"Feasible" refers to something that is possible or easy to do, while "viable" means capable of working successfully or sustainably.
Feasible vs. Viable

Key Differences

"Feasible" implies practicality and the possibility of being accomplished, often within the context of available resources, knowledge, and technology. "Viable," on the other hand, focuses more on the capability of success or ongoing sustainability in the long term.

A feasible idea or plan is one that can be implemented without excessive difficulty or complexity. In contrast, a viable idea or plan not only can be implemented but is also likely to be successful or profitable in the future.

Feasibility often addresses the question, "Can this be done?" considering resources and constraints. Viability, however, asks, "Will this work over time?" considering factors like market demand, profitability, and long-term effects.

The assessment of feasibility is typically focused on the initial stages of a project or idea, evaluating whether it is practical to start. Viability assessment looks further into the future, evaluating whether the project or idea can maintain success or effectiveness.

A project can be feasible without being viable; it might be possible to start but not sustainable. Conversely, a viable project is usually also feasible, as its long-term success implies that it is practical and possible to initiate.
