Proposal of nursing transformation.

The CEO of our organization (national guard health affairs) asked to do a proposal of nursing transformation.
He wants to move from traditional nursing model in Saudi Arabia (centralized one) to shared governance one as it is the best practice …
He wants to have unit-based council.!!!
Why we must move from traditional nursing to shared governance in our hospital ?
What will we achieve?
How can we achieve? Implement? Measure progress?
And if we successful achieve our goal …what next ?
