Abstract

Technological advances in the field of information and interactive systems mean that increasing numbers of factors and criteria are considered to assess quality during the design, development and evaluation process. In this context, concepts such as quality of use and user experience have appeared and in many cases are replacing or supplementing existing usability properties to identify the quality of the interaction process. In this paper we describe and analyze the evolution of the different concepts to identify the quality of the interaction on information systems and we help to characterize and locate each quality factor in one dimension and a specific range of the process of use, and consider the relationships and overlap between these concepts.

Abstract

Project risk evaluation complexity demands modern information systems that increase objectivity and are more visual, intuitive, and flexible. Thousands of construction projects have been analyzed to define a risk system that fulfills these requirements and uses a new kind of risk indicator: The Visibility factor. This indicator makes it possible to get quantitative values for any risk and to summarize risk scenarios. The system is analytical and the result is visual in order to allow the risk level to be identified at any stage, making it much easier for decision-makers to determine the best possible option. Risk data is collected via multiple choice questionnaires, built over a template, and the sections are weighted based on the project characteristics and its circumstances. This system can be used in any industry by modifying the questionnaires and it has been tested in a Spanish IBEX-35 construction company.
