Key Differences

Capability represents the potential or inherent abilities of a person, organization, or object. It implies the capacity to achieve a certain outcome or perform various tasks. When discussing a person's capabilities, it often relates to their skills, knowledge, or talent. In the context of technology or machinery, capability refers to what the system or device is potentially able to do, given the right conditions.
Functionality, on the other hand, focuses more on the practical uses or operations that something can perform. It is about the range of functions or features that a device, system, or software offers. Functionality is often assessed in terms of how effectively these functions are executed and how they serve the intended purpose or solve specific problems.
In terms of application, capability often precedes functionality. For instance, a smartphone has the capability to access the internet based on its design and built-in technology. However, the functionality of the smartphone includes specific features like browsing web pages, downloading apps, or streaming videos. Functionality is the realization or execution of the capabilities.
While capability is more about potential, functionality is about practical execution. A company might have the capability to expand internationally due to its resources and market position, but the actual functionality of this expansion involves the practical steps, strategies, and operations necessary to make it successful in a global market.
