Experience in the use of research planning diagrams in a synthetic fibres R & D unit

. This paper describes the introduction and use of the Research Planning Diagram (RPD) notation in ICI Fibres Limited. Experimenting with the approach has led to the conclusion that it is very useful for planning and controlling development projects but we do not think it serves a real purpose when applied to basic research with a high level of technical content. Support is provided for the view that the RPD notation should be used to give prominence to decisions and that it can be employed as a communications link between different functions in a business area responsible for the successful completion of a project. The paper explains how the RPD notation is used on a routine basis in the management of development projects and describes the benefits that have been derived from its implementation. An illustration is included to show how the notation has been modified to permit criteria and data, relevant to the analysis of key decisions, to be added to the diagram.
