A measurement method is a logical sequence of operations, described generically, used in quantifying an attribute with respect to a specified scale. The operations may involve activities such as counting occurrences or observing the passage of time. The same measurement method may be applied to multiple attributes. However, each unique combination of an attribute and a method produces a different base measure. Some measurement methods ay be implemented in multiple ways. A measurement procedure describes the specific implementation of a measurement method within a given organizational context
