If such support and resourcing were not present it would not work.
Chairman Errol Millar said Dr Macpherson's view would be shared by all members.
The board could not pass resolutions and "impose it philosophically" without being committed to what was being tried.
Work on a plan to improve quality at the hospital has been continuing for almost a year behind the scenes, in the hope this would encourage participation by staff.
Hospital advisory committee chairman Richard Thomson told this month's board meeting the worst thing the board could have done would have been to say to clinicians "have we got a great idea for you".
Part of the work on the project, called "putting the patient first", has involved focus groups with staff from a variety of areas considering possible improvements.
This flows on from an earlier pilot project in the emergency department, which was designed to introduce a version of the Toyota vehicle manufacturer's methods to reduce waste, increase efficiency and improve patient flow.
Under the programme, staff were asked to identify where waste occurred and how changes could be made to reduce that.
While the pilot made some gains, its clinical leader Dr Tim Kerruish said last March it would not get much further without a change of culture at the hospital.
Among the issues he raised were the patchy engagement with the project; the existence of a culture of blame where trust was lacking; and the lack of a clear organisational vision or philosophy.
Mr Thomson said a recent workshop to decide what work could be undertaken in the plan had gone much better than he had hoped and the reaction from almost all staff had been "bring it on".
Some staff said things had been tried before and it was important to follow up and learn from those situations.
The draft plan is expected to go to the hospital's clinical board for consideration soon.
If it gains approval, it will go to the hospital advisory committee for discussion and then on to the board.
The plan is based on the Institute of Medicine's six dimensions of quality, which are that care should be safe, patient-centred, efficient, timely, equitable and clinically effective.
