Spreadsheets are important business tools. Increasingly they are being used for simulation e.g. to perform risk analysis. Such tasks have far greater computational demands than traditional spreadsheet bookkeeping applications. In this paper we show how spreadsheets can support supercomputing. This is achieved without requiring the spreadsheet user to have specialist tools or knowledge. The key ...

Business process management is often considered as a top-downmanagement activity. This view is inconsistent with the observation that information infrastructures are at drift, outside top-downmanagement control. To reconcile both views, a meta-framework is presented that frames the interplay of the design and emergence of business processes. Business processes are identified as a particular for...

In this paper, a system for capturing and maintaining design rationale is described. The significant contribution of this work is to address the problem of ensuring that the model is followed by the user and to extend the model to include risk analysis. This is accomplished using a software tool (PPIS) that allows the structure of the argumentation process to be made explicit and visible in the...

Shadow Information Technology (IT) occurs when users develop systems outside of the central information technology department. It provides both benefits and risks. Users procuring shadow IT often do not consider integration with existing enterprise architecture, privacy and security protection, maintenance cost, and legal ramifications. Problems with shadow IT must often be resolved by central ...

The study and application of risk analysis provides a set of tools with a strong methodological foundation. This chapter describes how risk analysis can be integrated into the intelligence cycle for producing terrorism threat assessments and warnings. Intelligence professionals can use the risk analyst’s toolbox to sharpen conclusions that are made in intelligence products by providing support ...
