This chapter demonstrates how conjoint analysis can be used to improve the design and delivery of mass consumer information products. Conjoint analysis is a technique that market researchers have used since the 1960’s to better understand how buyers make complex purchase decisions, to estimate preferences and importance ratings for product features, and to predict buyer behavior. This chapter describes the steps for performing a conjoint analysis to assess information quality preferences of potential home buyers interested in using a real estate website to help them locate properties for sale. The author hopes that this tutorial will convince information systems professionals of the usefulness of conjoint analysis as a tool for discerning how to prioritize information quality requirements so that the resulting systems produce information products that better serve the needs of their customers.

This chapter presents a logical technology-independent fully content-focused inquiry into the operations quality problems of any symbolic representations of reality. This teleological operations-research-based approach demonstrates that a purpose-focused view, natural within the operation- research (OR) methodology, facilitates faster progress in identifying the fundamental relationships of more lasting validity for business, public administration, and military purposive operations. Products of the Information Quality Programs and Initiatives at MIT (MITIQ Program) serve as recognized research references. It contains definitions of (1)A tentatively universal hierarchical taxonomy of the entire universe of quality requirements, (2) The tentative definitions of the first five tentatively universal operations quality requirements for any situation, (3) An economic sequence of their examination, and (4) The first seven tentatively universal principles in this domain. This quality framework may assist researchers in further studies and assist practitioners in understanding the intricate relationships among operations quality attributes. The chapter presents the tentative results of the author’s research in progress.

Canada’s Health Informatics Association has been hosting annual conferences since the 1970’s as a way of bringing information systems professionals, health practitioners, policy makers, researchers and industry together to share their ideas and experiences in the use of information systems in the health sector. This paper describes our findings on the outcome of information systems implementation projects reported at these conferences in the 1990s. Fifty implementation projects published in the conference proceedings were reviewed and the authors or designates of 24 of these projects were interviewed. The overall experiences, which are consistent with existing implementation literature, suggest the need for organizational commitment; resource support and training; managing project, change process and communication; organizational/user involvement and teams approach; system capability; information quality; and demonstrable positive consequences from computerization.

Consumer Information Search

Understanding the nature of information quality in the context of consumer information search on a website is vital for Information Systems as well as for marketing managers who want to use their websites for strategic purposes. This study brings together the Information Systems (IS) Success Model and consumer information search literature to propose and test a comprehensive model investigating information quality, and extends the IS Success Model. Our model tests antecedents to and consequences of information quality of a website. Findings on data collected from 575 respondents reveal that perceived cost and self efficacy (among others) are significant antecedents to information quality. Findings also reveal that information quality significantly affects online WOM and trust, which has implications for managing users on social media as well as on websites. This study adds to the literature on IS and on consumer information search, and offers practical guidelines for managers.

Products evoke emotions in people. Emotions can influence purchase decisions and product evaluations. It is widely acknowledged that better product performance and higher user satisfaction can be reached through aesthetic design. However, when designing a new product, most of the attention is generally paid to enhance its functionality and usability and much less consideration is given to the emotional needs of users. This paper investigates the connection between emotions and product features. Various forms of vases are used as a product case. Additionally, a compact list of product-specific semantic descriptors is first developed using a classification based on Jordan’s four pleasures model. Paper-based surveys, face-to-face interviews, and statistical methods were performed in this paper, where significant correlations between semantic descriptors and product geometry were found. Prototypes of two vases were developed based on elicited emotions and a short validation on aesthetic value was performed. Our results show core set of geometric features of a vase have the strongest impact on emotional responses from users: the opening of the neck, the height of the neck, the base of the neck (width), and the base (width).

Background: Despite clinical recognition of the adverse effects of acquired hearing loss, only a small proportion of adults who could benefit use hearing aids. Hearing aid adoption has been studied in relationship to client-related and hearing aid technology–related factors. The influence of the client-clinician interaction in the decision to purchase hearing aids has not been explored in any depth. Purpose: Importance ratings of a sample of adults having a recent hearing aid recommendation (clients) and hearing healthcare professionals (clinicians) from across Canada were compared on factors in client-clinician interactions that influence hearing aid purchase decisions. Research Design: A cross-sectional approach was used to obtain online and paper-based concept ratings. Data Collection and Analysis: Participants were 43 adults (age range, 45–85 yr) who had received a first hearing aid recommendation in the 3 mo before participation. A total of 54 audiologists and 20 hearing instrument practitioners from a variety of clinical settings who prescribed or dispensed hearing aids completed the concept-rating task. The task consisted of 122 items that had been generated via concept mapping in a previous study and which resulted in the identification of eight concepts that may influence hearing aid purchase decisions. Participants rated “the importance of each of the statements in a person’s decision to purchase a hearing aid” on a 5-point Likert scale, from 1 = minimally important to 5 = extremely important. For the initial data analysis, the ratings for each of the items included in each concept were averaged for each participant to provide an estimate of the overall importance rating of each concept. Multivariate analysis of variance was used to compare the mean importance ratings of the clients to the clinicians. Ratings of individual statements were also compared in order to investigate the directionality of the importance ratings within concepts. Results: There was a significant difference in the mean ratings for clients and clinicians for the concepts understanding and meeting client needs, conveying device information by clinician, supporting choices and shared decision making, and factors in client readiness. Three concepts—understanding and meeting client needs, conveying device information by clinician, and supporting choices and shared decision making—were rated as more important by clients than by clinicians. One concept (ie, factors in client readiness) was rated as more important by clinicians than by clients. Conclusions: The concepts rated as most important by clients and clinicians are consistent with components of several existing models of client-centered and patient-centered care. These concepts reflect the clients’ perception of the importance of their involvement in the decision-making process. A preliminary model of client-centered care within the hearing aid uptake process and implications for clinical audiology are described.

Claims that, as an addition to the product manager’s set of tools, performance‐importance analysis can provide insight into customer perceptions. Managers can use a combination of performance perceptions along with importance ratings to understand the relative success of product features. Plots importances for product features of an analytical instrument against the product’s pre‐introduction expectations and post‐product‐test satisfactions. Considers product design issues as well as positioning strategy. Changes in evaluations (“expectations” to “satisfactions”) as well as competitive positioning demonstrated the flexibility of the method.
