| Web Quality Measurement and Evaluation based on Metrics and Indicators |
by Luis Olsina
A common challenge faced by many software and Web organizations is to have a clear establishment of a measurement and evaluation framework for quality assurance programs. In addition, organizations could succeed if resulting measurements and evaluations are tailored to their information needs for specific purposes, contexts, and user viewpoints. A well-established measurement and evaluation framework must rely on a sound conceptual (ontological) base. In this tutorial, we discuss our measurement and evaluation framework so-called INCAMI (Information Need, Concept model, Attribute, Metric and Indicator), which is based on a metrics and indicators ontology. Without appropiate definitions (metadata) of metrics and indicators it is difficult to ensure data values are repeatable and comparable among organization’s projects. Moreover, inter and intra-project analyses and comparisons could be performed in an inconsistent way. The tutorial aims to bring the attention of participants about the usefulness of this framework and strategy, in addition to discuss why INCAMI can be a more robust and well-established framework than the GQM (Goal-Question-Metric) paradigm for measurement and evaluation purposes. In order to illustate the main concepts, an E-commerce example is developed. The strengths and weaknesses of this framework are analysed as well.
