Popular Prescriptions

The first chapter also makes an interesting point about 'popular prescriptions' and how organizations jump on a 'bandwagon'. This is also true within an organization. I have noticed that if one department starts using a new tool, all the other department start using it too regardless of whether it makes sense or not. Do the people making the decision to use such tools feel that they must adopt other people's ways? Maybe they believe that if they don't, it would somehow reflect badly on them when in reality determining which tools are more appropriate for their department should be the right approach.
