Promise theory
Promise Theory is a method of analysis suitable for studying any system of interacting components. In the context of information science, Promise Theory offers a methodology for organising and understanding systems by modelling voluntary cooperation between individual actors or agents, which make public their 'intentions' to one another in the form of promises. Promise Theory is grounded in graph theory and set theory.
The goal of Promise Theory is to reveal the behavior of a whole by taking the viewpoint of the parts rather than the whole. In other words, it is a bottom-up, constructionist view of the world. Promise Theory is not a technology or design methodology. It doesn't advocate any position or design principle, except as a method of analysis.
Promise Theory is being used in a variety of disciplines ranging from network (SDN) and computer systems management to organizations and finance.
