A function is a broad, inherent role or capability of a system or person, focusing on what something is designed to do. A task is a specific, usually finite activity or assignment aimed at achieving a particular goal.

Key Differences
A function represents the main purpose or role of an entity, system, or individual, indicating what it is inherently designed or expected to do. This could be broad, such as the function of a smartphone, which encompasses communication, entertainment, and information retrieval. Whereas, a task refers to a specific, often discrete activity or set of actions aimed at accomplishing a particular objective. For example, using a smartphone to book a flight ticket is a task that utilizes the phone's functions.
Functions are generally stable and define the capabilities of a system or individual. They are broad descriptions of roles that do not change frequently. On the other hand, tasks are dynamic and can vary depending on the objectives at hand. They are specific actions or series of actions taken to utilize the functions of a system or individual for achieving goals.
While functions are more about the potential or capability to perform various activities, tasks are about the actual activities being performed. A function is like the capability of a printer to print, while a task is the action of printing a specific document at a given time.
The identification of functions is crucial in the design and development phase of systems, processes, or roles to ensure they meet the intended purposes. Conversely, tasks are identified during the planning and execution phases to achieve specific objectives using the available functions.
Functions serve as the foundation upon which tasks are formulated. The availability of certain functions determines what tasks can be performed. For instance, the function of an online payment system includes securely processing transactions, which enables the task of purchasing goods online.
