What are the reasons for experts saying that you are entering a 'new' era of management?
New era of management means that the modern generation of managers are practising new management techniques. This techniques have been evolved/invented while practising the old management.When old management style did not work on a particular thing, it was the new trick/idea which worked (Because a problem has to be closed). So now a days modern managers beilve and practise new management techniques.As there are old school of thoughts about the management, there are new also.To my understanding there should be a mixture of both thoughts.As the experince and invention would get along we will find more new management  techniques. Pradeep ShuklaHyderabad, India
