ISO systems are more low key and are made up of a lot of behind the scenes work. The outputs are not flashy and since it deals mostly with quality and to be honest typically quality problems they choose not to focus on it. Also, ISO tends to be a lot of paperwork and meetings because companies set the system to look pretty for customers and auditors. This often means that the system is setup to reflect some dreamy future state as opposed to setup like we really run the business on a day-to-day basis, which of course the system is not used as it should be and everyone rushes around before the audits to update things.
I'm sorry that this has been your experience - it's a problem with the understanding of what the Standard actually says and requires, and thus poor implementation. As you say:
most of the executives that I have dealt with did not really understand what ISO was and what it could do for the organization if used effectively.
Exactly. If they did, they wouln't tolerate such silly systems of 'paperwork and meetings' for a moment.
A real, dynamic and well implemented quality management system a la 9001 becomes 'what we do everyday to manage and improve our business' - what's boring about increasing customer satisfaction? continuously improving? improving processes and services/products?. Such a system is a different thing altogether, and will happily embrace, work with and make excellent use of such tools as Lean and 6 Sigma, as Harang and others say.
A system is, by its very nature, something that is more than the sum of its parts.
