A Steering manager uses the Law of Diminishing Response as a guide to successful control interventions. When you consider adding some pressure, the key variable to monitor is not people’s performance, but their responsiveness. How are they responding to the existing pressures? When they hear of a new “challenge,” do they drop their head a quarter of an inch and mumble an acceptance under their breath? Do they become annoyed and give a hundred reasons why it can’t be done? Do they show external signs of panic? These are all signs that they’ve reached the point where responsiveness has gone negative, yet they are unable to control their own response.

On the other hand, are people alert and genuinely enthusiastic, able to ask penetrating questions that need answering before accepting the extra work? Can they consciously trade off less important work for high-priority assignments? These are signs that their responsiveness is still above zero, so it’s okay to pile a little more fuel on the fire; but don’t make any assumptions about next time.
