A simple and crystal clear way to distinguish:

  • Capability determines WHETHER a person or organization can offer a certain product or service.
  • Capacity determines HOW MUCH of this service or product can be offered within a defined time frame

Hence, capability ensures that you can get going, and capacity ensures that you can meet the demand that you face.

Capability is a broad definition that refers to the differentiators the company can have:

  • Cheap suppliers
  • Intellectual property
  • Unique contracts with distributors
  • Economies of scale
  • Talent
  • Etc

Capacity usually refers to how much the company can produce. If the company has more capacity than anyone else on the market it's also a unique capability

first, I wouldn't necessarily speak of concepts when relating to these words. These are just two words.

Capability means the ability to do something, for instance, "does company A have the capability to produce product B?" is synonymous with "does company A have the ability to produce product B?" In other words, "CAN company A produce product A?"

In contrast, capacity tells you about the maximum amount/extent something can do, contain, produce, etc., something. For instance, machine A can have a capacity of 2000 parts/min. So the outcome of having this machine producing parts is 2000 parts/min.

I hope this helps.

Hi A,

Capacity is actually a measure of your potential, while capability can be considered its limitation.

Your capability defines your capacity, not vice versa.

Capability: I am even able to do it (knowledge)

Capacity: Do I have bandwith

These two are often used interchangeably.
