Funmi Adebesin, Paula Kotzé, Derek Ritz, Rosemary Foster, Darelle van Greunen. 2014. A method for selecting e-health standards to support interoperability of healthcare information systems. In: Proceedings of IST Africa 2014, eHealth Thematic Area, Dublin: IIMC International Information Management Corporation Ltd, ISBN: 978-1-905824-43-4, 11 pages (No page numbers - electronic proceedings)

There is growing concern over the fragmentation and inability of healthcare information systems (e-health systems) to exchange pertinent healthcare information that can empower healthcare professionals to make informed decisions regarding the care of their patients. Standardisation is increasingly being seen as a means to ensure the interoperability of e-health systems. However, several e-health standards are being published, many of them without implementation guidelines. This paper describes a proposed method that could guide the selection of e-health standards (particularly for developing countries) to support the interoperability of e-health systems. A draft version of the paper is available here.

Paula Kotzé and Rosemary Foster. 2014. A conceptual data model for a primary healthcare patient-centric electronic medical record system. In: Proceedings of the IASTED African Conference on Health Informatics (Africa HI 2014), edited by N.M. Seboni and M.N. Tanko. Acta Press. ISBN: 978-0-88986-970-7, P. 245 - 250.

The development and use of national guidelines for the exchange of patient-centric healthcare data from electronic medical record systems are essential for the consistent and efficient use and analysis of those data. These guidelines must be based on a core national data model. This paper proposes a basic conceptual data model for primary healthcare patient-centric electronic medical record systems, derived for the South African district health system context, which would provide a suitable set of information to ensure continuity and longitudinality of patient-centric healthcare information. The data model was compiled based on the characteristics of the district –based primary healthcare model, data collected from best practices internationally regarding continuity of care, typical healthcare protocols, a study of public healthcare district hospital information systems and both public and private primary healthcare information systems. A draft version of the paper is available here.

Jan Mentz, Paula Kotze‚ & Alta van der Merwe. 2014. Propositions that Describe the Intended Meaning of Enterprise Architecture. In: Empowered by Technology – Proceedings of SAICSIT 2014, edited by JP van Deventer, MC Matthee. H Gelderblom and A Gerber. ACM Press, ISBN: 978-1-4503-3246-0, p 304 - 313.

In scientific inquiry definitions serves the purpose of describing what something is in terms that are concise, precise and allows for clear communication. Since the start of the enterprise architecture (EA) research field the issue of the definition of terms and fundamental concepts has been continually debated. The ongoing debate is indicative of a lack of universal agreement on EA fundamentals amongst EA researchers and practitioners which, in turn, manifests as a gap in the literature with regard to the underlying fundamental concepts of EA. This paper reports on the results of an investigation into the description of EA‘s fundamental concepts. During the investigation a structured interpretation method was applied to two prominent enterprise architecture frameworks in order to produce a set of EA propositions that captured the fundamental meaning of EA as a concept. The investigation resulted in the ‗EA claim‘ that EA is similar, in intent, to the enterprise as a worldview is to the world. The ‗EA claim‘ and its supportive six EA propositions provide and explicit description of the foundational understanding of what EA is. A draft version of the paper is available here.

T.1 PhD Thesis

Motseothata Petrus (Motse) Tsogang. 2014.  A Framework for Creating Patterns and Pattern Languages for Enterprise Architecture. PhD in Computer Science, University of South Africa.

Supervisor: Paula Kotzé

Co-supervisor: Alta van der Merwe

Abstract:

The development and maintenance of enterprise architecture (EA) is a complex recurring problem, which needs description in terms of the underlying rules and principles as they relate to the entire process. The biggest challenge facing enterprises is the management of change and complexity, as well as keeping up with the needs of the ever-changing enterprise environment.  Patterns and pattern languages could add value to EA by bringing a wealth of reusable solutions to the problems of managing the change and complexity faced by enterprises. However, the use of patterns and pattern languages in EA is a relatively novel concept. Although the concepts of patterns, pattern languages and EA are all over 30 years old, the idea of applying patterns in EA is hardly explored. Only a small number of patterns and pattern collections that are specifically aimed at EA, are available in the public domain. Furthermore, no framework or method exists to guide the creation of patterns and pattern languages for EA.  The purpose of this study is to develop a Pattern Framework for Enterprise Architecture (PF4EA), which can guide the development of well-grounded patterns and pattern languages for the practices of EA. The framework consists of a conceptual model and a method to populate the various components of the model in order to produce a set of patterns, which are collated into a pattern language. PF4EA is grounded in EA as well as in pattern and pattern language fundamentals. The PF4EA conceptual model consists of 11 components grouped into five different layers, which are devoted to addressing the various aspects of patterns, pattern languages and EA. The process of creating PF4EA firstly comprised the contextualisation of a theoretical foundation for patterns, pattern language and EA. Secondly, it involved consideration of the context-specific rules and properties associated with patterns, pattern languages and EA. Thirdly, it included the conformance to the context-specific pattern relationships. Fourthly, it comprised the creation of patterns for EA. Finally, the connecting of individual stand-alone patterns for EA into a pattern language for EA was considered.

Boroto Hwabamungu. 2014. The influence of stakeholder relations on the implementation of information systems strategy in public hospitals in South Africa: an activity theory perspective. PhD in Information Systems, University of Cape Town.

 Abstract:

Literature reveals that there exists a research gap between the development of information systems (IS) strategy and the implementation thereof. There is also a need for further research regarding the implementation of IS strategy in public hospitals in South Africa. The exploration of implementation in the context of public hospitals in South Africa, a country with many good policies and strategies that have been developed but that are not always implemented, is highly relevant.
In this study we undertook to explore the intricacies of stakeholder relations and the implications of these relations on the implementation of IS strategy in public hospitals in South Africa. This research was interpretive following a case study approach. Two provinces of South Africa were selected as cases: the Western Cape province and the Kwazulu Natal province. The Activity Analysis and Development (ActAD) framework, an enhanced form of activity theory, was used as the theoretical framework. Data was collected using semi-structured interviews, meetings,
documents analysis and physical artefacts observation. The collected data was analysed using thematic analysis.

 

The findings of this study reveal that factors related to stakeholder relations include the situational stakeholder relations dynamics and the level and motive of involvement in IS strategic activities and IS strategy operationalization processes at the different hierarchical levels. These factors affect the implementation of the IS strategy in public hospitals in South Africa by influencing different elements of the IS strategy implementation activity system. In the end we developed a framework, the stakeholder relations’ influence (SRI) framework which depicts the influence of stakeholder relations on the implementation of IS strategy in public hospitals in South Africa.
