Hi Roger
Jim answered your points pretty comprehensively but I would like to add my two penneth for what it's worth.
I note that you say that you have worked for the same company for 18 years and in the last 10 years you have seen five quality managers come and go. This seems high and although you concentrate on the quality managers I wager that your company has a high turnover of staff in all areas of the business, with the possible exception of Senior Management. My question is how come you are still there? I mean the odds don't stack up!
I don't know the individual circumstances in your case but there are many reasons why a quality manger would leave a post - not least of which is lack of support from senior management, a quality managers position probably more than anybody's in an organisation requires it and is doomed to eventual failure without it - unless of course you are happy just to collect your pay cheque.
Even a good, experienced, busy, knowledgeable and personable quality manager needs at least 12-18 months in a post before they can start to have a positive impact on the business and this lack of continuity must have had a negative impact on your business.
At the end of the day though most organisations are measured by financial results and your organisation is I presume still in business. It's the ten years of unquantifiable, missed opportunities that frustrate so damn much.
Let's hope all five of them have gone on to bigger and better things!
Regards,
Simon
