Designing Effective Decision Support Using Decisional Guidance

This study explores the decision outcomes achieved by 122 subjects using a DSS for an insolvency decision making task. Decision quality improvements occur as a result of collaboration between the decision maker and the DSS at two crucial points in the decision making process. Firstly when the decision maker initially interacts with the DSS to generate a recommendation, and secondly when the decision maker decides whether to incorporate that recommendation into their decision. Good technology design will assist a decision maker to generate a high quality recommendation; however the ensuing acceptance or otherwise of the recommendation is what ultimately affects the decision outcome. The study encompasses exploration of DSS use, and how decision outcomes are subsequently impacted. The results show that providing decisional guidance, in particular suggestive guidance, helped novice decision makers produce higher quality recommendations; and that adoption of those recommendations improved decision quality. The results are consistent with the theoretical premise that a key design issue is providing appropriate guidance to fit the task and individual, rather than simply guidance per se. The results show decision performance is a function of both how the technology is designed and used; and whether the user incorporates the recommendation received into their final decision. DSS use is a necessary, but not sufficient, precursor to improved decision outcomes

Decisional guidance for computerised personal decision aid (ComPDA)

Recently, the existence of many computerized decision aids which support personal decision making have drawn massive attention to study how these aids really help the decision makers.Helping decision maker makes a particular decision has always been the major aim of decision aids.However, designing an effective decision aid is more than meet the eyes.Guidance portion of the interface design in decision aid cannot be taken lightly as it can influence the outcomes.This study acknowledges the needs to make sure the design of personal decision aids adhere to systematic investigation to achieve the sole goal of a ComPDA.In this paper eight ComPDAs were identified and comparedto extract the decisional guidance components for ComPDA. Accordingly, comparative analysis of the tools is further explained and illustrated

Towards a Design Methodology for Decision Support Systems

The authors propose the use of process models for DSS design. The kind of process models suggested are task structures and decision structures with simple graphical syntax and semantics. The process models form the basis for a coherent DSS design methodology, based upon the bounded rationality paradigm. The history of DSS and DSS design is discussed to form a theoretical position. The resulting methodology has been tested and evaluated in a laboratory experiment. The results of this evaluation will be used for continuous improvement of the methodolog

Higher education decision making and decision support systems

The authors illustrate several issues in decision support and decision support systems (DSS), state of the art research in these fields, and also their own studies in designing a higher education DSS. The final section contains our contribution in outlining the modules of the DSS, involving the present systems and databases of FSEGA and UBB, results and activities belonging to FSEGA students, teaching and research staff, to assist decisions for all the actors implicated in the processes, in various specific situations.decision support, decision support systems (DSS), higher education institutions, Information and Communication Technologies (ICT)

The effectiveness of virtual facilitation in supporting GDSS appropriation and structured group decision making

Since their introduction a quarter of a century ago, group decision support systems (GDSS) have evolved from applications designed primarily to support decision making for groups in face-to-face settings, to their growing use for “web conferencing,” online collaboration, and distributed group decision-making. Indeed, it is only recently that such groupware applications for conducting face-to-face, as well as “virtual meetings” among dispersed workgroups have achieved mainstream status, as evidenced by Microsoft’s ubiquitous advertising campaign promoting its “Live Meeting” electronic meeting systems (EMS) software. As these applications become more widely adopted, issues relating to their effective utilization are becoming increasingly relevant. This research addresses an area of growing interest in the study of group decision support systems, and one which holds promise for improving the effective utilization of advanced information technologies in general: the feasibility of using virtual facilitation (system-directed multi-modal user support) for supporting the GDSS appropriation process and for improving structured group decision-making efficiency and effectiveness. A multi-modal application for automating the GDSS facilitation process is used to compare conventional GDSS-supported groups with groups using virtual facilitation, as well as groups interacting without computerized decision-making support. A hidden-profile task designed to compare GDSS appropriation levels, user satisfaction, and decision-making efficiency and effectiveness is utilized in an experiment employing auditors, accountants, and IT security professionals as participants. The results of the experiment are analyzed and possible directions for future research efforts are discussed

