Jungleboy - that is not how things operate in the private sector, for obvious reasons. You won't find cross-sector management pollution like you do in the public sector at all. The CEO of Pick N Pay is most certainly not in a position to lead AngloGold to success. At most they will cross industries within the same sector, but jumping sectors in a senior management position requires significant experience and expertise in that sector.
A perfect example here is Mr Balfour who jumped from sports minister to correctional services minister and that is a problem. This is commonplace in the public sector however common sense says that there is very little in his education or experience that makes him qualified for the position. In fact his experience wasn't right to manage the sports portfolio either. However there is no operational synergy between sports and correctional services. You're harping on under the false illusion that a CEO is responsible for only the financial health of a company which is patently false. They are ultimately responsible for general operations, overall financial health, risk management, regulatory and legal issues, marketing, sales and distribution, personnel, corporate finance, general administration, investor relations, planning and management of all of these things as well. All of which require a significant understanding of the sector, industry and the company itself. If cross-sector pollution happened in the private sector like it does in the public sector, investor confidence would drop completely - ask any investor about this. This is why it is best practice for companies to advertise their senior management's experience and expertise on their investor relations website.
It therefore stands to reason that if we resolved these management issues in government, investor sentiment for SA would increase significantly. What you're highlighting is essentially a board member's responsibilities who are only interested in value derived for shareholders - financial reasons only pretty much. That is government (as a shareholder) in this scenario. The man on the ground ultimately responsible (the CEO or minister in this case) MUST have extensive expertise, experience and education in the sector and industry. The board members hire the CEO/minister...
