2. Content Background and history Implementations of ISO/IEC 15939

3. Motivation to write a standard
Measurement described inconsistently in existing software engineering standards
Several disjoint measurement standards
Need for common terminology and framework to communicate measurement information

4. Introduction
Continual improvement requires change within the organization.
Evaluation of change requires measurement.
Measurement itself does not initiate change.
Measurement should lead to action and not be employed purely to accumulate data.
Measurements should have a clearly defined purpose
Standard defines a measurement process applicable to system and software engineering and management disciplines.
Standard defines the activities of the measurement process to adequately specify
What measurement information is required
How the measures and analysis results are to be applied,
How to determine if the analysis results are valid.

8. Measurement Process Outcomes
Organizational commitment will be established and sustained
The information needs of technical and management processes will be identified
An appropriate set of measures, driven by the information needs, will be identified and/or developed
Measurement activities will be planned
The required data will be collected, stored, analyzed, and the results interpreted
Analysis results will be used to support decisions and provide an objective basis for communication
The measurement process and measures will be evaluated and improvements communicated to the process owners
