Digital platforms characterized by network effects enable provisioning of various types of services and provide a mechanism for linking producers and consumers. Identifying the key Quality of Service attributes of such platforms is vital for their continued success and growth. In this paper, a set of quality attributes for platforms is first extracted from different extant quality models. Then actual user feedback data from three platform providers are analysed and mapped against the set of quality attributes to determine the key attributes that are relevant. These findings are corroborated with qualitative data from interviews of different stakeholders. The results show that service quality characteristics are important to the success of platforms. Functional characteristics of platforms assume importance where the digital contributions of the platform is higher. Apart from these, 'fitness for use' as a major determinant of quality is also important in digital platforms.

e-Learning can be seen as not only one of Internet based information systems which can provide education services, but also one of teaching-learning methods which can implement self-directed learning. This paper tests factors affecting the e-Learning performance based on information systems success model and self-efficacy theory using a field study. Questionnaires are collected from 216 students who are enrolling a e-learning class using online survey. The results are following: first, the service quality and self-efficacy are significant predictors of use intention, but system quality and information quality are not. second, the system quality, information quality, service quality and self-efficacy are significant predictors of user satisfaction. Third, use intention and user satisfaction are found to be a strong predictor of the learning performance.

The purpose of this study is to investigate the perceived quality toward user performance and corporate performance in production information systems. For this purpose, a research model and hypotheses are developed based on the relevant literature reviews. Data have been collected from 132 enterprises which have implemented production information systems, and the research hypotheses were tested by covariance structural model analysis. The results of this empirical study are summarized as follows. First, production information quality and support service quality are confirmed to have a positive effect on user's satisfaction, however, I found no evidence of a statistically significant relationship between system quality and user's satisfaction. Second, all of three quality factors which are production information quality, system quality, and support service quality have positive influence on system usage. Third, user's satisfaction has positive influence on system usage, and both of user's satisfaction and system usage have positive influence on performance improvement. Based on these findings, this study suggested the implications, as well as limitations and further research directions.

Along with the significance of information systems in today s global business operation, the significance of information systems control and audit is ever increasing in the effort to secure accuracy and integrity of vital business data. A study is undertaken to integrate Food and Drug Administration computerized systems validation regulations. Securities & Exchange Commission Sarbanes-Oxley Act of 200 and other significant regulations, and lastly, People Capability Maturity Model into one comprehensive information system validation model. The initial benefits to this comprehensive model are convenience, time-saving, and synchronization of the regulations. An organization that is striving for a high level of quality system in its essential operating areas of organization may opt for this model. After the complete development of the model, a field test would be scheduled to test its efficacy and validity.

The customer requirements are constantly changing in the hyper-competition and competition is becoming increasingly intensified. In order to ensure the competitive advantage in the industry should focus on the management activities to enhance customer satisfaction. High quality means pleasing customers, not just protecting them from annoyances. It is due to continuous and requires the establishment of a quality management system that meets the characteristics and systematization need to manage a stable quality and productivity, which should be done in a company-wide quality management activities. The purpose of this study is to identify a suitable organizational diagnostic model for considering to adopt ISO 9001 quality management systems. We used the three-round delphi techniques on a panel of 30 experts. A total of 26 assessment indicators were developed through this panel. First, it is important to evaluate the strategy about quality. Second, it is important to evaluate the systems about periodically communicating quality agenda. Third, it is important to evaluate the responsibility of overall business process. In conclusion, this study empirically shows how firms can develop an organizational diagnostic model to increase their quality management systems.

For reliability and confidentiality of information security systems, the security engineering methodologies are accepted in many organizations. To improve the effectiveness of security engineering, this paper suggests a security methodology ISEM, which considers both product assurance and production processes, takes advantages in terms of quality and cost. To verify the effectiveness of ISEM, this paper introduces the concepts of quality loss, and compares the development costs and quality losses between ISEM and CC through the development of VPN system.

Single PPM Quality Innovation Movement is originally developed quality program in Korea for supplier's quality level-up since 1995. The quality target is below the 10ppm(parts per million) in outgoing quality and delivered goods plus field claim. Recently 1,053 companies is received Single PPM Quality Certification from government. This quality program is to realized the anticipated results not only duality level's increasing, but also company's confidence, competitiveness. We were able to obtain participations of 75 questionnaire, and derived statistics by means of SPSS/PC version 10.0. In this study, we find the bottleneck factor for promotion and upgrade S-PPM, and suggest a way out of difficulties.

This study explores the reporting tendencies of project managers when sending a status reports to their respective senior managers in information systems development project. It also examines the effect of selective reporting on report quality and systems development performance. The research model is proposed based on literature survey as well as key points from Iacovou et al. [2009] which is an extension of selective reporting in information systems project. Analysis of responses from 257 project managers in information systems industry indicates that pessimistic reporting by project managers has negative effect on both report quality (mediator variable) and systems development performance, while optimistic reporting has no significant effect on systems development performance. The CEO interest has an impact on the senior manager's power, which in turn leads to optimistic reporting by project managers. The senior manager's character has an impact on the senior manager's leadership, which in turn leads to pessimistic reporting. No direct relationship exists either between CEO interest and optimistic reporting or between senior manager's character and pessimistic reporting. In addition, trust toward the senior managers is significantly related to pessimistic reporting. Finally, report tendencies are also found to be affected by the active/passive characteristics of project managers.
