How to prepare a systematic review of economic evaluations for informing evidence-based healthcare decisions: data extraction, risk of bias, and transferability (part 3/3)

Introduction: This article is part of the series “How to Prepare a Systematic Review (SR) of Economic Evaluations (EE) for Informing Evidence-based Healthcare Decisions” in which a five-step-approach for conducting a SR of EE is proposed. Areas covered: This paper explains the data extraction process, the risk of bias assessment and the transferability of EEs by means of a narrative review and expert opinion. SRs play a critical role in determining the comparative cost-effectiveness of healthcare interventions. It is important to determine the risk of bias and the transferability of an EE. Expert commentary: Over the past decade, several criteria lists have been developed. This article aims to provide recommendations on these criteria lists based on the thoroughness of development, feasibility, overall quality, recommendations of leading organizations, and widespread use

Enterprise Modeling Support for SOA Migration

The migration to a Service Oriented Architecture (SOA) is a complex undertaking in terms of aligning business and IT concerns as well as analysis of technical aspects, such as identifying legacy systems in need of wrapping. Conceptual modeling can be particularly helpful for supporting SOA migration in terms of (1) bridging the gap between business and IT concerns, and (2) analyzing the as-is and to-be IT infrastructures. In this paper, based on the identified requirements, we extend a language for IT infrastructure modeling, called ITML. Using an extensively documented SOA migration scenario we show how extended ITML, in tandem with other languages from the MEMO language family, can be used for SOA migration analysis. Finally, we provide a scenario-based comparison between the extended ITML and ArchiMate

THE IMPACT OF CULTURAL DIFFERENCES ON ENTERPRISE ARCHITECTURE EFFECTIVENESS: A CASE STUDY

We study how differences between organizational subcultures influence the effectiveness of the Enterprise Architecture (EA) function for steering the enterprise. In this paper, we contribute findings from a case study in a governmental organization. We derive seven propositions concerning the relation between cultural differences and EA effectiveness. For one, we suggest that cultural differences among the architects have a negative impact on the architects’ communication towards the management. In addition, our data suggest that the influence of cultural differences is indirect: communication defects and disagreement within the architecture board act as important intermediary factor

A Multilevel Model of IT Platforms for the Needs of Enterprise IT Landscape Analyses

Conceptual modeling supports analyses of IT artifacts and the enterprise action system they are embedded in. However, in this paper it is argued that for IT landscape analyses existing modeling approaches fall short due to, among others, (a) problems with accounting for specifics of the IT domain, e.g., an elaborate technical terminology with various hierarchy levels, and (b) inadequate support for automated analyses within and across those different levels. In this paper, the authors discuss how a designed multilevel model of IT platforms created using the multilevel modeling language FMMLx can help overcome these problems. To this end, limitations of IT platform models created with conventional, two-level modeling languages are shown. Furthermore, benefits resulting from the application of the selected multilevel modeling language are discussed
