Last year in the USA, a total of US dollars 162 billion was spent on corporate training by various companies. According to Harvard Professor Michael Beer, this is all money sent down the drain. He feels that some of trainings work while many do not. It is not that the content for the training is not up to the mark. Instead it is that the senior management does not do the necessary groundwork before hand. In order for these programmes to succeed, the senior management must be fully aware of what all is needed to fill the gaps. As large organizations are broken down into silos, it is important that they all identify their shortcomings and training programmes commonly address issues but also customize for individual groups.
