- Heterarchy: An ordering of things in which there is no single peak or leading element, and which element is dominant at a given time depends on the total situation, often used in contrast to hierarchy, also a vertical arrangement of entities (systems and their subsystems), usually ordered from the top downwards rather than from the bottom upwards.
- Holarchy: A concept invented by Arthur Köestler to describe behavior that is partly a function of individual nature and partly a function of the nature of the embedding system, generally operating in a bottom upwards fashion.
- Holism: A non-reductionist descriptive and investigative strategy for generating explanatory principles of whole systems. Attention is focused on the emergent properties of the whole rather than on the reductionist behavior of the isolated parts. The approach typically involves and generates empathetic, experiential, and intuitive understanding, not merely analytic understanding, since by the definition of the approach, these forms are not truly separable (as nothing is).
- Holon (philosophy): A whole in itself as well as a part of a larger system.
- Homeorhesis is a concept encompassing dynamical systems which return to a trajectory, as opposed to systems which return to a particular state, which is termed homeostasis.
- Homeostasis is that property of either an open system or a closed system, especially a living organism, which regulates its internal environment so as to maintain a stable, constant condition.
- Human Activity Systems: Designed social systems organized for a purpose, which they attain by carrying out specific functions.
