Feasibility Studies
Pre-Feasibility Study
A pre-feasibility study answers an earlier and more economical question than a full feasibility study: is this concept strong enough to justify deeper investigation? It screens the proposition for fatal flaws, weak demand assumptions, unrealistic project economics and critical information gaps before management commits the time and cost required for a full study.
The objective is not to reach false precision with limited data. It is to identify what is already knowable, what could stop the project, which alternatives deserve comparison and what evidence must be obtained before the next decision gate.
When pre-feasibility is the right first step
A pre-feasibility study is useful when the opportunity is still being shaped. Typical situations include:
- the concept is promising but important assumptions remain undefined;
- several sites, capacities or operating models are still possible;
- management wants to screen an opportunity before approving a larger research budget;
- reliable market or technical data is limited;
- early capital estimates have a wide range;
- the business model has not yet been validated against customer demand;
- a major dependency may make the concept impractical; or
- an investment committee wants an initial decision memo before authorising full diligence.
A full feasibility study is usually more appropriate once the project is sufficiently defined and management is approaching a material capital, site, financing or implementation decision.
The fatal-flaw screen
The first job is to identify issues that could make further analysis unnecessary unless they are resolved.
Potential fatal flaws vary by project. Examples include insufficient addressable demand, an inaccessible site, a critical input that cannot be secured, an operating model that cannot reach the proposed capacity, a cost base inconsistent with market pricing, a regulatory dependency that changes the project structure, or a capital requirement materially above the sponsor’s investment envelope.
The screen should not label an issue “fatal” merely because it is difficult. The distinction is whether the issue can reasonably be redesigned, mitigated or evidenced. A project with a solvable weakness may move to a revised concept; a project whose fundamental economics cannot work should not absorb a full-study budget simply to confirm the same conclusion in more detail.
Preliminary market test
At pre-feasibility stage, the market work should be proportionate but decision-relevant. The aim is to determine whether there is enough evidence of demand to keep the concept alive and which market assumptions require deeper validation.
The initial review can examine:
- target customer and use case;
- broad addressable demand;
- existing alternatives and competitors;
- indicative pricing;
- current supply or capacity;
- customer-access channels;
- major demand drivers; and
- the implied market share required by the concept.
If the preliminary financial case requires a level of market capture that is already implausible, that is a valuable early finding. If demand appears credible but uncertain, the study should define the primary research or data required during full feasibility.
Preliminary operating and technical screen
The concept also needs an early delivery test. The pre-feasibility review should identify the main operating requirements and dependencies without pretending to replace detailed technical work.
Depending on the project, this can include site requirements, indicative capacity, major equipment or technology, utilities, labour, supplier or feedstock requirements, logistics, implementation lead times and material licensing or approval dependencies.
Where engineering design, environmental assessment, legal interpretation or specialist certification is required, the pre-feasibility study should identify that need and its effect on the next stage. It should not imply that general commercial analysis has resolved a specialist technical question.
Preliminary project economics
The early financial model should be simple enough to reflect uncertainty and detailed enough to reveal whether the economics have a plausible path.
Typical inputs include:
- indicative capital expenditure;
- broad operating cost;
- preliminary price and volume assumptions;
- working-capital considerations;
- estimated ramp-up;
- approximate cash requirement; and
- early break-even or return indicators where meaningful.
Ranges are often more honest than point estimates at this stage. The model should show which inputs are estimates, which have external evidence and which are management assumptions.
The purpose is not to approve the investment. It is to test whether a credible economic case exists and identify the variables that deserve more precise work.
Compare options before narrowing the project
Pre-feasibility is particularly valuable when the project has not yet converged on one configuration.
Alternative cases may compare:
- locations;
- project sizes or capacity;
- phased versus single-stage development;
- build versus lease;
- in-house versus outsourced components;
- customer segments;
- technology or operating approaches; or
- different implementation dates.
The comparison need not contain full models for every option. It should be sufficient to eliminate weak alternatives and identify the configurations worth carrying into full feasibility.
Build the data-gap register
A high-quality pre-feasibility study should finish with a clear record of what is not yet known.
The data-gap register can classify each unresolved issue by:
- the question to be answered;
- why it matters to the decision;
- the current assumption;
- the evidence required;
- the responsible source or specialist;
- the cost or effort to obtain the evidence; and
- the decision stage by which it must be resolved.
This turns uncertainty into a work plan. It also prevents a full feasibility study from spending time rediscovering the same missing information.

Decision gates
The output should define a clear next gate rather than end with “more research is needed”.
Proceed to full feasibility
when the concept has no unresolved fatal flaw, the preliminary demand and economics are credible enough to justify deeper work, and the remaining uncertainties can be investigated.
Revise and rescreen
when the opportunity may be attractive but the current site, scale, business model, cost structure or another core assumption needs to change first.
Stop
when evidence already indicates that the concept is structurally weak or an essential dependency is not realistically resolvable.
Hold
may be appropriate when a specific external event, approval, data source or market condition must be resolved before further expenditure makes sense.
Methodology and evidence
A disciplined pre-feasibility process can follow six steps:
1. Define the concept and decision. Clarify what is known, what remains open and what management is deciding now.
2. Run the fatal-flaw screen. Identify constraints that could invalidate the proposition.
3. Test the preliminary market case. Assess demand, competition, price and the scale of customer capture required.
4. Screen operating and technical requirements. Identify capacity, site, resources, technology and specialist dependencies.
5. Build preliminary economics. Estimate capital, operating cost, revenue and cash requirements using transparent ranges and assumptions.
6. Issue the decision memo and data-gap plan. Recommend full feasibility, revision, hold or stop, with the evidence required for the next gate.
This staged logic is consistent with established feasibility practice: early screening should reduce uncertainty and eliminate weak options before resources are committed to detailed appraisal.
What the client receives
A pre-feasibility package can include:
- executive pre-feasibility decision memo;
- fatal-flaw screen;
- preliminary market and competitor assessment;
- preliminary project economics;
- initial operating/technical requirements;
- option comparison where relevant;
- critical assumptions register;
- data-gap and research plan;
- priority risks; and
- recommendation on whether and how to proceed to full feasibility.
The output should make the next piece of work smaller and more precise, not simply defer every question.

Frequently asked questions
What is the difference between pre-feasibility and a full feasibility study?
Pre-feasibility is an early screening exercise designed to identify fatal flaws, compare broad options, test preliminary market/economic logic and define evidence gaps. A full feasibility study is deeper and is normally used once the project is sufficiently defined for a material investment or implementation decision.
What information is needed at the pre-feasibility stage?
A clear concept is more important than complete data. Useful inputs include the proposed product or service, target customer, possible location, indicative scale, expected pricing, rough capex, operating assumptions, known technical requirements, existing research and the sponsor’s decision constraints.
How are fatal flaws identified?
The study tests dependencies that could make the concept unviable even before detailed modelling—for example, implausible demand, unavailable critical inputs, an unsuitable site, an operating constraint, a severe cost-price mismatch or a non-resolvable approval dependency. Each issue is assessed for whether it can be redesigned or requires the concept to stop.
When should a full feasibility study be commissioned?
When the preliminary case remains credible, the project has been narrowed to a workable configuration and the unresolved questions justify deeper market, technical and financial work. The pre-feasibility recommendation should state exactly which evidence the full study must resolve.
