Are PDCA & DAMIC MetaProcesses?The Director of Business Analysis and Process Improvement at a major organization commented: Would you consider PDCA and/or DMAIC to be metaprocesses? My reply: First some background from Wikipedia: PDCA (Plan–Do–Check–Act or Plan–Do–Check–Adjust) is an iterative four-step management method used in business for the control and continuous improvement of processes and products. It is also known as the: Lean manufacturing / Toyota Production System literature. DMAIC (Define, Measure, Analyze, Improve and Control) refers to a data-driven improvement cycle used for improving, optimizing and stabilizing business processes and designs. The DMAIC improvement cycle is the core tool used to drive Six Sigma projects. … All of the DMAIC process steps are required and always proceed in the given order. Here’s how I would answer.
- The first question is whether they are truly processes. The do have steps, but PDCA at least is described as a method. Are methods and processes the same? I’m a little dubious, but for the sake of argument let’s say they are. (Something is only meta- if it is the same kind of thing as the thing it is applied to.)
- The second question is whether they have processes as inputs, and processes as outputs. They do seem to do that.
- The third question is whether they do what all processes do – they (potentially) transform the inputs. They do appear to do that too. (In other words they satisfy the predicate.)
