A Pattern-Based Design Approach for Subscription Management of Software as a Service2009 Congress on Services – I, 2009Co-Authors: Zhongbo Jiang, Kai Tang, Jane L. Snowdon, Xin ZhangAbstract:
Software as a Service (SaaS) is essentially about delivering a software application as a service over the Web with a usage-based charging plan. Existing Web service subscription models do not consider the complexity of the application and the Business environment; for example, multiple service elements with mutual dependencies derived from one application, or various Business Partnership models for reselling and cross-selling services. Therefore the design of subscription management is critical for a SaaS provider to appropriately decompose its application into service elements and then package them into service offerings for a client or Business partner to subscribe according to the nature of the application and the overall Business design. In this paper, we propose a pattern-based approach for the subscription management design of SaaS. A subscription model is introduced first to capture the different entities and their relationships involved in SaaS subscription. Then a method supported with service structure patterns and Business interaction patterns analysis is presented to empower a SaaS provider to design an appropriate subscription model for its service offering. A case study is made to demonstrate the effectiveness of the method at the end of this paper.

Introducing Risk Management into the Grid2006 Second IEEE International Conference on e-Science and Grid Computing (e-Science'06), 2006Co-Authors: Karim Djemame, Iain Gourlay, James Padgett, Georg Birkenheuer, Matthias Hovestadt, Kerstin VossAbstract:
Service Level Agreements (SLAs) are explicit statements about all expectations and obligations in the Business Partnership between customers and providers. They have been introduced in Grid computing to overcome the best effort approach, making the Grid more interesting for commercial applications. However, decisions on negotiation and system management still rely on static approaches, not reflecting the risk linked with decisions. The EC-funded project “AssessGrid” aims at introducing risk assessment and management as a novel decision paradigm into Grid computing. This paper gives a general motivation for risk management and presents the envisaged architecture of a “risk-aware” Grid middleware and Grid fabric, highlighting its functionality by means of three showcase scenarios.

enriching the values of micro and small Business research projects co creation service provision as perceived by academic Business and studentStudies in Higher Education, 2016Co-Authors: James Thatcher, Hanan Alao, Christopher J Brown, Shahriar ChoudharyAbstract:
The National Committee of Inquiry into Higher Education (1996) chaired by Lord Dearing envisioned a university sector central to the UK’s knowledge-based economy. With successive government support the university-Business Partnership ideology has been put into practice. Widening participation has increased in emphasis over recent years, providing key innovations and skills to support Business growth. Yet Business schools activities in Business growth is marginal against other university schools. The paper reports on an empirical study analyzing the university/Business values derived from one small Business engagement project. Data collected through semi-structured interviews, observations, memos, and discussions were coupled with critical evaluation of work and action-based learning (ABL) literature. Analysis reveals evidence of multiple value adding factors; it emerged that the existence of knowledge, present or generated through blended learning techniques, was a key value adding element. The findings e…
