Management process

Considering a job of all managers all around the world as one huge process, pick three groups of words: one group for its inputs, another group for its tools and techniques, and the third group for the output of this process. If the task were about scrambled egg cooking, for instance, raw eggs, frying oil, and gas could be some of inputs; recipe, stove, and frying pan would be main tools and techniques, and scrambled eggs would be the major output.
