Feasibility vs. Viability: What's the Difference?

Edited by Aimie Carlson || By Janet White || Updated on November 13, 2023
Feasibility assesses if something can be done, technically and legally. Viability examines if it should be done, based on long-term sustainability and profitability.

Key Differences

Feasibility refers to the practicality and possibility of a proposed project or system; it asks if the project can realistically be accomplished. Viability, on the other hand, goes a step further to analyze if the project will sustain itself in the long term, considering factors like profitability and market acceptance.
Feasibility studies often focus on the essential requirements of a project, including the availability of materials, technology, and human resources. In contrast, Viability studies are more concerned with the ongoing operational costs and the projected return on investment, ensuring the endeavor can maintain or grow its value over time.
Feasibility encompasses the investigation of legal and technical constraints facing a project, determining whether the project is achievable within these frameworks. Viability deals more with economic constraints, examining whether the project can meet its financial objectives and survive in the market.
Feasibility can also be seen as a snapshot at the starting line, clarifying whether a project is possible at the outset. Viability is the long race, contemplating the endurance of an initiative, considering market trends, competition, and financial projections.
Feasibility addresses the question, "Can we do it?" focusing on the practical aspects and immediate challenges of a project. Viability addresses the question, "Should we do it?" focusing on whether the project makes sense in the larger context and over an extended period.

Is a Feasibility study important?

Yes, it helps determine if a project is technically and legally possible before resources are committed.

How does market impact Viability?

Market trends, competition, and demand significantly impact a project's profitability and, hence, its Viability.

Can a project be feasible but not viable?

Yes, a project might be possible to initiate (Feasible) but may not be sustainable or profitable in the long term (Viable).

Why consider Viability?

To ensure the project can sustain itself, meet market demands, and be profitable over time.

What's a Viability study?

An analysis to determine if a business idea can sustain itself and be profitable in the long term.

Can Feasibility change over time?

Yes, as technology, laws, and resources evolve, the Feasibility of a project can change.

Do startups need Viability analysis?

Absolutely, to understand if their business model can survive and thrive in competitive markets.

How detailed should a Feasibility report be?

It should cover all essential aspects, including resources, technology, and legality, with enough detail to inform a decision.

Are Feasibility and Viability the same?

No, Feasibility assesses if something is possible, while Viability evaluates its long-term sustainability and profitability.

Who conducts Feasibility studies?

Experts with technical and legal knowledge relevant to the project, often third-party consultants.

How do investors use Viability studies?

To decide whether a business or project is worth investing in based on its long-term profitability.

What factors affect Feasibility?

Resource availability, technical constraints, and legal regulations primarily affect Feasibility.

Can Viability affect a brand's reputation?

Yes, a product's success or failure in the market can impact consumer perception and brand reputation.

Is Viability only about financial success?

Primarily, but it also considers other factors like market acceptance and competitive endurance.

Can Feasibility studies predict future obstacles?

They identify potential risks and bottlenecks at the project's outset, though not all future challenges.

When should Feasibility be assessed?

Before a project starts, to avoid investing in a project that's not possible technically or legally.

What's a technical Feasibility study?

It assesses whether the necessary technology and expertise are available to complete a project.

What if a Viability study results are negative?

It suggests re-evaluating the business model, strategy, or potentially abandoning the project to avoid future losses.

They can be, depending on the project's complexity, but they're valuable for informed decision-making.
