I think one of the issues that Ian pointed to is the mandating, having a mandate that very clearly sets out from the beginning what the political objective is and not having 290 other tasks that also need to be done at the same time.
Also, there's some work that can be done in mandating a new mission or a mission that's in transition, in working with the parties to the conflict so that they have a better understanding of what the deployment is about from the outset and have expressed consent to it, rather than imposing mandates from the outside.
The HIPPO report proposed a two-step mandating process that would have done consultations ahead of mandating.
