Computer measurement and evaluation

This is the authors' abstract. We don't add key points for this paper.

Effort invested in computer measurement and evaluation is clearly increasing, but the results of this increasing investment may be unfortunate. The undeniable value of the results and the enthusiasm of participants may be leading to unrealizable expectations. The present artistry needs to be converted into a science for achieving a solid future; the most fruitful direction may be the synthesis of individual, empirical discoveries combined with testing hypotheses about performance relationships.
