Each chapter of The Defensible Decision has a companion page here for material that does not belong in the print book: Power BI Copilot screenshots that age out every six to twelve weeks, vendor-surface inventories, worked-example assets in higher resolution, and the kind of links the book leaves to Appendix D.
Chapter 1 — Why Principles First, AI Later
The thesis chapter. Companion material: the Priya dashboard rendered as a high-resolution comparison, the competence-gap chart, and pointers to Cleveland & McGill (1985) plus the Munzner reference.
Open Chapter 1 →Chapter 2 — Context Before Any Chart
Companion to the BRD discipline chapter. Will host the downloadable BRD template, the executive-vs-operator comparison gallery, and worked-example assets from CloudRevenue.
Chapter 3 — Story: From Data to Argument
Companion to the story discipline chapter. Will host the M365Marketing arc as an interactive walkthrough, the Big Idea template, and the colleague-cold-read protocol script.
Chapters 4 through 14
One page per chapter, added when the book chapter reaches publishable draft. Each page hosts the vendor-surface artifacts the book deliberately keeps out of print.
