Scales of Measure: How to Quantify

This chapter focuses on scales of measure. Scales of measure are fundamental to Planguage. They are central to the definition of all scalar attributes that is, to all the performance and resource attributes. One must know the art of developing scales of measure for the performance and resource attributes, which are important to the organization or system. The chapter explains it is important to define a scale of measure for any system critical variable performance or resource attribute. Most scales of measure are tailored variations of a generally applicable set of scales. Once you have learned the general set, it becomes much easier to generate useful scales as needed for variations. Finally, defining a scale of measure is a teachable practical process. Scales of measure in requirements are the foundation of understanding any design or architectural impact on that requirement—both when it is being considered, and then when it is being implemented in practice.
