Proposal and scoping

Week 1 at Northbridge. The proposal is the deliverable clients judge before they trust you with deliverables - and AI now drafts one in minutes. Every minute saved moves the weight onto the two parts AI cannot do: the scoping judgment that decides what you will NOT do, and the promise you sign. This session drafts the Cadence proposal, builds the first hypothesis tree, and frontier-maps the week-1 task list so you know exactly which parts to delegate.

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.

★ What you walk out with today A one-page Cadence proposal with the question in ONE sentence, three written scope exclusions, a three-branch hypothesis tree with a counter-hypothesis per branch, and every number in the draft marked sourced or flagged.
Part 1 · covers the proposal craft

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.

1 · Context: why Cadence, why now 2 · The question, in one sentence 3 · Approach: workstreams, week by week 4 · Team and governance 5 · Fees 6 · Terms: the promise you sign AI drafts this well - minutes, not hours; you review for invented specifics yours alone: choosing the ONE question is the scoping decision itself AI structures the weeks; the EXCLUSIONS (what you will NOT do) are pure judgment the fee prices your judgment and your accountability, not drafting speed the promise carries a human signature - that is Rail 2 from session 1 AI drafts the first pass human owns Written scope exclusions in week 1 prevent scope fights in week 4 - the cheapest insurance in consulting.

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.

Real worldThe 758-consultant BCG field experiment found AI-assisted work converged on similar ideas even as quality rose - a floor-raiser that homogenizes. In proposal terms: the AI-draftable sections are now table stakes nobody wins on. Firms still win engagements on the sections this diagram paints dark blue - the question, the fee, the promise - which is why this session spends its twenty working minutes there.
Part 2 · covers the method

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.

HYPOTHESIS · STATED WEEK 1, TESTED FOR SIX Cadence should launch an enterprise tier IF demand exists 62% of trial teams hit the seat cap; 210 in procurement IF the economics favor it retention 94% vs 71%; ARPU lift 2.1x at $30/seat IF the window is open rivals price $38-45/seat; room to enter at $30 Workstream 1 · weeks 2-3 validate demand: usage data, the procurement pipeline Workstream 2 · weeks 2-4 model the economics: ARPU, retention, pricing scenarios Workstream 3 · weeks 2-3 scan the window: rival pricing, moves, positioning AI's best prompt on this tree: "what would make this false?" - counter-hypotheses, never the tree itself.
🔍 Click to zoom - the Cadence tree: each IF-branch becomes a workstream in the plan
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.

Part 3 · covers the delegation call

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.

ZoneWeek-1 tasksThe rule
INSIDEdraft the context section, restructure boilerplate, generate counter-hypotheses for the treedelegate freely, review for invented specifics
EDGEmarket sizing claims - AI will happily invent one that reads perfectlyevery number needs a source before it enters the proposal (b3 builds the full discipline)
OUTSIDEscope exclusions, the fee, the promise in the termsnever delegated - these carry your signature
Real worldThe classic week-1 self-own: a proposal shipped with an AI-invented market-size stat in the context section. It reads exactly like a real one - session 1's study showed outside-frontier output arrives just as confident and polished as inside-frontier output, which is what made AI users 19 percentage points less likely to be right there. In a proposal, the client's first fact-check is your last impression. Mark every number sourced or flagged before the document leaves your desk - the fifty-minute discipline that b3 turns into a source log.
The one-line test before anything enters the proposal "If the client asks where this came from in the kickoff meeting, do I have an answer that is not the name of a model?" If no: source it or cut it.

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.

✦ If you finish early Ask AI to draft the same proposal cold, with no case facts supplied. Compare it to yours. The difference - their numbers, their seat cap, their procurement pipeline - is what client-anchored writing means, and it is exactly what the session-5 scorer measures.

Homework 📝 ◐ 20 minutes

Check yourself

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.
