PB-ISAM : a process-based framework for information systems effectiveness assessment in organizational contexts

Özkan, Sevgi
A number of approaches of assessment associated with IS effectiveness have been examined, fundamental guidelines for research in this area have been derived, and a novel model of IS effectiveness has been proposed. A process based assessment method (PB-ISAM) based on the proposed effectiveness model has been elaborated. The new model and the new assessment method have been evaluated via three case studies. Specific implications have been drawn concerning the relationships between processes and the information system assessed. The three case studies have provided insight into the IS effectiveness field and for future work.


Process based information systems evaluation: Towards the attributes of "pRISE"
Özkan Yıldırım, Sevgi; Bilgen, Semih (2007-10-31)
Purpose The purpose of this paper is to demonstrate the importance of undertaking a systemic view of information systems evaluation that augments the frequently reported prescriptive (cost/benefit) analysis approaches. Design/methodology/approach The paper adopts a qualitative case perspective and derives a framework for substantive information systems evaluation factors (PRISE). Three empirical formulations are considered and a comparison made to determine the content and context of the findings. Finding...
Evaluating learning management systems: Hexagonal e-learning assessment model (HELAM)
Ozkan, Sevgi; Koseler, Refika; Baykal, Nazife (null; 2008-12-01)
A considerable amount of research has been conducted on evaluating success of information systems. However, there has been little research addressing the conceptualization and measurement of elearning systems success within educational organizations. Evaluation of information systems within the growing e-learning sector is currently receiving attention, and this research study proposes a conceptual e-learning assessment model, HELAM (Hexagonal e-Learning Assessment Model). HELAM has been applied to 23 e-lea...
A method for decentralized business process modeling
Türetken, Oktay; Demirörs, Onur; Department of Information Systems (2007)
This thesis study proposes a method for organizations to perform business process modeling in a decentralized and concurrent manner. The Plural method is based on the idea that organizations’ processes can be modeled by individuals actually performing the processes. Instead of having a central and devoted group of people to understand, analyze, model and improve processes, individuals are held responsible to model and improve their own processes concurrently. These individual models are then integrated to f...
Using boolean- and fuzzy-logic-based methods to analyze multiple case study evidence in management research
Oz, O (SAGE Publications, 2004-06-01)
The case study method has been widely used as a research strategy in the management field. The issues of comparability and of generalizability when using this method, however, continue to raise profound challenges for researchers. Boolean- and fuzzy-logic-based methods offer a valuable basis for a contribution in this respect because they enable researchers to derive valid meaning from data and to introduce additional analytical rigor into case study research. Inspired by this opportunity, the present artic...
Assessing hospital information systems processes: a validation of prise information systems success model in healthcare
Ozkan, Sevgi; Baykal, Nazife; Sincan, Murat (null; 2008-12-01)
Although there is limited research and evidence base, it is reasonable to expect that high quality information technology is an integral factor in the success of today’s health care sector. However, the health care sector is considered to be low level investor in Information Technology (IT) when compared to other sectors. There are studies that look at the sums spent on health IT as a basis for determining how effective the IT systems are. We support the idea that the effectiveness of IT systems, is not an ...
