　　The American s reputation was created in the I 980s by the spectacular success of one book, In Search of Excellence, co-written with Robert Waterman.

　　Although his ideas have been criticised, Peters popularity as a speaker and writer has continued to grow. So much so that Peters has created his own business to market books, videos and consultancy based on his work.
