A process is a series or set of activities that interact to produce a result; it may occur once-only or be recurrent or periodic.

Things called a process include:

Business and management

• Business process, activities that produce a specific service or product for customers
• Business process modeling, activity of representing processes of an enterprise in order to deliver improvements
• Manufacturing process management, a collection of technologies and methods used to define how products are to be manufactured.
• Process architecture, structural design of processes, applies to fields such as computers, business processes, logistics, project management
• Process area, related processes within an area which together satisfies an important goal for improvements within that area
• Process costing, a cost allocation procedure of managerial accounting
• Process management (project management), a systematic series of activities directed towards planning, monitoring the performance and causing an end result in engineering activities, business process, manufacturing processes or project management
• Process-based management, is a management approach that views a business as a collection of processes

Law

• Due process, the concept that governments must respect the rule of law
• Legal process, the proceedings and records of a legal case
• Service of process, the procedure of giving official notice of a legal proceeding

Science and technology

• The general concept of the scientific process, see scientific method
• Process theory, the scientific study of processes
• Industrial processes, consists of the purposeful sequencing of tasks that combine resources to produce a desired output

Biology and psychology

• Process (anatomy), a projection or outgrowth of tissue from a larger body
• Biological process, a process of a living organism
• Cognitive process, such as attention, memory, language use, reasoning, and problem solving
• Mental process, a function or processes of the mind
• Neuronal process, also neurite, a projection from the cell body of a neuron

Chemistry

• Chemical process, a method or means of changing one or more chemicals or chemical compounds
• Unit process, a step in manufacturing in which chemical reaction takes place

Computing

• Process (computing), a computer program, or running a program concurrently with other programs
  • Child process, created by another process
  • Parent process
• Process management (computing), an integral part of any modern-day operating system (OS)
• Processing (programming language), an open-source language and integrated development environment

Mathematics

• In probability theory:
  • Branching process, a Markov process that models a population
  • Diffusion process, a solution to a stochastic differential equation
  • Empirical process, a stochastic process that describes the proportion of objects in a system in a given state
  • Lévy process, a stochastic process with independent, stationary increments
  • Poisson process, a point process consisting of randomly located points on some underlying space
  • Predictable process, a stochastic process whose value is knowable
  • Stochastic process, a random process, as opposed to a deterministic process
  • Wiener process, a continuous-time stochastic process
• Process calculus, a diverse family of related approaches for formally modeling concurrent systems
• Process function, a mathematical concept used in thermodynamics

Thermodynamics

• Process function, a mathematical concept used in thermodynamics
• Thermodynamic process, the energetic evolution of a thermodynamic system
  • Adiabatic process, which proceeds without transfer of heat or matter between a system and its surroundings
  • Isenthalpic process, in which enthalpy stays constant
  • Isobaric process, in which the pressure stays constant
  • Isochoric process, in which volume stays constant
  • Isothermal process, in which temperature stays constant
  • Polytropic process, which obeys the equation ${\displaystyle pv^{\,n}=C}$
