The Board's vulnerability to management capture
A lack of clarity about the Governors' chief responsibilities - regulators or defenders of management?
A lack of transparency, particularly in complaints
Poor public accountability
The strategy we set out in Building Public Value is radical in addressing these four weaknesses.
Management capture
Up to now the Governors have only had access to a very limited resource to provide independent advice and analysis of management proposals.
That's changed.
We're now building a Governance Unit staffed by experts in a range of fields, from performance monitoring, to broadcast strategy and economics and with access to a wide range of external advisers
It's already having an impact
This week saw the culmination of three months work in which the Governors have scrutinised the four major reviews currently underway which will have radical implications for the BBC and therefore licence-fee payers.
We have taken expert, external advice
We have challenged management on their thinking and their assumptions
We support management's strategy to deliver the vision of Building Public Value which Mark Thompson will be speaking about next week
And we have now asked them to bring to us more detailed plans, which will be subject to external, independent validation and audit before the Governors sign-off the Director General's proposals
Our only concern in this process has been to ensure that whatever the outcome of the reviews, the licence fee payer receives a better service.
This ability to be separate from management and yet also engaged is what marks out the BBC's unique system of governance.
It is worth preserving for one simple reason - it is the only way that we can establish a direct link between the interests of the public and the actions of the management.
Clarifying the Governors' role
Many people say the Governors are inevitably torn between their duties as regulators and their duty as Governors to defend BBC management.
I've never seen it as the job of Governors to defend BBC management - rather, it's their job to defend the BBC for the licence fee payer.
But it really is a false dichotomy to see the Governors' job as regulator as incompatible with that of governance.
In commercial companies there is an inevitable tension between regulation - which is in the public interest - and governance, which is in the interest of shareholders.
In the case of the BBC the public are our shareholders and for that reason regulation and governance work best when they work together - that's exactly what we've been doing this week, ensuring the objectives we agree with management are effectively and efficiently delivered by them. This is what makes the BBC different.
The reforms we are putting in place are therefore focused on establishing clear distance between the governors as custodians of the public interest and the management.
To that end:
We're introducing Service Licences next year, setting out clear, objective criteria by which we - and the public - will be able to judge their performance
We'll carry out a regular cycle of reviews of services which we'll publish
We'll apply the Public Value Test to any new service or major change to any existing service to make sure it really is in the public interest
We can say more about the detail of these reforms later
That's a start but we need to go further. We're now drafting the idea of a Governors' Protocol:
This would set out the different ways in which the Board would be required to act independently of management
