Two books · Seven editable files · 2026 edition
An operating manual for the desk where the hard problems land. A repeatable method for turning raw escalations into framed, evidence-backed recommendations — and the working files to run it on Monday.


ASK Advisor · included
Type the mess as you'd say it out loud. ASK routes it to the right decision path, returns a step-by-step working plan, and cites the exact chapters and templates behind every step — grounded in all 31 chapters, never invented.
Describe a live challenge — one or two sentences is enough.

The premise
“A problem should reach the senior desk with a frame, evidence, options, and a recommendation — not as a symptom looking for an owner.”
Book one
22 chapters, four parts, 130 typeset pages, plus trigger checklists, templates, and worked cases in three appendices.
Book two
9 chapters on market view, competitive power, growth moves, business model, pricing, partnerships, and scaling.
Toolkit
SCQA one-pager, issue tree, process swimlane, ICE backlog, risk register with heatmap, stakeholder RACI with power–interest plot, and a weighted vendor scorecard.
Formats
Typeset PDFs for reading and DOCX / XLSX working files you can edit, rebrand, and hand to the team.
Inside the pages
Every chapter carries a decision card, a worked example from real programs, and the diagrams and tables you can lift straight into a steering deck.


From mess to recommendation, routing the problem, SCQA framing, and MECE structure with evidence.
External change, root cause KPI trees, Pareto focus, pricing the status quo, swimlanes, systems, and the data and control spine.
Option generation, ICE prioritization, reversibility and risk, piloting, vendor lifecycle, and roadmaps that survive change.
AI governance, charters, delivery methods, stakeholder alignment, and the measurement loop that makes a gain persist.
From the practice
“The SCQA one-pager saved a program that was drowning in slide reviews. We now walk into steering with a single page and leave with a decision.”
“The vendor scorecard turned a six-month engine RFP into a defensible three-week decision. The weights force the argument that would have leaked into the room anyway.”
“ASK routes me to the right chapter before I've finished typing the problem. It's the second brain a tax team of one actually needs.”
“The issue tree and the KPI-tree chapter changed how my analysts diagnose e-invoicing rejections. Half the queue disappeared once we stopped treating symptoms.”
“I bought it for the templates and stayed for the framing. The chapter on stakeholder RACI settled a two-year debate about who signs off on ERP change requests.”
“The risk register with the pre-scored heatmap is the first workbook a new hire actually opens on their own. It teaches the method by using it.”
Some reviewers received a complimentary copy in exchange for their honest reference. Quotes are published only with the reviewer's explicit permission.
