The deliverable before the deliverables
No client has ever read your analysis before reading your proposal. It is the one document where the firm's judgment is on display with no data to hide behind: what you think the question is, what you will and will not do, what it costs, and what you promise. AI drafts most of it well - context, boilerplate, structure, a credible first-pass approach - which is exactly why the parts it cannot draft now carry all the weight. Today you write the Northbridge proposal for the Cadence engagement, and you learn to tell the two kinds of parts apart on sight.
The plan: the anatomy of an engagement proposal and the AI-vs-human split (Part 1), the hypothesis tree that turns a question into a workplan (Part 2), and a frontier map of the week-1 task list using session 1's lens (Part 3). Then twenty minutes of drafting for real.
Anatomy of the engagement proposal 7 min live
Six sections, in the order the client reads them: context, the question, the approach by week, the team, the fees, and the terms. For Cadence, the question is already fixed by the brief: should Cadence launch an enterprise tier, and how? Everything else in the document exists to make that question look inevitable and the plan look safe.
LiveWhat AI drafts well, and the three things it cannot4 min▶
Hand AI the Cadence brief and it will produce a competent context section, clean boilerplate, a sensible document structure, and a first-pass approach - the parts that used to eat an analyst's evening. Take those gains; session 1 called refusing them malpractice. But three parts of the proposal sit outside the frontier, and they happen to be the three parts the client actually judges:
What to EXCLUDE from scope. AI expands scope by default - ask it for an approach and it will cheerfully include everything adjacent. Deciding that this engagement answers enterprise-tier-or-not and does NOT redesign the product and does NOT renegotiate infrastructure costs is a judgment about what six weeks can honestly deliver. The fee. A number that prices your accountability and the client relationship - no model has that context. The promise. The terms section is what the firm signs; session 1's liability rail says every commitment reaching a client has a human owner. That is nowhere more literal than on the signature page.
The exclusions deserve one more beat, because they are the real craft. An unwritten exclusion is an argument waiting for week 4, when the client "assumed pricing redesign was included." A written one costs two sentences in week 1 and settles the argument before it exists. Your drafting exercise today requires three of them, in writing.
Self-studyWhy AI-drafted proposals all sound the same2 min▶
Session 1's study had a second-order finding worth re-reading in a proposal context: AI-assisted output homogenized - answers converged on similar ideas. A proposal is a competitive document; if three firms pitch the same client with AI-drafted approaches, the context sections will be interchangeable. What cannot converge is the part drawn from judgment: the one question you chose, the exclusions you dared to write, the specific fact from THEIR business (62% of trial teams hitting a seat cap says more about Cadence than any market overview). Differentiation lives exactly where delegation stops.
The hypothesis tree, first cut 7 min live
Consulting does not gather facts and hope an answer emerges - it works hypothesis-first. State the likely answer on day one, structure what must be true for it to hold, and plan the work against each branch. The proposal's approach section is really a hypothesis tree wearing a calendar.
LiveBuilding the tree, and what AI is actually for here4 min▶
The tree reads top-down: "Cadence should launch an enterprise tier" holds IF demand exists, AND the economics favor it, AND the market window is open. Each branch is checkable against evidence you can name today - the seat-cap number and the 210 procurement accounts for demand, the 94-vs-71 retention split and the ARPU math for economics, rival pricing at $38-45 for the window. And each branch spawns a workstream, which is how the tree becomes the approach section: the plan is not "research the market," it is "test branch two by week 4."
AI's role on the tree is precise and valuable: it generates counter-hypotheses and missing branches. "What would make this false?" is a superb prompt - it will suggest that the 210 accounts entered procurement to satisfy security teams rather than to buy, or that individual-plan churn is driving the retention gap rather than enterprise stickiness. Some suggestions will be noise; the two that sting are worth the whole exchange. What AI never does is decide the tree - stating the likely answer is the engagement's central act of judgment, and it belongs to whoever signs the proposal.
Self-studyHypothesis-first is not answer-first-and-forever2 min▶
The discipline is stating the likely answer so the work can attack it, not defending the answer against the work. Each branch carries an implicit kill condition: if the procurement pipeline turns out to be security theater, branch one falls, and the recommendation moves. The tree you draft today gets rebuilt with real findings in b4, becomes the storyline's skeleton in b5, and gets scored in the readout. Write it in pencil; test it in ink.
Frontier-mapping week 1 5 min live
Session 1 gave you the map - INSIDE, EDGE, OUTSIDE the frontier. Now apply it to the actual week-1 task list, because the proposal is where the first invented statistic tries to enter the engagement.
| Zone | Week-1 tasks | The rule |
|---|---|---|
| INSIDE | draft the context section, restructure boilerplate, generate counter-hypotheses for the tree | delegate freely, review for invented specifics |
| EDGE | market sizing claims - AI will happily invent one that reads perfectly | every number needs a source before it enters the proposal (b3 builds the full discipline) |
| OUTSIDE | scope exclusions, the fee, the promise in the terms | never delegated - these carry your signature |
Draft the Northbridge proposal 📝 ★ 20 min · everyone works
No lab widget yet - the scorer debuts in session 5, and today's drafts are what it will eventually eat. One page, real sentences, using only the case facts from session 1.
Draft the one-page proposal. Context, question, approach, team, fees, terms - use AI for the first pass or write it by hand, but use only the case facts: 62% seat-cap, 210 accounts, 94% vs 71%, rivals at $38-45, entry at $30, ARPU 2.1x.
Write the question as ONE sentence. Not two, not a paragraph. If your sentence needs an "and also," you have two engagements and one budget.
Write THREE scope exclusions. In full sentences a client could read. Start from the two the session named - no product redesign, no infrastructure-cost renegotiation - then find a third the Cadence brief tempts you toward.
Build the hypothesis tree. The three branches - demand, economics, window - plus ONE counter-hypothesis per branch. Ask AI "what would make this false?" and keep the two suggestions that sting.
Mark every number. Go through your draft: each number is either sourced (a case fact) or flagged for verification. If AI added a number you cannot trace, you just caught your first invented statistic - cut it and remember the feeling.
Trade drafts and attack the scope. Swap with a neighbor and ask the week-4 question: "what will the client assume is included that you did not write down?" Every assumption they find is an exclusion you owe the document.
Homework 📝 ◐ 20 minutes
- Scope something real. Take one live project or engagement of your own and write its question in one sentence plus three exclusions. Notice which exclusion you hesitated to write down - that is the week-4 fight you just prevented.
- Run the counter-hypothesis prompt on your own work. State your current project's likely answer, ask AI "what would make this false?", and keep the two answers that sting. Bring them to b3 - they become research questions.
- Audit one AI draft for unsourced numbers. Any recent AI-drafted document: highlight every figure and trace it. Count how many you cannot. b3 opens with that count.
Three questions before you go 🎯 ◐ 90 seconds
1 · AI drafts the context, boilerplate, and first-pass approach of a proposal well. The three parts it cannot do are...
Exclusions are a judgment about what six weeks can honestly deliver, the fee prices your accountability, and the terms carry a human signature - Rail 2. AI expands scope by default; consultants earn their fee by shrinking it in writing.
2 · Working hypothesis-first means...
The tree is written in pencil: each IF-branch carries a kill condition, and the work attacks the hypothesis rather than defending it. AI contributes counter-hypotheses ("what would make this false?"), never the tree itself.
3 · The classic week-1 trap this session warned about is...
Invented statistics read exactly as confident and polished as real ones - that is what made outside-frontier AI users 19 percentage points less likely to be right. Every number in the draft gets marked sourced or flagged; b3 turns that habit into a source log.
