E-CARGO (Environments - Classes, Agents, Roles, Groups, and Objects) is a model for investigating complex systems. It provides a high-level framework for collaboration, a composition structure for a complex system, and makes a collaboration system analyzable and designable. E-CARGO model defines a system by identifying the environments, classes, agents, roles, groups, and objects that interact within it. It also describes the interactions between these components and how they affect the overall system. E-CARGO is used in interdisciplinary research to clarify the nature of collaboration and how roles play a crucial part in it. It can be used to model, formalize, analyze, and solve complex problems that were previously only solvable through informal means.
