Map Value Chain + Profit Pools

For a defined industry, decompose the value chain (Porter) and overlay absolute economic profit (Bain / Gadiesh-Gilbert) by stage. Output: value-chain-profit-pools.md with stage-by-stage profit map and identification of where structural profit concentration sits.

The discipline: profit and revenue are frequently inverted along the value chain. Mapping revenue without economic profit produces a misleading picture. Use EBIT or economic profit (not gross margin, not revenue share).

Iron rules:

• Profit measured as absolute EBIT or economic profit per stage, not revenue margin or revenue share.
• Normalised over 3-year trailing average margin (5-year for cyclical industries).
• Ranges, not point estimates — every stage EBIT carries a low–base–high range.
• Horizontal-bar visualisation required (markdown table with bar-width proxy).
• Structural protection statement required: name a Helmer 7 Power for the highest-EBIT stage. If none identifiable, state "not structurally protected — expect arbitrage" explicitly.
• Cross-references to working/five-forces.md if present (the governing force should correctly predict the profit-pool location).
• When stage capital intensity varies >2×, escalate metric from EBIT to economic profit (EP) — see `references/economic-profit.md`. This is a hard rule, not a recommendation: validator fails if capital-intensity data is disclosed with >2× max/min ratio and only EBIT is used.
• Append a structured next_skills: YAML block at end of file for orchestrator hand-off.

Process

1. Intake

Confirm: industry slug, geographic scope, value-chain definition (which stages — use a sector-appropriate template from references/value-chain-templates.md, including the vertical-integration and platform Z-shape notes). Read references/profit-pool-methodology.md.

2. Decompose the value chain

List 5-9 stages from raw inputs to end customer. For each: brief description, 2-3 representative players, estimated revenue contribution to total industry revenue as a range (low–base–high), V/C/A/I-tagged.

3. Estimate absolute economic profit per stage

For each stage, estimate EBIT in absolute dollars, normalised over 3-5 years, expressed as a range. If stage capital intensity is disclosed and max/min ratio >2×, you MUST use economic profit (EP / NOPAT minus capital charge) — not EBIT — see `references/economic-profit.md`. If capital intensity is not disclosed, EBIT is acceptable but the validator will warn you to disclose it. Method: listed-comparable triangulation — see references/listed-comparable-triangulation.md for the 5-step protocol (pure-play ≥70% revenue concentration; GAAP EBIT including SBC; 3-year average; median across n≥3 comparables; disclose dispersion). Document method + comparables per stage.

4. Generate profit-pool visualisation

Use the template in assets/profit-pool-template.md. Produces a horizontal-bar markdown table where bar width is proportional to absolute EBIT (base case). Optional executive river-chart variant for orchestrator hand-off.

5. Identify structural profit concentration

Name the stage with highest absolute profit concentration. Then answer: why does profit concentrate here? The answer must name a Helmer 7 Power — scale economies / network economies / counter-positioning / switching costs / branding / cornered resource (incl. regulatory) / process power. Apply the per-power diagnostic questions in references/structural-protections.md — do not just assert the label. If no structural reason is identifiable, state: "not structurally protected — expect arbitrage by [named entrant] within [horizon]."

6. Cross-reference Five Forces

If working/five-forces.md exists, reconcile: does the named governing force correctly predict the profit-pool location? E.g., "buyer power high" should NOT coexist with "the customer-facing stage captures the most profit." If contradictory, flag for orchestrator Gate 2 reconciliation.

7. Validate + write output

Run python scripts/validate_profit_pools.py --output-path <path> — checks: EBIT or EP used, absolute $ figures, bar visualisation, named Helmer power (or explicit unstable-finding), V/C/A/I tag coverage ≥5, anti-pattern protections rejected ("adds value", "critical", "differentiation", etc.), capital-intensity >2× requires EP, structured next_skills: YAML block present. Soft warnings on missing normalisation disclosure, false precision, flat pools, and missing capital-intensity disclosure. Write to working/value-chain-profit-pools.md (orchestrator) or standalone/map-value-chain-profit-pools-YYYY-MM-DD.md (standalone).

HTML on request (standalone only): markdown is the default and the only format the validator and the orchestrator consume. If the user explicitly asks for an HTML version of a standalone run, then after validation passes, also render the output via the html-output skill and review it per ../_shared/output-conventions.md § "HTML deliverables and quality review". Never produce HTML automatically.

8. Append next_skills YAML block

At the very end of the output file, append a fenced YAML frontmatter block declaring next recommended skills for orchestrator Phase 2 automation. Minimum one entry. Example:

---
next_skills:
  - assess-moat-sources    # to assess durability of the structural protection identified
  - map-five-forces        # if Five Forces not yet present, for cross-reference reconciliation
---

Gotchas

• Symptom: profit pool shown as revenue margin % per stage instead of absolute EBIT $. Cause: drafter confused gross margin with economic profit. Fix: validator rejects any output where the profit metric is a percentage. Absolute $ is required because two stages with identical margins can have very different profit concentration when revenue scales differ.
• Symptom: structural protection statement reads "the manufacturing stage captures most profit because it adds the most value." Cause: circular / non-structural reasoning. Fix: the protection must be a Helmer power. Validator rejects "adds value", "is critical", "differentiated", "first-mover" (alone), "expertise" (alone), "relationships" (alone), "quality", "complexity" (alone). See references/structural-protections.md for the full anti-pattern list and per-power diagnostics.
• Symptom: profit pool location contradicts Five Forces governing force without flagging. Cause: sub-skills run independently without cross-reference. Fix: step 6 requires reconciliation; orchestrator's Gate 2 surfaces the contradiction.
• Symptom: every stage shows similar EBIT (flat profit pool). Cause: likely an estimation error or comparable-set contamination. Fix: validator warns on flat pools. Justify explicitly (e.g., "late-commoditisation phase — see evidence") OR re-estimate with tighter pure-play comparables.
• Symptom: stage EBIT quoted as "$1.94B" with no range. Cause: false precision — triangulated estimates carry ±20-30% irreducible uncertainty. Fix: validator warns; express as low–base–high ranges.
• Symptom: EBIT compared across stages with materially different capital intensity (e.g., fabless vs. foundry). Cause: EBIT understates profitability of capital-light stages relative to capital-heavy. Fix: upgrade to economic profit per references/economic-profit.md when capital intensity varies >2×.
• Symptom: single-year margin print used. Cause: noisy in cyclical industries. Fix: normalise over 3-year trailing average (5-year for cyclicals).

Rules

• Never use revenue margin or revenue share where absolute EBIT/economic profit is required.
• Never declare a profit-pool location without naming the Helmer power that sustains it (or declaring it unstable).
• Never quote stage EBIT without a range.
• Never use a single-year margin without normalisation justification.
• Never skip the Five Forces cross-reference when both files exist.
• Every numeric claim carries a V/C/A/I tag.
• All file reads use encoding='utf-8'.

Old patterns

v1.2 (2026-05-18) added hard rule: capital-intensity >2× forces EP (not just EBIT); validator parses capital-employed columns and inline numbers. Added structured next_skills: YAML block for orchestrator Phase 2 hand-off. v1.1 hardened Helmer-power vocabulary, added economic-profit + listed-comparable + structural-protections references, strengthened validator with anti-pattern rejection and quality warnings.
