Presentation Abstract

A theory of measurement must take into account at least 8 factors:

• The attribute to be measured
• The appropriate scale for the attribute
• The variation of the attribute
• The instrument that measures the attribute
• The scale of the instrument
• The variation of measurements made with this instrument
• The relationship between the attribute and the instrument
• The likely side effects of using this instrument to measure this attribute

Software-related measurements often involve psychological or subjective components. They are questionable when they fail to take these factors into account. This paper describes the factors and uses the history of perceptual measurement to illustrate the application of them.
