What is the Business Model Canvas? (Short answer)
Business Model Canvas — BMC is a strategic tool comprising 9 blocks that helps you describe the entire way a business creates, delivers and captures value, all on a single page. Instead of writing a business plan dozens of pages long, BMC lets you see the big picture, identify gaps and adjust your idea much faster.
This tool was introduced by Alexander Osterwalder and Yves Pigneur in the book Business Model Generation and is now widely used in entrepreneurship programs, business schools and incubators worldwide. BMC's strength is its visual nature: you can put it on a wall, use sticky notes and update it continuously without rewriting it from scratch.
Why Should New Entrepreneurs Use the BMC Before Doing Anything Else?
Many young people start businesses on instinct: they see an appealing idea and immediately rent premises and order stock. Only once operating do they discover that they do not know their target customers, have not considered how to collect revenue or lack clear distribution channels.
BMC helps you avoid exactly those traps. When you have to fill in all 9 blocks—from customers and the value you offer to your cost structure—you immediately see which parts remain unclear or unworkable. This is the cheapest and fastest way to screen an idea before committing real capital.
Practical Principle: A business idea with all 9 BMC blocks not yet completed is an untested idea. Do not invest money before completing the canvas.
A Detailed Explanation of the 9 Business Model Canvas Blocks
Below are the individual boxes in a logical order—from “who you serve” to “how you earn and spend money.”
Block 1 — Customer Segments (Customer segments)
This is the fundamental question: Whom are you creating value for? Do not write a vague ‘everyone’—be specific about their age, occupation, behavior, pain points and desires.
Block 2 — Value Propositions (Value propositions)
What problem do you solve for customers? What makes your product or service worth paying for? This is the heart of the entire model. A strong value proposition must answer: ‘Why do customers choose me instead of a competitor?’
Block 3 — Channels (Access channels)
How do you deliver your product or service to customers? This includes both marketing channels (so customers discover you) and distribution channels (so they can buy). Examples include social media, physical stores, delivery apps, and websites…
Block 4 — Customer Relationships (Customer relationships)
What kind of relationship do you want to build with customers? Self-service, personal assistance, community, or automation? This block directly affects operating costs and customer loyalty.
Block 5 — Revenue Streams (Revenue streams)
Where does your revenue come from? Direct sales, subscription fees, commissions, advertising, or data sales? A business can have several revenue streams—list them all and identify the main one.
Block 6 — Key Resources (Core resources)
What resources do you need to operate your business model? There are four main types: physical assets (premises, machinery), intellectual assets (brand, formulas, copyrights), human resources, and finance.
Block 7 — Key Activities (Core activities)
What must your company do every day to create and deliver value? These are essential activities: if they stop, the business is immediately affected.
Block 8 — Key Partnerships (Core partners)
Who do you need to complement what you lack or do not want to do yourself? Partners may include raw material suppliers, transport providers, technology partners, or strategic investors.
Block 9 — Cost Structure (Cost structure)
What are the biggest costs of operating this model? Distinguish fixed costs, such as rent and salaries, from variable costs, such as ingredients and sales commissions. This block connects directly to Revenue Streams so you can calculate profit margins.
Example of Completing a BMC for a Café
Suppose you want to open a small café focused on specialty coffee, serving office workers and freelancers in the city center. Here is what a basic BMC might look like:
- Customer segments: Office workers aged 22–35, freelancers and final-year students seeking a quiet workspace, and people who value coffee quality over low prices.
- Value proposition: Specialty coffee prepared by certified baristas; a quiet space with power outlets and reliable Wi-Fi; a menu clearly stating the regional origins of the coffee beans.
- Outreach channel: Instagram and TikTok to build awareness; Google Maps to help customers find you; ordering apps (Grab Food, ShopeeFood) for takeaway orders.
- Customer relationships: Baristas provide advice directly at the counter; loyalty cards earn points; Zalo/Facebook groups let regular customers receive special offers.
- Revenue streams: Selling drinks for on-site consumption (main activity); selling takeaway drinks through apps; selling packs of roasted ground coffee; organizing brewing workshops (secondary activity).
- Core Resources: A 40–60m² space, a professional espresso machine, 1–2 skilled baristas, a café brand, and proprietary drink recipes.
