Business Model Canvas

Framework

IRON LAW: All Nine Blocks Must Be Completed and Consistent

The BMC is a SYSTEM — each block depends on others. A value proposition
without a matching customer segment is an invention, not a business.
Revenue streams without cost structure analysis is wishful thinking.
Fill ALL nine blocks and check that they tell a coherent story.

The Nine Building Blocks

#	Block	Question	Right Side (Value) / Left Side (Efficiency)
1	Customer Segments	Who are we creating value for?	Right
2	Value Propositions	What value do we deliver?	Center
3	Channels	How do we reach customers?	Right
4	Customer Relationships	How do we interact with customers?	Right
5	Revenue Streams	How do we make money?	Right
6	Key Resources	What do we need to deliver value?	Left
7	Key Activities	What must we do well?	Left
8	Key Partnerships	Who helps us?	Left
9	Cost Structure	What are the major costs?	Left

Block-by-Block Guide

Customer Segments: List distinct groups with different needs. Mass market? Niche? Multi-sided platform?

Value Propositions: For EACH segment, what problem do you solve or need do you fill? Be specific — "quality" is not a value prop. "Same-day delivery of organic groceries" is.

Channels: How do customers discover, evaluate, purchase, receive, and get support? Map the full journey.

Customer Relationships: Self-service? Personal assistance? Community? Automated? Co-creation?

Revenue Streams: For each segment: what do they pay? How? (subscription, transaction, licensing, advertising, freemium)

Key Resources: Physical, intellectual (IP, data), human, financial — what's essential?

Key Activities: Production? Platform management? Problem solving? Sales?

Key Partnerships: Suppliers, strategic alliances, joint ventures. WHY partner? (optimization, risk reduction, resource acquisition)

Cost Structure: Fixed vs variable. What are the biggest cost drivers? Cost-driven or value-driven model?

Analysis Steps

1. Fill all 9 blocks with sticky-note level detail (short phrases)
2. Check CONSISTENCY: Does the value prop match the segment? Do channels reach the segment? Do revenue streams justify the cost structure?
3. Identify RISKS: Which blocks have the most uncertainty? These are your riskiest assumptions.
4. COMPARE: Map current model and proposed new model side by side

# Business Model Canvas: {Business}

## Canvas

| Block | Description |
|-------|-----------|
| **Customer Segments** | {who} |
| **Value Propositions** | {what value, for which segment} |
| **Channels** | {how you reach and serve} |
| **Customer Relationships** | {type of relationship} |
| **Revenue Streams** | {how you make money} |
| **Key Resources** | {essential assets} |
| **Key Activities** | {critical operations} |
| **Key Partnerships** | {key partners and why} |
| **Cost Structure** | {major cost categories} |

## Consistency Check
| Connection | Consistent? | Notes |
|-----------|------------|-------|
| Value Prop ↔ Segments | ✓/✗ | {match?} |
| Channels ↔ Segments | ✓/✗ | {reachable?} |
| Revenue ↔ Cost | ✓/✗ | {profitable?} |

## Riskiest Assumptions

Gotchas

• BMC is a starting point, not an answer: It structures thinking but doesn't validate assumptions. Each risky block needs Lean Startup-style testing.
• Revenue model is the hardest block: "Users will pay" is an assumption. How much? How often? Willing to pay based on what evidence?
• Multi-sided platforms need separate segments: Uber has drivers AND riders. Each segment has its own value prop, channels, and revenue model. Map both sides.
• Don't confuse activities with resources: "Software development" is an activity. "Engineering team" is a resource. "Source code" is a resource. Separate them.
• BMC should be a living document: Review and update quarterly. Business models evolve — the canvas should reflect current reality, not the original plan.
