A feasibility study answers one question. Should this project go ahead? Before you write a business plan, secure funding, or commit resources, a feasibility study tells you whether the idea is viable in the first place. It's the analysis you do before the plan, not after.
Too many founders skip straight to execution. They build the product, sign the lease, hire the team, then discover the market isn't big enough, the technology doesn't scale, or the unit economics don't work. A feasibility study catches these problems when fixing them costs nothing. After launch, it costs everything.
The four types of feasibility
Market feasibility
Is there enough demand? Who are the customers? How big is the addressable market? What do competitors charge? Market feasibility examines whether people will actually buy what you're planning to sell. It includes TAM/SAM/SOM analysis, customer interviews or surveys, competitor mapping, and pricing research.
Technical feasibility
Can you actually build it? Do the technology, skills, and infrastructure exist to deliver your product or service? Technical feasibility covers development requirements, technology stack decisions, scalability considerations, and any regulatory or compliance constraints on the technical implementation.
Financial feasibility
Do the numbers work? Financial feasibility models startup costs, ongoing expenses, revenue projections, break-even timelines, and ROI. This is where you discover whether a profitable business model actually exists within your cost structure and market pricing.
Operational feasibility
Can your organisation execute it? Operational feasibility examines team capabilities, process requirements, supply chain dependencies, and the day-to-day logistics of running the business. A technically feasible product with no viable supply chain is still infeasible.
When you need a feasibility study
Not every business idea needs a formal feasibility study. But some situations demand one:
- High capital investment. if the startup cost exceeds £50,000, validate before committing
- New market entry. entering a market you don't have experience in
- Novel technology. building something that hasn't been proven at scale
- Investor or grant requirements. many funding bodies require a feasibility study before considering applications
- Partnership decisions. evaluating whether a joint venture or strategic partnership makes financial sense
Feasibility study vs business plan
They're different documents with different purposes. A feasibility study asks "should we do this?" A business plan asks "how do we do this?"
The feasibility study comes first. If the answer is "yes, this is viable," then you write the business plan to map out execution. If the answer is "no," you've saved yourself months of work and potentially thousands in wasted capital.
Some founders combine them. That's a mistake. The feasibility study needs to be objective. The business plan is inherently optimistic (it's selling the idea). Mixing them contaminates the analysis.
Frequently asked questions
- How long should a feasibility study be?
- 10-30 pages depending on complexity. A small business feasibility study might be 10-15 pages. A large infrastructure project might require 50+ pages. Focus on depth of analysis, not length.
- Who writes a feasibility study?
- The founding team, a consultant, or a combination. For investor or grant submissions, having an independent third party conduct or review the study adds credibility. For internal decision-making, doing it yourself is fine.
- What does a bankable feasibility study mean?
- A bankable feasibility study meets the standards required by banks and financial institutions for loan approval. It includes independently verified market data, conservative financial projections, risk analysis with mitigation strategies, and professional formatting.
