Workflow is an implementation of process. Process is a template defining structure, rules, objects and their relations in a business environment associated with certain business goal or case. Workflow is a concrete realization of process in given business context. In other words, process is a plan, while workflow is a sequence of business actions taken according to this plan. Process is an architectural project, while workflow is a building created on this architecture. Multiple buildings can be erected from the same architecture. Unlimited sequences of actions can run along the same plan. But the plan or architecture behind all these varieties of buildings and sequences is a common ground cementing their distinguished similarity as a family.
