An Integrated Quality Assurance Framework for Specifying Business Information Systems

The software specification acts as a bridge between customers, architects, software developers and testers. If information gets lost or distorted when building this bridge, the wrong system will be built or the system will not be built in time and budget⎯or both! Standards and recommendations give advice on how to structure specifications or check software-engineering artefacts with reviews or ...

A Quality Assurance Approach to Healthcare: Implications for Information Systems

Despite decades of research, healthcare information systems have been characterised by cost over-runs, poor specifications and lack of user uptake. A new approach is required which provides organisations with a reason to invest in this type of software. W Edwards Deming argues that quality is not an entity but derives from using feedback, iteratively to seek improvement to processes, in order t...

A Systems Approach to Information Technology (IT) Infrastructure Design for Utility Management Automation Systems

Almost all of electric utility companies are planning to improve their management automation system, in order to meet the changing requirements of new liberalized energy market and to benefit from the innovations in information and communication technology (ICT or IT). Architectural design of the utility management automation (UMA) systems for their IT-enabling requires proper selection of ...

RELATIVE INFORMATION FUNCTIONAL OF RELATIVE DYNAMICAL SYSTEMS

 In this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. We extract the information function ofan ergodic dynamical system (X,T) from the relative information of T fromthe view point of observer χX, where X denotes the base space of the system.We also generalize the in...
