeping the Old Layout; AI and the Temptation of the Central Motor; The Thirty-Year Misreading; What the Analogy Predicts; Living in the Lag; The Best Possible News.

  3. 03

    Set a baseline, weekly action, success threshold, cost ceiling and explicit stop condition.

  4. 04

    Review at days 30, 60 and 90; preserve useful examples, distribution or evaluation assets even if the hypothesis fails.

EXPECTED OUTPUT

Leave with a decision artifact.

A 90-day experiment brief with baseline, weekly cadence, thresholds, checkpoints and a final keep/change/stop decision.
