“Prove It,” Regulators Say Walter Deming, the legendary physicist and management consultant, once described research this way: “Uncertainty makes research predictable, but you still need proof to satisfy everyone else1.” In one sentence, Deming perfectly describes why compliance management in government regulated industries is now so dependent upon metrology, or the science of measurement. When it comes to manufacturing products that can affect public health, scientists need to prove the integrity of their data or risk having their laboratories cited - or even shut down.