- Core activities: Prepare and serve drinks; control ingredient quality; create social media content; look after regular customers.
- Key partners: A specialty coffee roaster supplying consistent beans; a premises landlord; suppliers of milk and other ingredients; delivery platforms.
- Cost structure: Rent (fixed and the largest expense); barista salaries; ingredients (varying with revenue); marketing costs; equipment depreciation.
When you look at all 9 boxes together, you can immediately ask these checking questions: “Does my value proposition really match the chosen customer segment? Does the revenue stream cover the cost of renting premises?” — This is the core value of this tool.
Common Mistakes When Completing a BMC for the First Time
- Writing Too Vaguely: Statements such as “Our customers are everyone” or “Our value is good quality” offer no analytical value.
- Skipping the Costs and Revenue blocks: Many People Focus Only on the Product Idea and Forget Financial Feasibility.
- Fill it in once and stop: BMC is not a static document. It needs updating whenever you learn something new from the market.
- Not validating with real customers: Completing the BMC is only the first step. You need to go out and test each assumption with real users.
- Confusing ‘Activities’ with ‘Resources’: Resources are what you have (machinery, people, money). Activities are what you do (production, marketing, service).
Take action now: Complete your BMC in 60 minutes
Here is a suggested process for completing your first canvas today:
- ✅ Step 1 (10 minutes): Print or hand-draw the 9-box BMC framework on A3 paper, or use a free online tool (Canvanizer, Miro, Strategyzer).
- ✅ Step 2 (5 minutes): Write Your Idea or Product’s Name at the Top of the Page. Keep It Unchanged—Do Not Edit It While Filling In the Rest.
- ✅ Step 3 (10 minutes): Fill in the block Customer segments first. Describe at least 1–2 specific customer groups with clear characteristics.
- ✅ Step 4 (10 minutes): Fill in the block Value proposition. For each segment, what problem do you solve or benefit do you create?
- ✅ Step 5 (20 minutes): Fill in the remaining 7 boxes in turn—use sticky notes if you want to make changes easily later.
- ✅ Step 6 (5 minutes): Read through everything again and mark the boxes you uncertain in red ink. That is the list of assumptions to test next.
- ✅ Step 7 (ongoing): Share the canvas with at least 3 people: an industry insider, a potential customer, and someone who knows nothing about your idea. Listen to feedback and update it.
Practical note: The goal of the first session is not to have a perfect canvas—but to have a canvas clear enough so you know what to test next. Entrepreneurship is a continuous learning process, not a one-time planning exercise.
BMC and the next step in your entrepreneurial journey
After completing the BMC, the natural next step is validate the most important assumptions — usually assumptions about customers and the value proposition. You can do this through customer interviews, testing an MVP (minimum viable product), or running a small trial before investing on a large scale.
BMC also provides a foundation for building other tools such as Value Proposition Canvas (exploring the customer–value relationship more deeply), or a financial model when raising capital. Treat the BMC as a map—not the destination.
Frequently asked questions
How many blocks does the Business Model Canvas have, and which is most important?
BMC consists of 9 blocks. No single block is absolutely “the most important,” but Value Propositions and Customer Segments are usually completed first because they shape the entire model. If these two blocks are wrong, the others will have little meaning.
Do New Entrepreneurs Need Financial Knowledge to Fill Out a BMC?
No advanced financial knowledge is needed. The Costs and Revenue boxes only require you to list cost types and ways of collecting money at a conceptual level. You will go deeper during financial modeling later.
How long does filling out a BMC take?
Your first attempt may take 60–90 minutes if you take it seriously. But the canvas truly “lives” through repeated updates—do not try to perfect it from the start.
Can I use the BMC for an online business model, or is it only for physical stores?
BMC applies to every type of business—physical stores, e-commerce, SaaS, consulting services, or platform models. How you fill it in varies by model, but the 9-block structure remains the same.
What is the difference between the BMC and a traditional business plan?
A traditional business plan is usually 10–50 pages long, takes weeks to write and is difficult to update. A BMC is a single page that can be completed in a few hours, is easy to revise and suits the early stage when everything is constantly changing.
