In 2000, The Allstate Corporation started on an exciting and uncharted new course: to become an early insurance industry adopter of enterprise risk management (ERM). It has been a complex journey that has helped provide a deeper insight into the company’s underlying risk profile, enhanced the way Allstate manages risk in several significant ways and helped generate actions to better exploit risk opportunities.
The company’s initial effort began some years earlier at the direction of then-CFO, Tom Wilson, who established new capital allocation and valuation models for use in the finance function. Later, as Wilson moved into an operating role, John Carl joined Allstate as CFO and asked his staff what the company’s risk-adjusted returns were. A series of conversations resulted in a decision to explore developing a more quantitatively rigorous approach to measuring risk, similar to what was practiced in the oil and gas industry.

>Analysis and Evaluation of Approach
Abstract: In this paper we discuss a case study for the UK Police IT Organisation (PITO) on using a model-based approach to verifying web service composition interactions for a coordinated service-oriented architecture. The move towards implementing web service compositions by multiple interested parties as a form of distributed system architecture promotes the ability to support 1) early verification of service implementations against design specifications and 2) that compositions are built with compatible interfaces for differing scenarios in such a collaborative environment…
Introduction: Our case study is taken from a national development currently underway by the Police IT Organisation (PITO) in the United Kingdom. PITO provides information technology and communication systems to the police service and criminal justice organisations in the UK. PITO’s vision is “to be a trusted and valued partner in the delivery and operation of information and communication solutions to meet the needs of the police service and its partners and stakeholders”. In this way, one of the highest priorities for PITO is its ability to provide secure, reliable, and available services on demand and to provide highly accurate information as a part of the processes carried out to fulfill service requests…
Abstract: A number of techniques and software tools for embedded system design have been recently proposed. However, the current practice in the designer community is heavily based on manual techniques and on past experience rather than on a rigorous approach to design. To advance the state of the art it is important to address a number of relevant design problems and solve them to demonstrate the power of the new approaches.
However, the design methodology followed in practice is far from being at the sophistication level implied by the approaches listed above. The common resistance offered by designers to innovation is made even stronger in the case of embedded system design because of the safety concerns and of the strict constraints on implementation costs.
