Problem solving is improved if you can see it from the view points of I, You, We & Us. This helps to generate ideas to identify and see areas of agreement & disagreement. Another thing to remember is that there has to be an "Owner" of a problem, usually the one who is accountable. otherwise if the solving is left to "Non-owners" it could become a purely hypothetical discussion. You need to have a NEED for resolution, hence the "Owner".
