The measurement of information systems effectiveness

ACM SIGMIS Database: the DATABASE for Advances in Information Systems, 1995
Information system effectiveness is an important phenomenon for both researchers and practitioners. Despite widespread interest, and the importance of the uses, there have been no efforts to validate Computerworld's Premier 100 rankings of information system effectiveness.

A Model for Measuring Information System Size

MIS Quarterly, 1991
Management of the software development process requires a thorough understanding of the environment in which development takes place. Ability to estimate, plan, and manage resource consumption is limited by the central problem of determining the size of system specifications.

Analysis and Synthesis of Information Systems with Information Relationships and Measures

1998
Analysis of relationships between information streams is of primary importance for analysis and synthesis of discrete information systems. This paper defines and discusses various information relationships and measures for the strength and importance of the information relationships.

Information measuring systems in nanotechnology

Automatic Documentation and Mathematical Linguistics, 2010
An overview is given of information measuring systems that are used in nanotechnology, which include devices such as scanning electron microscopes, scanning atomic microscopes, scanning atomic force microscopes, and manipulating tools. Their physical characteristics are described, and examples of their use in robotic nanoassembly are given.

Information System Concepts for Quality Measurement

Medical Care, 2003
Health care information systems in use today frequently fall short of what is needed to meet the demands for data and reporting on performance. Many observers believe substantial improvements in information systems will be necessary if the potential of a national quality measurement and reporting system (NQMRS) is to be realized.

Associating Data in System of Systems Using Measures of Information

Journal of Aerospace Information Systems, 2011
Many modern day collaborative systems/system of systems rely heavily on the sharing of information in order to improve performance, manage resources, and maximize overall capability. These types of systems are characterized by many decentralized nodes that can either all be identical or partitioned into a finite set of specialized types.

Measuring and Improving Quality Using Information Systems

1998
Information systems (IS) are increasingly important for measuring and improving quality. In this paper, we describe our integrated delivery system's plan for and experiences with measuring and improving quality using IS. Our approach is that for quality measurement to be practical, it must be integrated with the routine provision of care, and ...

Measuring quality of information systems

Omega, 1993
As stressed in earlier chapters, measurement is a key ingredient in the managerial process. Without measurement, no coherent evaluation of corporate performance, or indeed the performance of any part of the organization, can take place and no rational decisions can be undertaken. We have seen quite a few examples of how measurement of the wrong things,

Information Measures for Discrete Systems

2018
In this chapter, we define Shannon’s information measures for discrete-time discrete-alphabet systems from a probabilistic standpoint and develop their properties. Elucidating the operational significance of probabilistically defined information measures vis-a-vis the fundamental limits of coding constitutes a main objective of this book; this will be ...

Outcome Measures in Clinical Information Systems Evaluation

2004
Systems developed through informatics methods can be evaluated at different levels, depending on the purpose of the evaluation. A key class of measures useful in relating information systems to the quality of patient care is benefit or outcome measures, which reflect differences in the health or welfare of the patient that result from the system being ...
