The debate between shareholder primacy and stakeholder theory concerns the legal obligations of corporate directors. Introduction A corporation is never just a machine for making money. It is a legal institution, a social system, and a vehicle for allocating power, risk, and responsibility. That is why one of the most important debates in corporate governance continues to divide scholars, executives, regulators, and investors: should corporations exist primarily to maximize shareholder value, or should they balance the interests of all the people and institutions affected by their actions? This debate is commonly framed as shareholder primacy vs. stakeholder theory. Shareholder primacy says the corporation's central obligation is to its owners, the shareholders. Stakeholder theory says the corporation owes duties to a wider circle of affected parties, including employees, customers, suppliers, creditors, communities, and sometimes society at large. This is not a purely academ...
This post is about opportunity assessment, the process of testing whether a business idea is worth pursuing before capital is committed. It covers the criteria every opportunity must satisfy, the difference between an idea and an opportunity, and the screening sequence that filters weak proposals out. The post tests the method against Airbnb’s early growth in San Francisco and M-PESA’s launch at Safaricom in Kenya.

Opportunity assessment: three tests that decide whether to proceed.
Table of Contents
An Idea Is Not an Opportunity
Definition
Opportunity assessment is the process of testing whether a business idea meets the conditions required to become a viable venture. Jeffry Timmons, writing in New Venture Creation, first published in 1974, defined an opportunity as a situation in which a product or service can be introduced at a price that covers all costs and produces a profit, and in which the market, the team, and the resources are aligned.
The distinction between an idea and an opportunity rests on three conditions:
- Attractive — the opportunity must offer value to a buyer, at a price the buyer will pay.
- Durable — the opportunity must last long enough to repay the investment, usually three to five years.
- Timely — the opportunity must be available now, not in a market that does not yet exist.
My reading of the evidence is that most failed ventures were never opportunities at all. They were ideas that the founder mistook for opportunities because the founder found them interesting. Interest is not a market.
An idea becomes an opportunity when it passes four sequential tests:
- Market test — a specific group of customers with a specific problem exists and has money to spend.
- Capability test — the founder or team can deliver the product with the resources they can access.
- Economic test — the price the customer will pay exceeds the total cost of delivery.
- Timing test — the market is ready now, not in three years or in a market that has already passed.
The interpretive point is that an opportunity is a fact about the world, not a belief held by the founder. If the founder cannot show the evidence that the four tests pass, the idea remains an idea.
The Four Criteria Every Opportunity Must Satisfy
Definition
The criteria for assessing an opportunity were set out by Howard Stevenson at Harvard Business School and refined by Timmons. The standard framework holds that an opportunity must be attractive, achievable, durable, and value-creating, and that a weakness in any one criterion disqualifies the venture.
The four criteria, in the form the framework requires, are these:
- Market demand — evidence that a defined group of customers will pay for the solution.
- Market size and growth — a market large enough to support the venture, and growing fast enough to reward early entry.
- Margin potential — a gross margin high enough to cover fixed costs and still return a profit.
- Fit with the team — the skills, networks, and experience the founders bring to the venture.
I will put it this way: the four criteria are not equally weighted. Market demand is decisive. A team with average skill and strong market demand will usually beat a team with strong skill and weak market demand. Key point: the first question in any opportunity assessment is not “can we build it” but “will they buy it.”
The four criteria are tested through three sources of evidence:
- Primary research — interviews and surveys with real potential customers.
- Secondary research — published market reports, industry data, and government statistics.
- Analogous evidence — the performance of similar ventures in comparable markets.
The insight to carry forward is that a criterion without evidence is an opinion. The assessment is only as strong as the evidence behind each of the four criteria, and the weakest criterion is the one that decides whether the venture proceeds.
Case Study
Airbnb and M-PESA illustrate opportunity assessment from opposite ends of the market. Airbnb tested an opportunity in an established market, short-term accommodation, and won by offering a new channel. M-PESA tested an opportunity in a market that most observers believed did not exist, banking for unbanked adults, and won by offering a service that had never been available.
Airbnb launched in 2007 when founders Brian Chesky and Joe Gebbia rented three air mattresses in their San Francisco apartment during a sold-out design conference. The initial test cost almost nothing and returned revenue the same weekend. Airbnb reported 4 million guests in 2015, 150 million in 2018, and over 2 billion cumulative guest arrivals by 2024 in its annual reports. M-PESA launched at Safaricom in 2007 with a value proposition no Kenyan bank had offered: send money by mobile phone without a bank account. The customer segment was the unbanked adult population. The channel was the existing Safaricom SIM and agent network. The economic test was a small transaction fee per transfer. By 2015 M-PESA had become the largest mobile-money service in the world by volume outside traditional banking, and Safaricom’s annual reports credit it as the largest single contributor to service revenue. [VERIFY: confirm the current M-PESA revenue-share figure and year against Safaricom’s most recent annual report.]
