It is not just the end of science, it also requires the end of human
creativity being applied to business problems. (01)
In an earlier stage of life, I sold maintenance management systems. It
quickly became clear that the functions required of the system had less
to do with the industry that the company was in than the management
style of the companies' leaders.
The way a petrochemical plant thought about their processes, maintenance
needs and equipment hierarchy might be much more similar to a pulp and
paper mill than the chemical plant across the street. (02)
