I think it is not so much the sheer size of the organization as the scope of operations. I can easily envision a thousand employee assembly operation (one product, all components outsourced and brought to one location for final assembly) getting along with some non-professional (no certifications, no specific training in SPC, etc.) executive ALSO having some of the duties of a quality manager while farming out supplier quality oversight to a third party group or team. Easier still to envision a supermarket chain or insurance company with hundreds or thousands of employees with no trained professional as the guy overseeing quality, most likely without "quality" anywhere in his job title.
I find it less credible that a hard-core manufacturing facility would not have a full or part-time quality professional (with or without "quality" anywhere in his job title) to oversee operations with an on-going program of continual improvement, regardless whether the facility had ISO or other registration or whether they ever used the specific term "continual improvement" because it just makes good business sense. In fact I have seen several small to medium sized operations (up to 300 employees) where the "quality manager" function was a subset of the "plant manager" job title and the person did have formal training in various quality engineer tools.

. It might be too difficult for any organization to succesfully implement perhaps, due to a lack of uber-quality-culture, but I do believe it's pros are stronger than it cons.
