By thinking about daily activities as processes, we gain insights for making improvements. All processes have inputs, all processes have steps, and all processes have outcomes. For each step, one could also identify where work is backing up or the reasons for rework or problems. Ideas for improvement could be developed and tested from this information.
For an individual or organization just beginning to develop the skills of improvement, creating standard processes to replace chaotic and wasteful activity is an important source of improvement. As people advance in their skills at making improvements, they realize that further improvements can be made by putting processes in the context of the system in which the processes are embedded.
A system is an interdependent group of items, people, or processes with a common purpose. Driving to work is a process. Getting a family out of bed, fed, dressed, and transported to work and school is a system. Orienting a new employee is a process; creating satisfied, productive employees takes a system. In a system, not only the parts but the relationships among the parts become opportunities for improvement.
The process of obtaining a blood analysis is part of the bigger system of delivering health care for a patient in a hospital. The process for obtaining the blood analysis may be flawless, but care will be affected by the timely and effective action taken for the patient on the basis of the analysis.
In a system, everything affects everything else. One area could make a change that results in improvement for some people but harm the overall system. From the customer's viewpoint, things could be worse. For example, the purchasing department may change suppliers of a raw material to reduce costs, which results in a lower-quality product and more returns from customers. When fundamental changes are developed, the interdependencies within the system must be considered.
