The speed of decision making is a critical factor for successful project delivery in the fast-paced environment of delivering a major infrastructure project. Therefore, the governance structure should include clearly delegated authority levels to ensure that decisions under the PAA (in particular, decisions which rely upon the Owner's Reserved Powers) be made in the most timely and efficient manner for the project.
Any delegated authority levels should be subject to governance controls over expenditure for project decisions outside the scope of the alliance.
