This article investigates the complex nature of information in information systems (IS). Based on the systems thinking framework, this study argues that information in IS is a system in its own right. A conceptual model of information-as-system is built on the systems thinking perspective adopted from Gharajedaghi’s holistic thinking rooted from Ackoff systems approach, which is developed through Peirce’s semiotics with the validity support of Metcalfe and Powell’s perspective of information perception, Mingers and Brocklesby’s schema of situational actions, Toulmin’s theory of argumentation and Ulrich’s theory of systems boundary. The proposed model of information-as-systems is described in terms of triads–on the structure, function, and process, all interdependent–in a context of information-as-system in IS.

This work presents a conceptual model aimed at explaining factors affecting the formation of effective patient-doctor-computer communication at the primary care clinic. The authors define a new construct – patient-doctor-computer communication (PDCC), aimed to replace the traditional concept of dyad patient-doctor communication (PDC). PDC has been characterized as one of the most significant factors affecting healthcare outcomes. To better understand PDCC and its antecedents, the authors integrate theories from the patient-centered care and the Information Systems domains and suggest that the characteristics of the EMR, the user (doctor) and the task determine the doctor's perception of fit between the EMR and the medical task, which in turn positively affects PDCC. The suggested conceptual model contributes to both theory and practice. On the theoretical side, it opens several new research trajectories. For practice, the model implies that there is a need for a tighter collaboration between experts from both the information systems and medicine domains in designing EMR systems that are aligned with and support the medical task at hand.

Development of information systems in complex and dynamic organisations has failed in many aspects often due to the inability to manage complexity in interdependent enterprise and information systems changes. This paper presents some essential difficulties from the case project in systems development based on IT products like ERP products. We give an example of critical architectural issues where our understanding must increase to make a powerful management tool in business/enterprise and IT development. A conceptual model of actors and relations to support coordination of architecture from business perspective and IT supplier perspective is outlined.

The chapter presents an alignment framework and an associated representation framework for information systems (IS) architecture management. The alignment framework supports identification of high-level longer-term principles for evolution of IS architectures. The fundamental idea of the alignment framework is to generate alternative future IS architectures by grouping IS-architecture phenomena into IS-architecture areas in different ways. The representation framework supports the creation of IS-architecture models that can support IS-architecture alignment and other IS-architecture management tasks. In addition, the representation framework is a conceptual model for thinking about IS-architectures. Together, the alignment and representation frameworks constitute an early theory of IS architectures and IS-architecture work. They are part of a comprehensive methodology that results from several years of case and theory studies, tool developments, industrial projects and consulting.

<p>The purpose of this research was to determine the impact of the strategic alignment between information systems (IS) and marketing on business performance. The work of Chan (1992) was used as a point of departure. She had explored the fit between IS and business strategies and had used strategic orientation as a basis for determining the fit (alignment). Although the marketing literature did not reveal any measure for alignment, measures existed for market orientation. This appeared to be the approximate marketing equivalent of strategic orientation. Given the strategic nature of market orientation, it was decided to use it in addition to strategic orientation in order to calculate alignment. It was also decided to use marketing performance as an intermediary dependent variable. A conceptual model was devised which could be applied to the assessment of alignment according to either strategic orientation or market orientation. It consisted of three constructs: alignment, marketing performance and business performance. Implicit in this model was the calculation of alignment based either on strategic orientation or on market orientation. Two versions of the model would thus be tested. A mixed methods approach was adopted for the research. First, a qualitative phase of interviews with 36 respondents (the heads of information technology (IT)/IS and the heads of marketing of 18 companies) was conducted. The purpose was to obtain a deeper understanding of perceptions of alignment between IS and marketing, and to ascertain the different measures used for marketing performance and business performance. The findings served to refine the conceptual model and inform the second phase survey. The second phase was quantitative and consisted of a mail survey of heads of IT and heads of marketing of large New Zealand companies. In total 415 responses were received, 350 of them being pairs from 175 companies.  Pairs of responses were a requirement for the calculation of alignment. A new formula was developed for the calculation. This was used to calculate alignment according to both strategic orientation and market orientation. The data collected in the second phase were used to test the model, using both factor analysis and structural equation modelling. Statistically significant evidence was provided that indicated that the alignment between IS and marketing exerts a positive impact on both business performance and marketing performance, and that marketing performance exerts a positive impact on business performance. This is so, irrespective of whether alignment is calculated according to strategic orientation or market orientation. The value of the research lies in the development of a parsimonious model which measures the alignment between IS and marketing and the impact of that on business performance. It also lies in the development of a robust formula for the calculation of alignment. It further demonstrates the value of a cross-disciplinary approach which could have significant implications for both academic research and for practitioners. The potential impact on companies consists of the breaking down of the silo mentality; an emphasis on cross-functional teamwork, cross-functional training and job rotation; and an impact on organizational structure and culture.</p>

The paper considers application of an ontological approach to development and implementation of Electronic Flight Bag information systems (EFB). An ontology of EFB systems’ subject area with description of a conceptual model of EFB software application for take-off and landing characteristics calculations of aircraft has been developed. The ontology was formalized using Protégé software.
