What is the difference between a system and a process?

Processes

  • A process produces results through work being done in the process.

  • Processes produce outputs

  • Process owners manage process outputs

Systems

  • A system produces results through the interaction of processes
  • Systems create outcomes
  • System managers (CEO) manage outcomes

There are therefore two quite different types of management.

  • There is process management which will manage the achievement of results by planning, organizing, controlling and continually improving the work required to produce them.

  • There is system management which will manage a system of interacting processes that function together to achieve certain goals.

The boundary between process and system is where the output fulfils a system objective. E.g If we treat the series of steps in frying an egg as a process, we will find that frying the egg is one stage of a meal preparation process. The meal preparation process is one stage in the service delivery process. Any of these processes can interact with the outputs from a process that manages the resources used in meal preparation process. Cut off the supply of electricity and the cook can’t fry the egg. We therefore ascend through a hierarchy of processes to a system of processes which function together (interact) to deliver an experience that will delight the customer – the objective of frying the egg, preparing the meal and delivering the service.
