Business Ideas and Opportunities
Lesson 1 of 4
25 min
In 2023 Ishimwe planned a phone-charging kiosk for a village in Nyaruguru District that had no electricity. Villagers walked to the sector office to charge their phones and paid for it. The idea was sound and the need was real. He saved for a solar panel and a battery, but by the time he had the money, in 2025, the village had been connected to the grid. Most homes now charged their phones for almost nothing. The kiosk opened and closed within four months.
His classmate Keza had a less exciting idea: selling cooked beans and rice to the builders working on a new health centre nearby, for the eighteen months the work would last. She started within two weeks, with one pot and a cool box. (Illustrative case: the people and details are invented.)
Think about it: Ishimwe's idea was good. Why did it fail, when Keza's ordinary idea succeeded?
These three words are often used as if they meant the same thing. In entrepreneurship they mean three different steps.
Definition
Business: an organised activity in which a person or group produces or buys goods, or provides services, and sells them to customers, usually with the aim of making a profit. Every business combines an owner who takes the risk, a product, customers, and resources such as money, skills, equipment and time.
Example: Keza's food stall: she buys beans and rice, cooks them, and sells meals to builders for more than they cost her.
Definition
Business idea: a thought or proposal about a product or service that could be sold to customers to earn money. An idea exists in the mind or on paper; nobody has yet checked whether it can work.
Example: "I could charge people's phones with a solar panel."
Definition
Business opportunity: a business idea that is backed by a real, unmet need of customers who are able and willing to pay, at a time when the entrepreneur can act on it with the resources available and make a profit. An opportunity is an idea that fits the market now.
Example: builders on a site with no canteen, who need lunch every day for eighteen months.
| Point | Business idea | Business opportunity |
|---|---|---|
| Where it starts | The entrepreneur's mind | The market: a need that customers have |
| Evidence | None yet: a possibility | Customers, demand and profit can be shown |
| Timing | Not considered | Must be acted on while the window is open |
| Resources | Not yet matched | The entrepreneur can obtain what is needed |
| How many | Many | Few: most ideas are not opportunities |
Every opportunity starts as an idea, but most ideas are not opportunities. Jeffry Timmons, an American professor of entrepreneurship, summed up a good opportunity as one that is attractive (customers want it), durable (it lasts long enough to earn a return), timely (the moment is right), and anchored in a product or service that creates or adds value for the buyer.
Opportunities do not last for ever. A window of opportunity is the period during which an opportunity can be taken profitably. It opens when a need appears and closes when competitors fill the market, the need disappears, or something cheaper replaces the product.
Tip
The opportunity test in one sentence: "Who will pay, how much, how many of them are there, why now, and can I do it?" If you cannot answer all five, you still have an idea, not an opportunity.
Worked example 1: is the opportunity big enough?
Keza estimates that 45 builders work on the site, that 60% of them will buy her lunch on a working day, that a plate sells for Frw 800, and that each plate costs her Frw 500 to make. There are 22 working days a month and the work will last 18 months. Estimate her monthly gross profit and the total over the life of the window. (Illustrative figures.)
Plates sold per day:
Gross profit per plate, per day and per month:
Over the whole window:
Interpretation: a window that is open for only 18 months can still be worth over Frw 3 million in gross profit, because Keza needed almost no capital and started quickly. A short window rewards a fast, low-cost start.
Worked example 2: idea or opportunity?
Warning
A good idea is not the same as a good opportunity. Students often judge an idea by how new or exciting it is. Customers judge it only by whether it solves their problem at a price they can pay, at the time they need it.
Jennifer David of Stonecircle Consulting explains the difference between a business idea and a business opportunity. Listen for the questions she asks to test whether an idea is an opportunity, and compare them with the five-question test above.
