SHELF: The sheffield elicitation framework

Abstract

The Sheffield elicitation framework is an expert knowledge elicitation framework that has been devised over a number of years and many substantial expert knowledge elicitation exercises to give a transparent and reliable way of collecting expert opinions. The framework is based on the principles of behavioural aggregation where a facilitator-guided group interact and share information to arrive at a consensus. It was originally designed for helping to elicit judgements about single uncertain variables, but, in recent years, the framework and the associated software implementations have been extended to accommodate judgements about more complex multidimensional variables and geographically-dispersed experts. In this chapter, we discuss the aims and foundations of the framework, its extensions and its notable applications.
