 I think what's different about the mega-program approach that we're trying to take now is that it changes the role of CG centres somewhat and adds a layer of responsibility and accountability for working more explicitly with our development and our policy partners to really have impact on the ground and working out how research and being a knowledge partner in doing that and committing to try and make things happen and learn how to do development better Those issues are the ones that make this different make it new, make it exciting and ultimately when it's successful makes it much more gratifying
