Key findings relating to the operational phase: 

•  performance against benchmarks to date is mixed, and it will take time and good information to determine whether performance will improve;

•  the deal is clearly specified and understood in general and the parties are building a good relationship, but it is unclear whether the oversight mechanisms in the contracts will be sufficient;

•  an independent arbiter can review the contract every seven years and as a result, price and scope can change;

•  availability performance was very volatile during the period of shadow running;

•  performance was uneven in the first year;

•  parties have entered into the spirit of partnership, and monitor and review the partnership regularly; and

•  it is too early to determine if parties will promote innovation and a whole business approach.
