“The one thing an [OKR] system should provide par excellence is focus. This can only happen if we keep the number of objectives small …. Each time you make a commitment, you forfeit your chance to commit to something else. This, of course, is an inevitable, inescapable consequence of allocating any finite resource. People who plan have to have the guts, honesty, and discipline to drop projects as well as to initiate them, to shake their heads “no” as well as to smile “yes.” … We must realize—and act on the realization—that if we try to focus on everything, we focus on nothing.”
