Bondavalli A., Ceccarelli A., Falai L., Vadursi M. Foundations of measurement theory applied to the evaluation of dependability attributes. In: 37th Annual IEEE/IFIP International Conference on Dependable Systems and Networks. DSN'07 (Edinburgh, UK, 25-28 June 2007). Proceedings, pp. 522 - 533. IEEE Computer Society, 2007.
Increasing interest is being paid to quantitative evaluation based on measurements of dependability attributes and metrics of computer systems and infrastructures. Despite measurands are generally sensibly identified, different approaches make it difficult to compare different results. Moreover, measurement tools are seldom recognized for what they are: measuring instruments. In this paper, many measurement tools, present in the literature, are critically evaluated at the light of metrology concepts and rules. With no claim of being exhaustive, the paper emph{i)} investigates if and how deeply such tools have been validated in accordance to measurement theory, and emph{ii)} tries to evaluate (if possible) their measurement properties. The intention is to take advantage of knowledge available in a recognized discipline such as metrology and to propose criteria and indicators taken from such discipline to improve the quality of measurements performed in evaluation of dependability attributes
