Initial ideas are presented concerning the application of risk to IT service management. Focus is on the process of testing changes to a service where risk considerations are paramount. In particular, the decision problem of which tests to perform after a change is discussed. Several approaches to formalizing this decision problem are presented with particular reference to the numerical representation of risk metrics and of risk appetite. The paper offers no final results but a rich set of alternatives for discussion by the research community.

The timely and efficient management of faults that affect the quality of services delivered to customers is an important issue for service providers with respect to their business goals. It includes the diagnosis of service faults which deals with the localization of their root causes within subservices and resources being part of the service realization. In this paper our service-oriented event correlation approach, which uses event correlation techniques to automate the diagnosis on the service layer is detailed. Our algorithm for the hybrid rule-based/case-based correlation methodology that also includes recently proposed active probing techniques is presented as well as its prototypical implementation at the Leibniz Supercomputing Center. This implementation is not limited to a small test environment, but has been carried out for requirements of the environment of this large service provider.

This paper presents the case for the introduction of flexibility into MMF-based software project management. It shows that, in cases of high volatility, the optimum financial return is obtained when the manager follows a flexible plan (policy) instead of a rigid one.

The management of IT-infrastructures has gained increased relevance to business as business processes and thus the business profit rely on IT services, which in turn depend on the underlying infrastructure. Even one single distributed IT service already depends on the correct interaction of many distributed IT resources within the IT infrastructure. The term service infrastructure in this context denotes the IT infrastructure resources which are involved within a service and are thereby in a relationship among each other. The changing states of resources and resource dependencies manifest the behaviour of the infrastructure and is correlated with the behaviour of a service facing the user and thus with the service quality. Thereby resource dependencies are of interest in the context of BDIM.

In this paper, we will discuss the business model design for the deployment of capacity-driven services from high altitude platforms (HAPs). Key factors of successfully delivering the HAP services will be investigated in terms of coexisting with current major wireless broadband and cellular network operators in a long term perspective. A partnership-based business model will be proposed and demonstrated to be effective. We will mainly concentrate on describing how HAP wireless network operator could establish its network and cooperate with other actors being in the proposed business model.

In this paper we consider a peer-to-peer grid system which provides multiple services to its users. In this system, an incentive mechanism promotes collaboration among peers. It has been shown that the use of a reciprocation mechanism in such a system is able to prevent free riding and, at the same time, promotes the clustering of peers that have mutually profitable interactions. However, when peers are subject to a budget limitation, each peer must select a subset of all services that can possibly be offered. In this work we show that the received utility is strongly dependent of the offered services. The main contributions of this work are a methodology to evaluate the impact of service changes in the obtained utility and how much different sets of offered services impact in the peer's utility. These results indicate that further research is needed, particularly for the development of heuristics to choose the best services to offer.

This work presents a method that provides organizations and their project managers with a better understanding of the implications of the risks that software projects are subjected to. The method, which is based upon a novel approach to cluster analysis, generates a set of business rules indicating how risk factors may influence project performance. These rules are easy to read and understand, making it easier for managers to identify what needs to be done and when it needs to be done, before the worst happens.

Off shoring IT services has become a key factor in building successful business strategies, allowing companies to better position themselves in today's highly competitive markets. Nevertheless, off shoring brings to the table a brand new set of possibilities and risks regarding its management and execution. This article presents a method for the elaboration of a quantitative risk model for off shoring IT applications, which, in turn, increases the likelihood of being successful in such initiatives.

This paper defines an approach to maintain the work of business process analysis aligned with the work of UI designers. With this approach, models are derived from each other and aligned in order to more efficiently propagate changes when needed. In this way, each model modification could be adequately propagated in the rest of the chain. By applying this model-driven approach, the user interfaces of the information systems are abstracted from models and their interrelationships, thus directly meeting the requirements of the business processes. This approach has been validated on a case study in a large bank-insurance organization and with the implementation of a traceability tool.
