“Measurement is the first step that leads to control.If you can’t measure something, you can’t understand it. If you can’t understand it, you can’t control it. If you can’t control it, you can’t improve it.” H. James Harrington

General Rule of Thumb:

Statement Analysis cont’

#1 When seeking the truth, never rely on any single point as a decider. Always look for clusters of behaviors as indicators only.

#2 Look for about 33% division in a statement; beginning, middle, end.

#3 Identify pronoun and tense consistency; changes in terms indicate changes in reality.

#4 If the subject didn’t say it, then it didn’t happen – don’t fill in the blanks for them.

Whether written or spoken, the truth will reveal itself to the attentive listener.

In the field of observation, chance favors the prepared mind. Dr. Louis Pasteur
