Appendix B—Evolution of the OPM3 Standard

approved it. It was decided that the Model would describe how these
processes can be made "capable" through the four process improvement
stages: standardize, measure, control and continuously improve. This con-
struct would be used to organize all of the Capabilities of the Model.

B.7 HOUSE OF QUALITY

In this same face-to-face meeting, the Guidance Team identified all of the
design components of the Model. The team then evaluated each design
component against the requirements identified by the surveys of the mar-
ketplace. This was done through a voting process using techniques called
Quality Function Deployment and House of Quality. The House of Quality
or "HoQ" is an implementation of Quality Function Deployment that pro-
vides focus on customer requirements and correlation of all activities to sat-
isfy these requirements. Use of the House of Quality approach successfully
captured the following information:
■ The benefits that customers would want OPM3 to deliver were estab-
lished via a survey. This established HoQ Room 1;
■ Through market research and analysis, the team established an under-
standing of the customers and other models in the marketplace. This
established HoQ Room 2;
■ Via analysis, the team established a set of design attributes for OPM3.
This established HoQ Room 3;
■ Through a survey, the team determined the priority ranking of the cus-
tomer requirements. This established HoQ Room 5;
■ Via analysis, the team completed pair-wise comparisons of the rank-
ordered customer requirements (Room 1/Room5) against the OPM3
design attributes (Room 3) to populate Room 4, which depicts the
importance of each design attribute vis-à-vis the customer requirements.
This established HoQ Room 4.
■ Via analysis, the team evaluated all of the design attribute importance
data in Room 4 to deduce a priority order for the OPM3 design attrib-
utes (Room 6).
■ Room 6 compared OPM3 to other models for the purpose of bench-
marking. The results of this comparison provided assurance that OPM3
is at least equal to, and probably superior to, other models in the mar-
ketplace. This provided HoQ Room 7.
■ Via analysis, the team completed pair-wise comparison of the design
attributes to determine if providing any pair of Capabilities/functional-
ities results in synergies or the need to trade off what can be accom-
plished. This effort was completed for the highest priority design
attributes and populated HoQ Room 8.

B.8 ALPHA TESTING OF OPM3
By April 2002, the team had planned an OPM3 Testing Strategy. The Alpha
Testing, led by Clarese Walker, was a series of tests designed to assure that
the Model met the House of Quality standards. The first round of testing
looked at the content of the Best Practice and its Capabilities, Outcomes
