Specify Measures
Specify measures to address measurement objectives. Measurement objectives are refined into precise, quantifiable measures. Measurement of project and organizational work can typically be traced to
one or more measurement information categories. These categories include
the following: schedule and progress, effort and cost, size and stability, and quality. Measures can be either base or derived. Data for base measures are
obtained by direct measurement. Data for derived measures come from
other data, typically by combining two or more base measures.
