In his blog (David Maister > Passion, People and Principles) David, who earned a lot of money training people, states the (most) training is useless.
He argues that most of the time, companies want changes in behavior from their employees, and send them to a training to accomplish that. But if nothing changes at the company, training won’t help.
David has more inspiring publications on his blog:
– Dangerous Rubbish About Leadership
– Managerial Underperformance
– Marketing is a Conversation
