# BMC Antipattern and Misunderstanding Correction

## Purpose

Quickly recognizes when BMC work is going wrong — either in how the work
is being done (antipatterns), or in what the client/team assumes the BMC
will do for them (misunderstandings) — and offers the expert's own, direct
corrective moves for each. This is a diagnostic and corrective skill: use
it mid-session, when something feels stuck.

## Anchored in

- The owner's April 2026 expert interview,
  two `status: accepted` / `confidence: high` files in the owner's
  research notes:
  - `30_domain_packs/bmc/antipatterns/bmc_antipatterns_expert.md` — five
    of the expert's own antipatterns.
  - `30_domain_packs/bmc/facilitation/bmc_client_misunderstandings.md` —
    four of the most common client misunderstandings about the BMC's role.

## Method

### A. Five antipatterns — recognize them in how the work is done

1. **Too much content per block.** Sign: several revenue streams,
   segments, or channels "active" at the same time. Consequence: clarity
   is lost, no coherent path emerges (focus segment → focus channel →
   focus value proposition → focus revenue streams). **Fix:** force
   choices. One segment, one channel, clear revenue streams. Extra
   options → a new variant, not an addition to the same canvas.
2. **Too deep too early.** Sign: the team invests heavily in polishing
   one canvas before producing variants. Consequence: no variants get
   produced, the canvas stays "multi-option" instead of sharpening.
   **Fix:** enforce a sprint structure, a time limit per phase — see
   `../bmc-canvas-clarity-and-iteration/SKILL.md`.
3. **Canvas as a strategy document.** Sign: the team treats the canvas
   as a final strategy or planning document, not an iteration tool.
   Consequence: over-polishing individual word choices instead of
   searching for the unique combination. **Fix:** remind them of the
   role — the BMC is a thinking and innovation tool, not a plan.
4. **Starting from the left side.** Sign: the session starts from key
   activities / key resources / key partners. Consequence: the canvas
   builds up around production logic rather than customer logic; the
   value proposition ends up disconnected. **Fix:** always start on the
   right: customer → problem → solution → value proposition → revenue
   streams → left side.
5. **One canvas is enough.** Sign: the team produces one canvas and
   considers the work done. Consequence: no basis for comparison,
   innovation patterns can't be identified from a single canvas.
   **Fix:** at least 2-3 variants before the analysis and synthesis
   phase — see `../bmc-canvas-clarity-and-iteration/SKILL.md`.

### B. Four client misunderstandings — recognize them in what's said

1. **"This could define everything at once."** The client is thinking:
   the BMC is the key to everything — filling it in once produces a
   finished business plan. Reality: the BMC is primarily a thinking tool.
   It doesn't replace more precise planning tools. **Response:** walk
   through the BMC's role as a thinking and innovation tool — not a
   planning deliverable.
2. **Too deep too early (the client's version).** The client tries to
   produce a perfect canvas on the first attempt. Consequences: no time
   for variants, clarity is lost, no focus anywhere. **Response:** the
   work needs to be iterative and fast. Light first, vary, then go deeper.
3. **Canvas = a complete business planning tool.** The client expects the
   BMC to be enough for all their planning. Reality: once the business
   model has been innovated, more precise product specifications,
   profitability and growth-margin scenarios, and other more precise
   tools follow the BMC. The BMC is no longer the optimal tool once the
   innovation decision has been made. **Response:** see
   `../bmc-tool-switching-decisions/SKILL.md` for what comes next.
4. **One canvas is enough (the client's version).** Reality: value comes
   from variants and comparing them, not from a single canvas. One
   canvas → one business model. Value emerges once there are 2-3
   variants → they can be analyzed, scenario-tested, synthesized.

## Gotchas

- Antipatterns 2 and 5 (too deep too early, one canvas is enough) are named
  here but actually fixed by `../bmc-canvas-clarity-and-iteration/SKILL.md`'s
  variation mechanics — diagnosing the antipattern without switching to that
  skill's sprint structure and 2-3 variant minimum just re-describes the
  problem instead of solving it.
- Antipattern 3 ("canvas as a strategy document") and misunderstanding 1
  ("this could define everything at once") sound almost identical but target
  different audiences — the working team's behavior vs. the client's belief
  about what the BMC delivers. Misreading which one you're facing means
  offering a facilitation nudge when a role explanation was needed, or vice
  versa.
- Misunderstanding 3 (canvas = complete planning tool) points the fix to
  `../bmc-tool-switching-decisions/SKILL.md`, but this skill doesn't itself
  say WHEN that handoff should happen — naming the misunderstanding without
  pairing it with the actual switching criteria leaves the client's real
  question ("what do I do next?") unanswered.
- This is explicitly a 5+4 list from the expert's own practice, not an
  exhaustive taxonomy — a session that's stuck for a reason that doesn't
  match any of these nine patterns needs a different diagnosis, not a forced
  fit into the nearest-sounding antipattern.

## What this skill does NOT do

- Doesn't replace the actual variation process — see
  `../bmc-canvas-clarity-and-iteration/SKILL.md` for the concrete
  iteration mechanics. This skill is a detection-and-correction toolkit,
  not a process guide.
- Doesn't cover a canvas's internal diagnostics (Hook Rule, evidence
  grade, etc.) — see `../bmc-canvas-diagnostic-reading/SKILL.md`. The
  antipatterns in this skill concern WORKING METHOD and CLIENT
  EXPECTATIONS, not the content quality of a finished canvas.
- Isn't an exhaustive list of every possible mistake — these 5+4 are the
  most common ones that have come up in the expert's own practice, not a
  comprehensive taxonomy.

## Continue from here

- Related skill in the same pack:
  `../bmc-canvas-clarity-and-iteration/SKILL.md` — antipatterns 2 and 5
  are corrected directly by this skill's variation logic.
- Related skill in the same pack:
  `../bmc-canvas-diagnostic-reading/SKILL.md` — once the canvas is
  finished, a more precise reading of internal consistency.
- Related skill in the same pack:
  `../bmc-tool-switching-decisions/SKILL.md` — the fix for
  misunderstanding 3, when the BMC is no longer the right tool.
