Business Model Canvas

A working Business Model Canvas (BMC) — Alexander Osterwalder's 9-block strategic management template that captures how an organization creates, delivers, and captures value.

When to use this skill

• Designing the business model for a new product or company
• Refreshing the BMC after a strategic pivot
• Stress-testing the assumptions in an existing model
• Aligning leadership on how value flows through the business
• Comparing two or more candidate business models
• Onboarding a new exec / investor to the business

The 9 building blocks

1. Customer Segments — Who do we serve? (mass market, niche, segmented, diversified, multi-sided)
2. Value Propositions — What value do we deliver to each segment?
3. Channels — How do we reach customers? (own, partner; direct, indirect; physical, digital)
4. Customer Relationships — How do we acquire, keep, and grow each segment?
5. Revenue Streams — How does the customer pay? (one-time, subscription, usage, licensing, advertising)
6. Key Resources — What assets are required? (physical, intellectual, human, financial)
7. Key Activities — What do we do to deliver value? (production, problem-solving, platform/network)
8. Key Partnerships — Who helps us? (strategic alliances, JVs, supplier relationships)
9. Cost Structure — Where do costs come from? (cost-driven vs value-driven; fixed vs variable)

Clarify First

Before building the canvas, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Customer segment(s) — who you serve, specifically (drives Value Prop, Channels, Relationships, Revenue — "everyone" collapses the whole canvas)
• Revenue model — how the customer pays: subscription / usage / licensing / advertising (must reconcile against Cost Structure or unit economics break)
• Stage — new model / pivot / mature operating business (determines whether Lean Canvas is the better tool)
• Cost-driven vs value-driven posture — shapes Cost Structure and Key Activities (trying both produces mediocre everything)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Workflow

Step 1 — Draft per block

Start with Customer Segments and Value Propositions (these drive everything else). Then fill: Channels, Customer Relationships, Revenue Streams. Then: Key Resources, Activities, Partnerships. Finish with Cost Structure.

Step 2 — Validate the chain

For each Customer Segment, trace: Segment → Value Prop → Channel → Relationship → Revenue. If you can't connect these, the model has a gap.

Step 3 — Stress-test assumptions

For each block, list the top 2-3 assumptions and rate (high / medium / low) on:

• Evidence (do we know this is true?)
• Riskiness (what breaks if wrong?)
• Testability (can we run a cheap experiment?)

Step 4 — Run canvas_validator.py

Audit the canvas for: empty blocks, ungrounded value-prop / segment matches, revenue / cost imbalance, segment-channel-relationship coherence.

python3 project-management/strategy-frameworks/business-model-canvas/scripts/canvas_validator.py \
  --input canvas.json --format markdown

Step 5 — Iterate

Most first drafts are wrong in interesting ways. Plan to revise 3-5 times.

Decision frameworks

Which type of business model?

Most modern SaaS = multi-sided OR freemium variant.

Cost-driven vs value-driven

Most companies need to pick ONE — trying both produces mediocre everything.

Common BMC anti-patterns

• Generic value proposition. "Better, faster, cheaper" — applies to anything; means nothing.
• One segment listed as "everyone." Forces commodity positioning.
• Revenue streams with no channel. How does money flow?
• Costs that don't sum to revenue model. Unit economics broken.
• Partnerships listed without specific roles. What do they actually do?
• No coherent customer journey across blocks. Segment doesn't connect to channel.

Output expectations

After using this skill, you should have:

1. A populated 9-block canvas with specific (not generic) statements
2. A validation report flagging gaps, ungrounded assumptions, coherence issues
3. 2-3 prioritized experiments to test the riskiest assumptions
4. References to other strategy skills (lean canvas for startup-stage; value-proposition-canvas for the VP block)
