It is the role of the board to deliver its charter. If it is a for-profit corporation, then its role is to deliver to its shareholders/investors their definition (as interpreted by the board) of value, benefit, growth and risk.

To do that, it must manage its stakeholders to deliver those outcomes. The corporation does not exist for the stakeholders, per se, even though those non-shareholder stakeholders may have a serious interest in the organisation.

If the organisation is a NFP, then the board must ensure that the organisation delivers its charter objectives - no more, no less.

An organisation's Vision should not be its driving force. It's Mission, in definable and quantifiable terms should be its "purpose for existance". The Vision is "merely" the view the organisation has of itself sometime in the future while delivering its mission - and it changes as its context matures.

If you are focussed on the vision, then you seriously risk being captured by the enabler instead of the outcome required.
