I can use the RCAF as an example. Starting last year, we were told to get on board with activity based planning for our funding. This year, we took it a step further and were told to start at zero, and business plan based on the expected expenditures for the activities, rather than up to a notional allocation. Then at the L1, they can determine which activities will occur and receive full funding and which won't. I firmly believe this is a better way to do things, because then you don't half ass a lot of things that may or may not be important to your mandate.
On the project side, word came down recently that we are already bumping up against the 3.5% number CAF wide for the out years, and may need to start thinking about taking an appetite suppressant on some of the projects. Does this mean we shelve certain plans? Do we descope things? What we can no longer afford to do is commit PYs to projects and activities that have little chance of coming to fruition in the near future due to funding limitations, because we have so many projects/activities going forward that don't have adequate PYs assigned already.
