Well, I'd say that Ken makes an interesting point. He says that in the UK accountants only need to be professionally accredited if they intend to work in auditing or insolvency: http://kenschwaber.wordpress.com/20...rofession/
Personally I'd go a step further. I'd observe that there is a strong correlation between professionalism in our industry and the management of technical debt, for which transparency and metrics are key. On the other hand, a lack of professionalism can be expected to result in opaque levels of technical debt that resist auditing.
My conclusion: Professionalism in our field, in so far as it can be said to exist at all, is *also* largely about the avoidance of insolvency and the transparent and sustainable management of debt.
