Process merely means work. All of us work (with brawn, brains, machines or a combination) to add value to inputs. These inputs are information, materials or subassemblies. One could also argue that training and educating are processes that have people as input to whom value should be added. We agree.
The value of the output must exceed the cost of inputs, resources and controls to stay in business. The resources are facilities, equipment, skills and knowledge. The controls are methods, procedures (or instructions), care and attitude.
