In the science of quantum physics, Werner Heisenberg postulated that the more precisely we can measure the location of a particle, the less precisely we can measure its momentum--and vice versa. This principle, first formulated in 1927 is known as "Heisenberg's Uncertainty Principle."
Within management sciences, it seems to have a variant: "The more precisely we try to report on what we've done, the less effective we are at productively satisfying our mandate." Managers love reports. They want to know everything about anything as if reports, pie charts, and trend lines will make them feel more in control of a large department where they can't possibly expect to follow every detail as it transpires--but wish they could.
