Process

Process (lat. processus - movement) is a naturally occurring or designed sequence of changes of properties or attributes of an object or system. More precisely, and from the most general systemic perspective, every process is representable as a particular trajectory (or part thereof) in a system's phase space.

Every measurement is a process. The process of measurement is the fundamental concept in physics, and, in practice, in every field of science and engineering.

For the above goal-oriented reason, from the industrial managerial point of view, the following inputs can be initially applied in an engineering process specification: people, machines and tools, materials, energy, information, professional knowledge, capital, time and space .

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. Various specific processes:
