The utilisation of laboratory services for patient diagnosis and management involves many steps with both clinical and laboratory components. The clinical components include the decision to order a test, interpretation of the test results and actions taken on the basis of the results. The laboratory components on the other hand include receipt of the(More)
We studied the potential benefit of using artificial neural networks (ANNs) for the diagnosis of thyroid function. We examined two types of ANN architecture and assessed their robustness in the face of diagnostic noise. The thyroid function data we used had previously been studied by multivariate statistical methods and a variety of pattern-recognition(More)
Service Level Agreements (SLAs) are the de facto method of managing IT Outsourcing (ITO) contracts. Negotiated during pursuit (pre-sales) phase and then used as a dashboard for performance management during delivery the SLA ultimately becomes both the lever and the measurable for revenue and margin performance on a contract.

We suggest that an essential component of an analysis of this problem must be an account of the structure of the system/network and the services it is intended to deliver. We apply the methods of classical applied mathematics-using tools drawn from algebra,(More)
In this paper we seek to understand how individuals, as part of a group facilitated modelling setting, commit themselves to a set of actions, as a basis of sense-making, sense-giving and coordinated actions. For this we introduce Pickering's Mangle of Practice to understand the practice of a group facilitated modelling setting. Using video data from a group(More)
