Developing a Business Idea Using the Business Model Canvas
Lesson 4 of 4
25 min

A canvas is built on a large sheet, often with sticky notes so that ideas can be moved, removed and argued about. Each block has its own options. The table gives the main ones; knowing them helps you fill the canvas with precise answers instead of vague ones.
| Block | Meaning | Main types or options |
|---|---|---|
| Customer segments | the groups of people or organisations the business serves | mass market; niche market; several segments; multi-sided (two groups that need each other) |
| Value propositions | the benefits that make each segment choose the business | newness; better performance; lower price; convenience; design; reducing a cost or a risk; access |
| Channels | how the business makes customers aware, sells, delivers and gives after-sales service | own channels (shop, sales staff, website); partner channels (wholesalers, retailers, agents) |
| Customer relationships | the kind of relationship the business builds with each segment | personal assistance; self-service; automated service; communities; co-creation with customers |
| Revenue streams | the ways each segment pays | sale of goods; usage fee; subscription; rent; licence fee; commission; advertising |
| Key resources | the most important assets needed | physical; human; financial; intellectual (brands, recipes, designs) |
| Key activities | the most important things the business must do | production; problem solving for clients; running a platform or network |
| Key partners | the suppliers and partners that make the model work | suppliers; alliances with non-competitors; joint ventures; cooperation with competitors |
| Cost structure | the most important costs of running the model | fixed and variable costs; cost-driven (cheapest possible) or value-driven (quality first) |
Definition
Niche market: a small, specific customer segment with special needs, such as boarding schools that buy food in bulk. Mass market: a large group of customers with broadly similar needs, served in the same way.
Assumption: something believed to be true about a business, such as a price customers will pay, that has not yet been tested.
Tip
Right side first, then left, then the bottom. Begin with customers and value (the right side), then what you need to deliver it (the left), then the money (the bottom). Use one colour of sticky note per customer segment, so you can see which value, channel and revenue belong to which group.
Worked example 1: Ishimwe’s finished canvas
Checking the fit: each segment has a value proposition and a channel (families buy at grocery shops; restaurants and boarding schools order by phone at a bulk price). The market sellers are both a key partner and the reason the value proposition “less waste” is true. The revenue of Frw 1,000 a packet must cover the costs in the bottom-left box; lesson 3 showed she breaks even at 184 packets a month. The case is illustrative.
Worked example
Worked example 2: testing an assumption (illustrative figures)
Ishimwe’s most important assumption is that she can sell 300 packets a month. She tests it: in two weeks, two grocery shops sell 110 packets.
Monthly rate: packets a month.
Compare: 220 is above her break-even of 184 but below her target of 300, a shortfall of packets.
Revise the canvas: two restaurants asked for bigger bags, so she adds a 1 kg bulk bag (value proposition), lists restaurants and boarding schools more clearly (customer segments) and adds phone orders (channels). She also lowers her sales forecast in the business plan until the new channels prove themselves.
Warning
Common mistakes. (1) Filling the left side first, then looking for customers to fit. (2) Vague notes such as “good quality” or “everybody”: write who exactly, and what exactly. (3) Never testing: a canvas that has not met a real customer is only a guess.
