The recent release of CMMI V1.3 incorporates a number of changes to the model and framework; one of the more interesting is the decision to do away with Capability Levels 4 and 5 in the Continuous Representation, while retaining the high levels of Organizational Maturity. This paper examines some of the issues that may have driven this decision, and explores the opportunity provided for greater...

In this paper, a formal approach is taken to organize the body of knowledge about quality. The body of knowledge thus formalized is structured into: TOVE Quality Ontology, and the ISO 9003 Micro-Theory. The TOVE Quality Ontology represents a prototype formalization, researched from ISO 9000 and other quality management references, but independent of any one source. And the ISO 9003 Micro-Theory...

The main problems of standards (e.g., ISO 9241) in the context of usability of software quality are, that they can not measure all relevant product features in a task independent way. We present a new approach to measure user interface quality in a quantitative way. First, we developed a concept to describe user interfaces on a granularity level, that is detailed enough to preserve important in...

According to ISO 9241, traditional usability definitions focus on pragmatic aspects of technical systems, such as the ease of using a system (effectiveness, efficiency) and the perceived usefulness. While this definition was found to be highly applicable for a wide range of technical systems in the working context, it is a major question if the pragmatic approach is adequate for novel technical...

In this paper we present evaluation results of an innovative application designed to make collaborative design review in the architectural and automotive domain more effective. Within IMPROVE, a European research project in the area of advanced displays, we are combining high resolution multi-tile displays, TabletPCs and head-mounted displays with innovative 2D and 3D Interaction Paradigms to b...

OBJECTIVES To systematically review and analyze the current status and characteristics of usability studies in China in the field of information technology in general and in the field of healthcare in particular. METHODS We performed a quantitative literature analysis in three major Chinese academic databases and one English language database using Chinese search terms equivalent to the conce...

a mathematical model for commercial naphtha catalytic reformer of tehran refinery was developed. this model includes three sequencing fixed beds of pt/al2o3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of c6 to c9 hydrocarbons. the reaction network consisted dehydrogenation, hydrogenation...

In an increasingly wired world, digital libraries are increasingly serving a worldwide audience. Even if initially designed for a local user population, a digital library can easily fi nd itself not only serving its own community and culture, but also representing that society to a larger, international audience. As ”cultural ambassadors” to the world (Komlodi, Caidi & Wheeler 2004, 585), then,...
