Table 2.4 summarises the taxonomy proposed by Calkins and Weatherbe. The taxonomy<br />
provides a useful framework but does not consider the wider contextual issues, policies or<br />

Kevany (1995) proposed a more detailed structure to assess the effectiveness of data<br />
sharing. This structure was based on the author’s experience across a range of projects,<br />
particularly at the county, municipality and city levels. Thirty factors that influence data<br />
sharing were identified within nine broad areas: sharing classes, project environment, need<br />
for shared data, opportunity to share data, willingness to share data, incentive to share data,<br />
impediments to share data, technical capability for sharing and resources for sharing.<br />
The factors from the broad areas were rated to provide a measurement framework for<br />
assessing and comparing data sharing arrangements. The assessment was achieved<br />
reasonably efficiently, but involved a degree of judgement and subjectivity (Kevany 1995).<br />
<strong>Data</strong> sharing can also be viewed in terms of antecedents and consequences (Obermeyer &<br />
Pinto 1994; Pinto & Onsrud 1995). The framework proposed by these authors included a<br />
range of events or factors such as incentives, superordinate goals, accessibility, quality of<br />
relationships, bureaucratisation and resource scarcity, which precede the process of data<br />
sharing. The impact of these events and factors then mediated a range of data sharing<br />
consequences such as efficiency, effectiveness and enhanced decision making. Within this<br />
data sharing model the context of the data sharing arrangement was also considered (Pinto<br />
& Onsrud 1995). The context of the exchanges could be project based where organisation<br />
came together to use common data to solve a common problem. Another context was<br />
where different organisations addressed different problems but had a need for similar<br />
information. A third context was where organisations developed generalised patterns of<br />
exchange which led to the development of a centralised data base.