Designing a Process Guidance System to Support User’s Business Process Compliance

Organizations define business processes specifying how employees should conduct their daily work. They require their employees to conform to defined process standards in order to avoid expensive mistakes and ensure the intended process outcomes. From a research perspective, process compliance has been primarily addressed by process-centric information systems supporting the execution of business processes. However, employees still have difficulties in being process compliant. What is missing is the direct support for users in the proper execution of business processes within the actual work environment. We follow a design science approach to address this gap and suggest a process guidance system supporting user’s business process compliance. Grounded by findings from existing guidance research, we derive meta-requirements and design principles of such systems and evaluate our artifact by two expert workshops discussing the proposed solution

Conceptualization and Typology of Guidance in Information Systems

Organizations use intelligent systems, a special kind of information system, to provide knowledge and guidance for their employees in their daily work. Concepts of guidance have been researched in the Information Systems community and related communities for decades. But due to the missing of a common concept and typology of guidance it is hard to compare the findings of the existing research streams. This paper extensively reviews and analyses the work on decisional guidance, explanations and on decision aids conducted in the last 20 years of research. Building on and grounded by the analyzed literature, a conceptualization and typology of guidance is proposed and discussed. In addition, the findings on positive and negative effects of guidance are outlined. This research contributes to both, research and practice. Researchers’ will be enabled (1) to describe their own work on guidance by using a set of terms predefined for the Information Systems research community and (2) to compare various research on guidance. Practitioners will be provided with a set of design guidelines in order to implement intelligent systems using various guidance effects in order to improve their processes and systems

Determining the psychometric properties of the Enhancing Decision-making Assessment in Midwifery (EDAM) measure in a cross cultural context

© 2016 Jefford et al. Background: The ability to act on and justify clinical decisions as autonomous accountable midwifery practitioners, is encompassed within many international regulatory frameworks, yet decision-making within midwifery is poorly defined. Decision-making theories from medicine and nursing may have something to offer, but fail to take into consideration midwifery context and philosophy and the decisional autonomy of women. Using an underpinning qualitative methodology, a decision-making framework was developed, which identified Good Clinical Reasoning and Good Midwifery Practice as two conditions necessary to facilitate optimal midwifery decision-making during 2nd stage labour. This study aims to confirm the robustness of the framework and describe the development of Enhancing Decision-making Assessment in Midwifery (EDAM) as a measurement tool through testing of its factor structure, validity and reliability. Method: A cross-sectional design for instrument development and a 2 (country; Australia/UK) x 2 (Decision-making; optimal/sub-optimal) between-subjects design for instrument evaluation using exploratory and confirmatory factor analysis, internal consistency and known-groups validity. Two 'expert' maternity panels, based in Australia and the UK, comprising of 42 participants assessed 16 midwifery real care episode vignettes using the empirically derived 26 item framework. Each item was answered on a 5 point likert scale based on the level of agreement to which the participant felt each item was present in each of the vignettes. Participants were then asked to rate the overall decision-making (optimal/sub-optimal). Findings: Post factor analysis the framework was reduced to a 19 item EDAM measure, and confirmed as two distinct scales of 'Clinical Reasoning' (CR) and 'Midwifery Practice' (MP). The CR scale comprised of two subscales; 'the clinical reasoning process' and 'integration and intervention'. The MP scale also comprised two subscales; women's relationship with the midwife' and 'general midwifery practice'. Conclusion: EDAM would generally appear to be a robust, valid and reliable psychometric instrument for measuring midwifery decision-making, which performs consistently across differing international contexts. The 'women's relationship with midwife' subscale marginally failed to meet the threshold for determining good instrument reliability, which may be due to its brevity. Further research using larger samples and in a wider international context to confirm the veracity of the instrument's measurement properties and its wider global utility, would be advantageous
