Are PDCA & DAMIC MetaProcesses?

The Director of Business Analysis and Process Improvement at a major organization commented[1]: 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:
    • Deming circle/cycle/wheel.
    • Shewhart cycle.
    • control circle/cycle, or plan–do–study–act (PDSA).
Another version of this PDCA cycle is OPDCA. The added “O” stands for observation or as some versions say “Grasp the current condition.” This emphasis on observation and current condition has currency with 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.)
So I would give a tentative yes to whether they are metaprocesses. http://www.brsolutions.com/

[1] This series of point/counterpoint replies is a follow-up to my post “Meta Here. Meta There. Meta Everywhere?” (March 31, 2014), which generated a surprising amount of great discussion. (Thanks all!) Refer to: http://www.brsolutions.com/2014/03/31/meta-here-meta-there-meta-everywhere/ The definition I’m using for meta- is from Merriam-Webster’s Unabridged Dictionary [3b]:

3b: of a higher logical type – in nouns formed from names of disciplines and designating new but related disciplines such as can deal critically with the nature, structure, or behavior of the original ones *metalanguage* *metatheory* *metasystem*
