Only Darrell Mann knows why he left the job of a professor in England to work on toilet improvements in the South East Asia. Anyway, money does not stink. But what is our fault that TRIZ-journal flushes on us his toilet articles now ?
It appears that he forgot (or never knew) the basic management lessons despite published a book titled "Hands on Systematic Innovation for Management". Just in case, I would like to remind him one: When you are deep in the toilet business, keep your mouth shut !
