Performance in an Organization-- Excerpts from Deming's Out of the Crisis

I. Performance is a function of the system and of special events System

A common fault in the interpretation of events (mistakes, defect, accidents, problems with quality) is to suppose that every event is attributable to someone or is related to special events. The fact is that most troubles with service or production are due to the system.

II. The goal is to develop an stable system then to improve the system

a. Variations on performance are due to common causes (system) and special causes (out side the system). Before we can study a system, we must remove the special causes.

b. A stable process, one with no indication of special variation is said to be in statistical control. In the state of statistical control, all special causes so far detected have been removed. Without statistical control, the process is in unstable chaos, the noise will mask the effect of any attempt to bring improvement to performance. Consequently, before we can improve on performance, we must have the process under control.

III. Differentiating between common and special causes

a. Differentiating between common and special causes is best done with statistics. This is accomplished by studying the frequency distribution of performance. Confidence bands are established to identify outliers. Then we must decide on the reason for the aberrant performance (special cause).

b. Once we have achieved a state of statistical control, control limits tell us what the process is, and what it will do. The control chart is the process talking to us.

c. Without statistical methods, attempts to improve the process are hit or miss, with results that usually make matters worse.

d. The proportion of common and special causes is usually a

split.

IV. Improve quality

V. Basic principles for improving quality

a. Experience alone, without theory, teaches management nothing about what to do to improve quality and competitive position, nor how to do it.

Where do you hope to be five years from now?

How may you reach this goal? By what methods?

b. Top management must be committed to quality and must know what to do to improve it.

c. It is a common supposition that quality and productivity can be achieved by putting on the screws, and by installing gadgets and new machinery. This is the wrong way of doing it.
