How relevant are Fayol's ideas on managing groups and individuals in today's business world?

Almost 90 years after fayol published his most studied work, Administration Industrielle et Generale, the field of management appears to be undecided on its relevance. The great advances in all aspects of commercial enterprise, which have occurred since 1916, have taught us many things. Just how relevant are fayol's ideas on managing groups and individuals in today's business world? Small parts of fayol's work are certainly not as relevant as they may have been in 1916, and general knowledge now tells us, quite simply, some of the ideas are wrong. However, to discredit the entire work on the basis of several minor sections would be regrettable. The majority of fayol's work on management is still of great relevance to today's business world.
