If you go down one level, certainly the degree of parliamentary control increases.
I believe I mentioned earlier that if you look at strategic outcome, you're looking at roughly 290 strategic outcomes, and if you go one level down, you're at about 550. You're quite right that from a parliamentary control perspective it puts greater control at that level.
From a departmental perspective, that would cause a fundamental shift in how they actually do their planning and spending. When departments got back to us about what the cost to implement such a structure might be, they said the cost would go up by about half.
There were some concerns about what it would do from a management perspective. To actually control at that next level down would cause them some issues. That's not to say it's not the right thing to do, but understand there is a significant impact on departmental operations the greater the degree of control by Parliament.
That's the trade-off. Departments right now plan at a very high level where their controls are. The further down you go, the more process you add at the departmental level.
