When a need for dynamic adaptation of an information technology (IT) system arises, often several alternative approaches can be taken. Maximization of technical quality of service (QoS) metrics (e.g., throughput, availability) need not maximize business value metrics (e.g., profit, customer satisfaction). The goal of autonomic business-driven IT system management (BDIM) is to ensure that operation and adaptation of IT systems maximizes business value metrics, with minimal human intervention. The author presents how his WS-Policy4MASC language for specification of management policies for service-oriented systems supports autonomic BDIM. WS-Policy4MASC extends WS-Policy with new types of policy assertions: goal, action, probability, utility, and meta-policy assertions. Its main distinctive characteristics are description of diverse business value metrics and specification of policy conflict resolution strategies for business value maximization according to various business strategies. The author’s decision making algorithms use this additional WS-Policy4MASC information to choose the adaptation approach best from the business viewpoint.

Demand for contemporary IT systems to support chronic availability, expansive integration and extensibility has never been greater. Distributed infrastructures and particularly, the advent of Service Oriented Architecture (SOA) introduce new challenges for meeting these demands. Despite architectural conventions to prescribe a common structure and simplifed approach, these systems are becoming more complex, heterogeneous and critical. Comprehensive System Management is no longer a luxury. Faults and potential failures have to be identified, isolated and addressed, and ideally pre-emptively. Our front-line indicators are alarms

Service Oriented

We examine two open engineering problems in the area of testing and formal verification of internet-enabled service oriented architectures (SOA). The first involves deciding when to formally and exhaustively verify versus when to informally and non-exhaustively test. The second concerns scalability limitations associated with formal verification, to which we propose a semi-formal technique that uses software agents. Finally, we assess how these findings can improve current software quality assurance practices. Addressing the first problem, we present and explain two classes of tradeoffs. External tradeoffs between assurance, performance, and flexibility are determined by the business needs of each application, whether it be in engineering, commerce, or entertainment. Internal tradeoffs between assurance, scale, and level of detail involve the technical challenges of feasibly verifying or testing an SOA. To help decide whether to exhaustively verify or non-exhaustively test, we present and explain these two classes of tradeoffs. Identifying a middle ground between testing and verification, we propose using software agents to simulate services in a composition. Technologically, this approach has the advantage of assuring the quality of compositions that are too large to exhaustively verify. Operationally, it supports testing these compositions in the laboratory without access to source code or use of network resources of third-party services. We identify and exploit the structural similarities between agents and services, examining how doing so can assure the quality of service compositions.

AbstractThe new medical device communication protocol known as IEEE 11073 SDC is well-suited for the integration of (surgical) point-of-care devices, so are the established Health Level Seven (HL7) V2 and Digital Imaging and Communications in Medicine (DICOM) standards for the communication of systems in the clinical IT infrastructure (CITI). An integrated operating room (OR) and other integrated clinical environments, however, need interoperability between both domains to fully unfold their potential for improving the quality of care as well as clinical workflows. This work thus presents concepts for the propagation of clinical and administrative data to medical devices, physiologic measurements and device parameters to clinical IT systems, as well as image and multimedia content in both directions. Prototypical implementations of the derived components have proven to integrate well with systems of networked medical devices and with the CITI, effectively connecting these heterogeneous domains. Our qualitative evaluation indicates that the interoperability concepts are suitable to be integrated into clinical workflows and are expected to benefit patients and clinicians alike. The upcoming HL7 Fast Healthcare Interoperability Resources (FHIR) communication standard will likely change the domain of clinical IT significantly. A straightforward mapping to its resource model thus ensures the tenability of these concepts despite a foreseeable change in demand and requirements.

This paper uses Singapore as a case study to illustrate how staffing policies and practices affect the quality of the workforce which ultimately influence performance at employee and organization level. It reveals that Singapore public service has been able to put in place most of the ‘critical factors’ for an effective staffing system management. The presence of those critical factors have played an important role in making Singapore to be one of the most effective public services in the world. Finally, it forwards theoretical and practical implications of the study and future research direction.

This paper explores the difficulties of building a service-oriented government by taking the evaluation results of public service satisfaction of Guizhou province in 2019 as an example. This paper finds that building a service-oriented government is the process of improving the quality of public service in an all-round way. With the steady improvement of the public service quality in China, the public’s expectation of the public service quality has been improved by changing from the original “yes or no” to the current “good or not”. In order to speed up the construction of service-oriented government, government departments should pay attention to the change of public demand and take the comfort, richness and transparency of public service as the key points of quality improvement.
