Managing risk is a necessary component of project management. Unfortunately it is often neglected right up until the point where there is a serious problem that needs to be adressed. Ignoring risks until they materialize is guaranteed to blow your budget and schedule every time - and it will add a lot of unnecessary stress to boot.
