**Object Process Methodology** (OPM) is a conceptual modeling language and methodology for capturing knowledge and designing systems. Based on a minimal universal ontology of stateful objects and processes that transform them.

OPM can be used to formally specify the function, structure, and behavior of artificial and natural systems in a large variety of domains.
An OPM **model** is a conceptual model that uses objects, processes, and relations among them, to represent the structure, behavior, and function of a system at various levels of detail in a unified model expressed in both graphics and text.
The **structure** of a system is its form--the assembly of its physical and informatical components, along with the long-lasting relations among them.
The **behavior** of a system is its dynamics--the way the system changes over time by transforming objects.
Main **function** of a system is the combination of the main object and main process of the system. In a human-made system, the function is what provides the benefit to the system's beneficiary.
