I think some people don't truly understand what a Board's function is. It is one of governance and the definition of that [in a business context] is:
Governance means thinking about strategic issues, rather than the operational day-to-day running of the business.
By that definition, all of these fudge ups fall outside the day to day responsibility of the Board. Certainly the Board should be taking steps to make sure their appointed Chief Executive is carrying out their duties properly, they actually have very little visibility of what is happening day in and day out. They are reliant on issues escaping to the outside world or being made aware of issues by their employee [the CE].
If anyone here works in an environment where there is a Board at the top, you will be aware of the constant bitching and moaning about where and when the Board needs to keep their nose out and let the staff do what they are paid to do.
Its not as easy as saying just because the organisation's staff have made mistakes then its the Board's fault.
