Template:Otheruses2 Process (lat. processus - movement) is a naturally occurring or designed sequence of changes of properties/attributes of a system/object.

From the most general systemic perspective it can be continuous or discrete.

Every measurement is a process, therefore it is the foundamental concept in physics, and, in practice, in every science and engineering.

Identification of a process is a subjective task, because whole Universe demostrates one continuous universal process. Every process has the system property, i.e. can be seen as an abstract dynamic system and arbitrarily divided on network of processes. This division depends of the character of changes, theirperception tools and goal of the observer.

Illustration of a process: a geyser in action.

Examples

In engineering perspective, process refers to operations or events, possibly taking up time, space, expertise or other resource, which produces some outcome. A process may be identified by the changes it creates in the properties of one or more objects under its influence. Compare: project.

A process may be categorized as singular, recurrent, or periodic. A singular process would be one which occurs only once. Few processes in nature can be considered singular. Most processes found in nature are recurrent, or repeat more than once. Recurring processes which repeat at a constant rate are considered periodic. The more periodic a process is the more useful it is as the basis of a clock. Below are a few specific examples of processes.
