- This guide is primarily designed for practising nurses who wish to develop their units into nursing development units (NDUs). The introduction explains the purpose of the guide and how it is organised. Team Self-Assessment introduces the key qualities and approaches of NDUs and enables teams to identify at what stage they are and which parts of the guide they need to use to start or develop an NDU. Why NDUs? gives a brief account of why NDUs have developed, what they aim to achieve and the methods they use. Developing Your NDU looks at a range of issues which are central to developing and running an NDU. Each subsection of this part is linked with one subsection of the Team Self-Assessment section. Aspects of NDU development covered include team building, team support, marketing, planning, user involvement, equal opportunities and dissemination.
