Inputs, which are the 'raw material' that gets transformed during the activity, e.g. a wire coil, outline plans.
• Controls, which influence or direct how the process works, e.g. safety standards, customer requirements, project plans.
• Mechanisms, which cause the process to operate, e.g. people, tools, machines.
• Outputs, which are the result of the activity and are transmitted to other processes, e.g. cut lengths of wire, final plans.
