Ever since organizations have existed attempts have been made to develop and change them. Certainly over the past hundred or so years this process has become more intense, and today it could be seen as an ongoing requirement for any organization that wishes to survive and succeed. Enough has been said and written about the whole subject for us to accept that the attitudes and behaviour of the people in the organization are very important to the long-term effectiveness of any process of change, development and improvement. In the early part of this century Frederick Taylor developed his famous theory of 'scientific management'. Many of the entrepreneurs who were in business at the time took serious exception to his views on the basis that he was questioning their superior ability, intellect and judgement, and that since they had been so successful for so long, there was nothing significant that he could teach them.
