Understanding of a stable system discloses devastation of people wrought by the appraisal of performance and futility of management by the numbers, management by MBO.

Deming in the foreword to Walton M 1986 ‘The Deming Management Method’ pxii

The effect (of appraisal) is devastating:
It nourishes short term performance, annihilates long-term planning, builds fear, demolishes teamwork, nourishes rivalry and politics.

It leaves people bitter, crushed, bruised, battered, desolate, despondent, dejected, feeling inferior, some even depressed, unfit for work for weeks after receipt of rating, unable to comprehend why they are inferior. It is unfair, as it ascribes to the people in a group differences that may be caused totally by the system that they work in
