1. Measurement is done on the defined Scale, with respect to specified Qualifier Conditions.
2. Measuring is done using defined Meters.
3. Measuring is distinct from quantification and estimation. Quantification is merely defining an Attribute with the help of a Quantification-Scale, and Benchmarks and/or target values. Estimation is trying to determine future results based on Past data.