Airbnb and M-PESA prove the same point from different positions. Airbnb succeeded because the market test was answered with a single weekend of evidence: three paying guests. M-PESA succeeded because the market test was answered by a customer segment that already existed and already paid for a worse alternative, which was cash carried over long distances. In both cases, the founder did not wait to prove the market with a formal study. The founder ran the smallest possible test that produced real evidence. Opportunity assessment is not a study. It is a test, and the test must produce evidence a stranger can check.
The Screening Sequence That Filters Weak Proposals
Definition
Screening is the process of eliminating opportunities that fail the criteria before capital or time is committed to them. Timmons set out the screening approach as a fixed sequence in which every opportunity is tested against the same criteria, in the same order, and eliminated at the first failure.
The two stages of screening are these:
- First-pass screening — a rapid filter against the criteria, completed in a single session.
- Detailed assessment — a full analysis of the survivors, requiring research and evidence.
The screening sequence must be ordered. A proposal that fails the market test is eliminated before the team test is applied, because the team test is more expensive to run and no amount of skill can rescue a market that does not exist. The order is what makes screening efficient.
The five principles I recommend for any screening process are these:
- Fix the criteria before seeing the proposals — criteria set after the fact are shaped by the outcome.
- Apply the criteria in the same order to every proposal — inconsistency invalidates the comparison.
- Eliminate at the first failure — a proposal that fails one criterion should not be carried forward on the strength of another.
- Record the reason for elimination — a written reason allows the same idea to be re-screened when conditions change.
- Rescreen quarterly — a market that failed last quarter may pass this quarter if the technology or regulation has moved.
The closing insight is that screening is a discipline of rejection. A team that accepts most of the proposals it screens is not screening. It is approving.
The Feasibility Test and the Economic Test
Definition
The feasibility test determines whether the venture can actually be built with the resources available to the founders. The economic test determines whether the venture can return more money than it consumes. Together they form the final gate before an opportunity becomes a business plan.
The feasibility test is not a question of whether the product is possible in principle. It is a question of whether the founder can produce it with the time, money, and skill actually available. A product that requires ten million United States dollars and three years to build is not feasible for a solo founder with two hundred thousand dollars and six months of runway, even if the market is real.
The three-element framework I recommend for the final gate is this:
- Resource feasibility — the capital, people, and time required to reach first revenue, compared against what the founder controls.
- Unit economics — the revenue per customer, the cost to acquire that customer, and the gross margin per transaction.
- Break-even analysis — the number of customers or units required to cover fixed costs, expressed in months from launch.
The section closes with the recommendation that the feasibility and economic tests be written on a single page, using the best available evidence, before any capital is committed. A venture that has passed the market and capability tests but cannot state its break-even point has not finished the assessment. It has only completed the easy half, and the second half is the one that decides whether the venture survives.
Conclusion
The case evidence establishes that opportunity assessment is a filter, not a formality. Airbnb and M-PESA both passed the four criteria before scaling, and both did so with evidence gathered from a small, cheap test rather than a long study. The assessment was decisive because it happened before capital was spent, not after.
Opportunity assessment matters because most ventures fail for reasons that could have been seen at the screening stage, and the assessment is the last point at which the founder can walk away without cost. The process is supposed to produce four outputs: an evidence-based market test, a capability test that names the founder’s real resources, an economic test that states the break-even point, and a written decision to proceed or reject. It applies at the start of every new venture, at every pivot, and at every acquisition or partnership decision where a new market is being considered. The people responsible are the founder and the venture team, with the finance lead owning the economic test and the operations lead owning the feasibility test. The method is to fix the criteria in advance, apply them in the same order to every proposal, eliminate at the first failure, and record the reason for elimination in writing. The advantage of this discipline is that it prevents the founder from committing years of effort to a market that does not exist, that it produces evidence an investor can review, and that it forces the team to name the weakest criterion before the market does. The limitation is that screening depends on the accuracy of the criteria, that a market that fails today may pass tomorrow, and that a strong screen cannot rescue a founder who lacks the execution discipline to build what the screen approved.
The recommendations I would give any founder or venture team conducting an opportunity assessment are these:
- Write the four criteria before screening any proposal — criteria set after the fact are shaped by the outcome.
- Run the smallest test that produces real evidence — a weekend pilot with three paying customers beats a three-month market study.
- Test the market before the team — no amount of skill can rescue a market that does not exist.
- State the break-even point in months — an assessment that does not name when the venture repays its costs is incomplete.
- Record the reason for every rejection — a written reason allows the same idea to be re-screened when conditions change.
An opportunity assessment is only as strong as the evidence behind its weakest criterion, and the discipline of rejecting proposals is the whole of the exercise.
