The Business Model Canvas (SACE Stage 2 Business Innovation)
“Use the Business Model Canvas to map and evaluate how a business creates, delivers and captures value.”
The Business Model Canvas (BMC) is a one-page tool with nine building blocks that shows how a business creates, delivers and captures value. You use it to map your venture, check the blocks fit together, and spot weak assumptions to test.

What this dot point is asking
You need to be able to complete a Business Model Canvas for your own idea and explain how the blocks connect - especially how the revenue side covers the cost side.
The nine building blocks
The canvas is usually drawn with the customer-facing blocks on the right and the operations blocks on the left.
- Customer segments - the specific groups you serve. Be precise, not "everyone".
- Value proposition - the bundle of products and services that solve a customer problem or meet a need.
- Channels - how you reach and deliver to customers (online store, social media, retail, direct).
- Customer relationships - how you get, keep and grow customers (personal service, self-service, community, subscriptions).
- Revenue streams - how the business earns money (one-off sales, subscriptions, licensing, advertising).
- Key resources - the assets you must have (people, equipment, IP, finance).
- Key activities - the most important things you must do (production, problem-solving, platform management).
- Key partnerships - suppliers and partners who help you operate.
- Cost structure - the major costs, split into fixed and variable.
The rationale for how an organisation creates, delivers and captures value. The Business Model Canvas makes this rationale visible on a single page.
How the blocks fit together
The canvas is only useful if the blocks are coherent. The value proposition must match the customer segment's needs. The channels and relationships must suit that segment. The key resources, activities and partnerships must be the ones needed to deliver the value proposition. And crucially, the revenue streams must exceed the cost structure for the model to be viable.
The right side of the canvas is about value and customers (segments, value proposition, channels, relationships, revenue). The left side is about efficiency and operations (resources, activities, partnerships, costs). A strong model balances both.
Using the canvas to test and refine
The canvas is a thinking tool, not a finished plan. Each block contains assumptions. List them, then prioritise the riskiest to test with real customers before committing money. A canvas should change as you learn - an early version and a refined version is exactly the evidence markers reward.
A student's refill-station venture maps as: customer segments = local sports clubs; value proposition = cut plastic waste and bottle costs; channels = direct sales plus club newsletters; revenue streams = monthly subscription per club plus sponsor fees; key resources = filter units and a van; key activities = installation and refills; key partnerships = a filter supplier and a sponsor; cost structure = unit cost, fuel, maintenance. Mapping it reveals the riskiest assumption - that clubs will pay a recurring subscription - which becomes the first thing to test.
Evaluating the model
To evaluate a canvas, ask: Is the value proposition clearly desirable to a defined segment? Are revenue streams realistic and larger than costs? Are the key resources and partnerships actually obtainable? Where are the untested assumptions? Strong analysis identifies the weakest block and proposes how to strengthen or validate it.
Treating the canvas as nine disconnected lists. The marks are in the connections. Always explain how, for example, your chosen channel suits your segment, or how your revenue streams cover your cost structure. A canvas where revenue cannot cover costs is not viable, however neat the boxes look.
The canvas versus the lean canvas
SACE students often meet a variant called the Lean Canvas, adapted by Ash Maurya for early-stage start-ups. It replaces four of the original blocks (key partnerships, key activities, key resources and customer relationships) with problem, solution, key metrics and unfair advantage. The standard Business Model Canvas suits describing and evaluating an existing or well-understood business, because it foregrounds operations and infrastructure. The Lean Canvas suits a brand-new venture facing high uncertainty, because it forces you to state the customer problem and the riskiest assumptions first. Knowing why each tool exists, and choosing the one that fits the stage of your venture, is the kind of evaluative judgement that lifts a Business Innovation response.
Linking forward
The canvas underpins your financial modelling (cost structure and revenue streams feed cash flow), your testing plan (riskiest assumptions), and your pitch. It is central to both the Business Growth Report and the external Business Plan.
Assessment-style questions
Questions on this dot point, each with a worked answer, written by ExamExplained. Business Innovation has no written exam, so use them to check your understanding before your assessment tasks.
Practice4 marksIdentify the nine building blocks of the Business Model Canvas and explain how the right-hand side of the canvas differs in purpose from the left-hand side.Show worked answer →
The nine blocks are customer segments, value proposition, channels, customer relationships, revenue streams, key resources, key activities, key partnerships and cost structure.
The right-hand side (segments, value proposition, channels, relationships, revenue streams) is about value and the customer: who is served, what value is offered, how it reaches them and how the business earns. The left-hand side (key resources, activities, partnerships, cost structure) is about efficiency and operations: what the business needs and does to deliver that value, and what it costs.
A strong answer names all nine blocks correctly and explains the value-versus-efficiency split, ideally noting that the model is viable only when the revenue side exceeds the cost side. Markers reward the correct allocation of blocks to each side, not just a list.
Practice6 marksFor a venture of your choice, complete a Business Model Canvas and evaluate which single building block carries the riskiest assumption, justifying how you would test it.Show worked answer →
A high-band response maps a coherent canvas for one defined venture (for example a campus bike-repair service), filling all nine blocks with specific, connected entries rather than generic lists.
The evaluation then isolates one block where the model is most likely to fail. For a subscription-based venture this is usually the revenue streams block (will customers actually pay a recurring fee?) or the value proposition (is the problem painful enough to pay for?). The answer justifies the choice by explaining why that assumption, if wrong, would collapse the rest of the canvas.
Finally it proposes a concrete, low-cost test, such as pre-selling memberships or running a smoke test landing page, with a clear success metric. Markers reward a coherent canvas, identifying a genuinely critical assumption (not a trivial one), and a realistic validation method with a measurable signal.
