Career fields in entrepreneurship

Where people work for themselves

Most people who run their own small business in Rwanda work in the informal sector: small, unregistered businesses. NISR's Labour Force Survey Annual Report 2024 shows which industries those workers were in.

Think about it: almost half of the informal sector is farming for the market. What does that tell you about where the most customers, and the most competitors, are? Which of the smaller fields might be growing?

Definition

Career field: a broad area of economic activity that contains many related occupations and businesses, such as agribusiness, construction or ICT. An entrepreneur chooses a field, then a niche: a narrow part of it that serves a particular group of customers.

Example: in the field of ICT, a niche is repairing and refurbishing laptops for secondary-school students.

Definition

Informal sector: the part of the economy made up of small businesses that are not registered and do not keep formal accounts. Value chain: the full sequence of activities that turn raw materials into a product in the hands of the final buyer, each stage adding value; every stage is a field for entrepreneurs.

The main fields and what entrepreneurs do in them

Field	Examples of ventures	Skills that help
Agriculture and agribusiness	Vegetable or poultry farming, selling seeds and feed, veterinary services, crop storage	Agronomy or animal health, record keeping, marketing
Manufacturing and agro-processing	Milling, juice and dairy processing, soap, furniture, tailoring	Technical trade, hygiene and quality control
Construction	Masonry and carpentry contracting, bricks and blocks, plumbing, electrical installation	Trade skills (often from TVET), estimating, safety
Trade	Retail shops, wholesale, cross-border trade, online selling	Buying, pricing, stock control, customer care
Transport and logistics	Moto and car transport, delivery, cold-chain transport	Licences, route planning, vehicle maintenance
ICT and digital services	Phone and computer repair, web design, software, digital marketing	Programming, repair, design, online communication
Tourism, hospitality and food	Restaurants, guest houses, tour guiding, events	Languages, customer service, food safety
Creative industries	Fashion, crafts, music, film, photography	Artistic skill, branding, copyright knowledge
Services to people and businesses	Hair and beauty, tutoring, cleaning, accounting, mobile-money agencies	Professional skill, trust, reliability
Energy and environment	Solar installation, briquettes, recycling, compost	Technical training, sales

One value chain, many careers

A field is easier to understand as a chain. Coffee, one of Rwanda's best-known exports, passes through several stages between the farm and the cup, and each stage is run by entrepreneurs, cooperatives or companies.

Tip

Look up and down the chain. If a field is crowded at one stage (many farmers growing the same crop), the opportunity may be at the stage just before it (supplying them) or just after it (processing, storing or transporting what they grow).

Worked example 1: reading the chart

Use the NISR figures in the chart. (a) What share of informal-sector workers were outside agriculture? (b) How many times larger was agriculture's share than manufacturing's?

(a)

100\% - 48\% = 52\%

(b)

\frac{48}{5.4} \approx 8.9

Interpretation: slightly more than half of informal-sector workers were outside farming, and for every worker in informal manufacturing there were almost nine in market-oriented agriculture. A young entrepreneur reads this two ways: agriculture has the most customers and suppliers, but manufacturing, where few people work, may face less competition for the same skills.

Worked example 2: value added by a small roaster

A young roaster in Huye buys 100 kg of green (unroasted) coffee at Frw 6,000 per kg. Roasting loses 15% of the weight. She sells the roasted coffee in 250 g packs at Frw 3,000 each. Packaging, fuel and transport cost Frw 180,000. Find the value she adds and her profit. (Illustrative figures.)

Cost of green coffee and mass after roasting:

100 \times 6\,000 = 600\,000 \ \text{Frw}, \qquad 100 \times (1 - 0.15) = 85 \ \text{kg}

Packs and revenue (1 kg = 4 packs of 250 g):

85 \times 4 = 340 \ \text{packs}, \qquad 340 \times 3\,000 = 1\,020\,000 \ \text{Frw}

Value added and profit:

\text{Value added} = 1\,020\,000 - 600\,000 = 420\,000 \ \text{Frw}, \qquad \text{Profit} = 420\,000 - 180\,000 = 240\,000 \ \text{Frw}

Interpretation: the roasting stage turns Frw 600,000 of coffee into Frw 1,020,000 of sales. Moving one stage along a value chain is one of the most common ways for an entrepreneur in agriculture to earn more from the same crop.

Warning

Do not choose a field only because it is big. The biggest field also has the most competitors. Choose where your interests and skills meet a gap: a stage of a value chain that is missing or badly served in your area.

WOSU Public Media, "Coffee - From Farm to Cup: QED with Dr. B". Follow the stages from the farm to the cup and, for each one, name the kind of business that does that work.

Practice

Define career field, niche and value chain.
Name six career fields in entrepreneurship and give one venture in each.
From the NISR chart, list the industries in order of their share of informal-sector workers in 2024, largest first.
From the chart, calculate the combined share of construction, transport and storage, and manufacturing.
Draw the value chain for milk, from the farm to the consumer, and name one entrepreneurial career at each stage.
A miller buys 500 kg of maize at Frw 400 per kg. Milling gives flour equal to 80% of the maize weight, sold at Frw 750 per kg. Calculate the value added by milling.
Which career field would you choose, and at which stage of its value chain? Justify your choice using your interests, skills and local demand.

Career field: a broad area of activity with many related occupations and businesses. Niche: a narrow part of a field serving a particular group of customers. Value chain: the sequence of activities that turn raw materials into a product for the final buyer, each stage adding value.
Any six with sensible examples, e.g. agribusiness (poultry farm), manufacturing (soap making), construction (block making), trade (retail shop), transport (delivery service), ICT (phone repair), tourism (guest house), creative industries (fashion design).
Market-oriented agriculture (48%), trade and vehicle repair (15.6%), construction (11%), transport and storage (7.7%), manufacturing (5.4%); the other industries together were 12.3%.
$11 + 7.7 + 5.4 = 24.1\%$ .
Example: inputs (feed, veterinary drugs: agro-vet shop owner) → dairy farming (farmer) → collection (milk collection centre operator) → processing (dairy processor) → distribution (cold-chain transporter) → retail (milk bar owner).
Cost $= 500 \times 400 = 200\,000$ Frw. Flour $= 0.80 \times 500 = 400$ kg. Revenue $= 400 \times 750 = 300\,000$ Frw. Value added $= 300\,000 - 200\,000 = 100\,000$ Frw.
Answers vary; a good answer names a field and a stage, links them to the student's interests and skills, and gives evidence of local demand or a gap.

Quick check

According to NISR, which industry had the largest share of informal-sector workers in Rwanda in 2024?

Key points

Entrepreneurs work in every field: agribusiness, manufacturing, construction, trade, transport, ICT, tourism, creative industries, services and energy.
In 2024, 48% of Rwanda's informal-sector workers were in market-oriented agriculture, followed by trade (15.6%), construction (11%), transport (7.7%) and manufacturing (5.4%) (NISR).
A value chain shows the stages from raw material to buyer; each stage is a niche, and value added = sales − cost of inputs bought.
Choose where your interests and skills meet a gap, not just the biggest field.
