Also affecting an individual’s movement up the ladder over time is the mental capability of each individual. Over time mental capability increases and shows up in the higher rungs of the ladder as shown in the “Technical Thought Processing Capabilities” figures. The mental capability was described in Chapter 9 and is based upon the principles of Executive Leadership written by Elliott Jaques.
With respect to the seven levels of a technical ladder for typical chemical companies, the thought processing capability and technical skill level definitions are extremely important. They are needed to understand and accurately place individuals on this “Technical Thought Processing Capabilities” matrix so that human resource planning as described in Chapter 9 and strategic business and technology planning as described in Chapters 6 and 7 can be productively accomplished.
