8.1.3.3 Quality Metrics

A quality metric specifically describes a project or product attribute and how the control quality process will
measure it. A measurement is an actual value. The tolerance defines the allowable variations to the metric. For
example, if the quality objective is to stay within the approved budget by ± 10%, the specific quality metric is
used to measure the cost of every deliverable and determine the percent variance from the approved budget for
that deliverable. Quality metrics are used in the perform quality assurance and control quality processes. Some
examples of quality metrics include on-time performance, cost control, defect frequency, failure rate, availability,
reliability, and test coverage.

8.1.3.4 Quality checklists

A checklist is a structured tool, usually component-specific, used to verify that a set of required steps has
been performed. Based on the project’s requirements and practices, checklists may be simple or complex. Many
organizations have standardized checklists available to ensure consistency in frequently performed tasks. In some
application areas, checklists are also available from professional associations or commercial service providers.
Quality checklists should incorporate the acceptance criteria included in the scope baseline.

8.1.3.5 Project documents updates

Project documents that may be updated include, but are not limited to:
• Stakeholder register (Section 13.1.3.1); and

• Responsibility assignment matrix (Section 9.1.2.1); and
• WBS and WBS Dictionary.

8.2 Perform Quality Assurance

Perform Quality Assurance is the process of auditing the quality requirements and the results from quality
control measurements to ensure that appropriate quality standards and operational definitions are used. The key
benefit of this process is that it facilitates the improvement of quality processes. The inputs, tools and techniques,
and outputs of this process are depicted in Figure 8-8. Figure 8-9 depicts the data flow diagram of the process.
