The third unit is about staff development. The concept of staff development recognises that all people may improve their capabilities and become more efficient at what they are doing. Much of the time we are likely to say ‘This is an area in which I think I can do better’. We may be aware that we can improve by observing the performance of others. Sometimes, however, we need another trusted person to help us identify those areas in which we need to better our performance. Once we have done this, there are various ways in which we can get others to assist us in the process of self-development.
