Turn a large market into a specific opportunity

A market can be large, growing and still unattractive for a particular business. The client may lack distribution, face strong substitutes or need more investment than the reachable demand can support.

Quick Prep’s Market Analysis focuses on defining the opportunity before estimating it, then connecting demand to customer behaviour, competition and economics. This preparation is useful for market sizing, growth, new-product, geographic expansion and market-entry cases.

The U.S. Small Business Administration’s market-research guidance considers demand, size, location, saturation, pricing and alternatives. Those categories are a useful research starting point; in interview practice, adapt them to the client’s decision. SBA: Market research and competitive analysis

Define the market boundary

Clarify the product or service, customer group, geography, channel and period. Specify whether you are estimating units, transactions, customers or revenue.

A market for urban takeaway coffee is different from the market for all coffee consumed in a country. A software estimate based on employees can differ greatly from one based on paying company accounts. Defining the unit early prevents an elegant calculation from answering the wrong question.

Distinguish a stock from a flow. The number of installed appliances is a stock; annual purchases are a flow influenced by replacement and new demand. You cannot equate the two without a purchase-cycle assumption.

If you use total addressable, serviceable and obtainable market concepts, explain what narrows each stage. Geographic reach, eligibility, distribution and capacity should create the boundaries. Applying arbitrary percentages can make the labels appear more rigorous than the analysis.

Build a transparent sizing model

A top-down model starts with a broad population and narrows it through relevant segments. A bottom-up model starts with individual units such as stores, customers or usage occasions and scales them.

Use both as a sense check when possible, but do not force agreement. Different results can reveal inconsistent scope or a weak assumption.

For a consumer product, a model might be eligible buyers × purchase frequency × units per purchase × realised price. For a business service, it might be eligible organisations × adoption × annual spend per customer. Segment where buying behaviour differs materially.

State which assumptions are conditional. For example, an adoption rate among qualified organisations should be applied after eligibility, while a rate measured across all organisations may already include that filter.

Worked exercise: size a commercial service opportunity

Illustrative interview exercise with fictional assumptions.

A provider is considering an equipment-maintenance subscription for small clinics in a region. There are 4,000 clinics. Assume 60% use the relevant equipment, giving 2,400 eligible clinics.

The annual package price is 2,000. At complete adoption, annual revenue opportunity within this defined eligible population is 4.8 million. This is not the provider’s forecast.

Suppose its initial service network can reach only 1,500 of the eligible clinics. At an assumed 20% adoption rate, it would serve 300 clinics and generate 600,000 in annual revenue once those subscriptions are fully active.

If annual contribution is 800 per customer and incremental fixed costs are 200,000, the plan produces 300 × 800 − 200,000 = 40,000 of operating profit before tax and any launch investment.

Operating break-even requires 250 customers, equivalent to approximately 16.7% of the 1,500 reachable clinics. The entry decision therefore depends heavily on whether adoption can exceed that threshold at the proposed price.

Next ask whether the provider can win those clinics, whether the service team can cover them and how quickly adoption ramps. The market estimate supports a decision only when those commercial and operational questions are connected.

Research the customer and the alternatives

Segment by needs and behaviour, not only demographics. In a business market, buying triggers, budget ownership, service requirements and procurement cycles may be more useful than company size alone.

Map direct competitors, substitutes and the option of doing nothing. A client can lose demand to an internal process, a cheaper workaround or delayed purchase. Competition is broader than companies with similar branding.

Assess what would cause a customer to switch. Consider price, performance, reliability, implementation effort, contracts and trust. A proposed benefit may matter little if the cost of changing is high.

For pricing, distinguish stated willingness to pay from observed behaviour. Interviews and surveys can inform a hypothesis, while experiments, transaction data and comparable offers may provide different evidence. Explain limitations instead of presenting one method as definitive.

Connect market attractiveness to entry feasibility

A complete entry recommendation combines demand, competitive advantage, contribution economics and execution. Estimate launch costs, acquisition effort, distribution needs and capacity, then test a downside.

Use ranges where uncertainty is material. If adoption could reasonably be 10% to 25%, show how that changes the recommendation. Identify the assumption that deserves the next research dollar: willingness to pay, conversion, service cost or retention.

Avoid double counting when adding segments. Customers can belong to several categories, and a marketplace’s transaction value is not automatically the platform’s revenue.

Practise a concise market argument

Choose an everyday product or business service. Define the scope in one sentence, build a sizing equation, make labelled assumptions and identify the three most important sources you would seek. Finish with a recommendation that explains whether the client can profitably reach the opportunity.

Use Industry Analysis to understand the surrounding value chain and Finance Modeling to model entry economics. The consumer goods and telecommunications primers provide useful contrasting applications. Contact Quick Prep to discuss your market-analysis preparation.

Frequently asked

What is the difference between market size and sales forecast?

Market size estimates total demand within a defined scope. A sales forecast estimates what a particular business can sell over a period, given its reach, conversion, capacity and competitive position.

What should I do when the interviewer provides no data?

Define the scope, propose a transparent model and make clearly labelled assumptions. Use rounded figures, test the most influential inputs and explain how you would validate them.

Should I always use TAM, SAM and SOM?

Use those labels when they clarify total demand, the serviceable portion and realistically obtainable business. The definitions and assumptions matter more than using the acronyms.
