This paper uses data from a program of customer interviews and focus group research conducted by the Australian government to develop an electronic services evaluation and design framework. A proven theory building approach has been used to develop and confirm the various components of electronic government (e-government) use and satisfaction from original government studies conducted in Australia and to create the new evaluation framework. Building on the extant e-government literature, the reintroduction of the original data into the framework yielded some emergent observations and insights for future e-government design, including the somewhat paradoxical importance of human contacts and interactions in electronic channels, service efficiency and process factors that impinge on customer satisfaction and dissatisfaction, and a potential growth trajectory for telephony based e-government for older segments of the community.

Services Evaluation

Appropriate performance evaluations of commercial Cloud services are crucial and beneficial for both customers and providers to understand the service runtime, while suitable experimental design and analysis would be vital for practical evaluation implementations. However, there seems to be a lack of effective methods for Cloud services performance evaluation. For example, in most of the existing evaluation studies, experimental factors (also called parameters or variables) were considered randomly and intuitively, experimental sample sizes were determined on the fly, and few experimental results were comprehensively analyzed. To address these issues, the authors suggest applying Design of Experiments (DOE) to Cloud services evaluation. To facilitate applying DOE techniques, this paper introduces an experimental factor framework and a set of DOE application scenarios. As such, new evaluators can explore and conveniently adapt our work to their own experiments for performance evaluation of commercial Cloud services.

Purpose – The purpose of this paper is to define an evaluation model for cloud services to deal with the fuzzy information and propose a novel fuzzy evaluation method based on consistency intensity to analyze the quantitative value from the fuzzy information. Design/methodology/approach – The cloud service evaluation framework is constructed, and different trusted indicators for the infrastructure services and the application services are designed, respectively. In the novel fuzzy evaluation method, the interval values can be aggregated by the Dempster-Shafer Theory and be transformed into the certain value by linguistic discount factor. The consistency intensity is proposed to determine the value of the linguistic discount factor, which can reflect the mainstream opinions in the assessment. Findings – The proposed method can solve the problem on the analysis and synthesis of the fuzzy evaluation information. An instance of trust evaluation of cloud storage service is illustrated to verify that the proposed method can express the opinions of all evaluators more adequately. Practical implications – A serial of experiments are carried out on NetLogo, and the results show that the proposed method is practical and efficient. Originality/value – Instead of obtaining only the qualitative results by the multi-attribute decision-making method, the fuzzy evaluation method based on consistency intensity can obtain the quantitative results from the fuzzy information according to linguistic discount factor and consistency intensity.

Innovation Patterns

The paper reflects about the need to introduce and develop approaches and tools for public services evaluation. Starting from the acknowledgment that investments in public services has dramatically increased over the last decade, we could state that they must also respond to new varieties of societal challenges and rising demands coming from service users. This pressure makes a strong push upon innovation considering that, if services must be designed to meet the complex needs of users, they also must reach a high rate of delivering cost efficiency.This article proposes an approach based on qualitative and quantitative measurements throughout the whole service design process in which service evaluation may represent a tool for value creation and a driver for innovation in public sector.Considering the emerging interest on evaluating design and innovation (OECD, 2010; European Commission, 2012) the authors try to explore existing evaluation methods for services in public sector, in order to define an evaluation framework that could support new innovation patterns.

The Impact

Evaluations of mental health outcomes have traditionally focused on indicators of mental health maintenance and stability. Although many jurisdictions in Canada are incorporating the principles of recovery into mental health services, evaluation practices and accountability frameworks have not kept pace with this shift in thinking. In our local regions of Waterloo and Wellington-Dufferin, Ontario, an innovative partnership between mental health agencies and consumer organizations has developed to apply principles of recovery to system-wide case management. In this article we describe the development of a comprehensive logic model framework designed to assess the impact of system-wide changes to practice. The model is grounded in the experiences, needs, and expectations of service users. This framework positions recovery-focused outcomes as alternatives to maintenance-based outcomes and as central to knowledge development and accountability in mental health systems.
