According to Ackoff, as presented by Rockwood [1], there are five types of content in the human mind: data, information, knowledge, understanding, and wisdom, in a hierarchical form. Wisdom (as predictability), Understanding (why something happened, putting happening in the frame of a system and finding the acting interconnections), Knowledge (how something happened), Information (what happened) and data (factors involved as well as spatiotemporal conditions of a fact). This is an extension of the DIKW hierarchy (data, information, knowledge, wisdom).Next, Rockwood [2] mentions Peter Drucker's opinion about the difference between doing things right and doing the right thing, with regard to which Dr. Ackoff [3] supports that doing the right thing is wisdom, effectiveness, whereas doing things right is efficiency. He relates the former to effectiveness and wisdom and the latter to efficiency. With which of the five nodes of extended DIKW hierarchy could efficiency be related; probably, with information and surface knowledge, since it lacks the key characteristics of deep knowledge, understanding and wisdom. Next he makes a distinction between doing the right thing wrong and doing the wrong thing right, preferring the former (since it can lead to deeper understanding) to the latter (which perpetuates the false situation). His opinion is revolutionary as he considers that mistakes (either errors of commission or errors of omission) are the key factor of conscience. Ackoff's sayings reveal a higher level human ability, the ability of judging the right against the wrong. This results from a wide experience and the capacity of projection of the past to the …
