The purpose of Process and Product Quality Assurance (PPQA) is to provide staff and management with objective insight into processes and associated work products. A Support Process Area at Maturity Level 2.
The Process and Product Quality Assurance process area involves the following activities :

- Objectively evaluating performed processes, work products, and services against applicable process descriptions, standards, and procedures.
- Identifying and documenting noncompliance issues.
- Providing feedback to project staff and managers on the results of quality assurance activities.
- Ensuring that noncompliance issues are addressed.
The Process and Product Quality Assurance process area supports the delivery of high-quality products and services by providing project staff and managers at all levels with appropriate visibility into, and feedback on, processes and associated work products throughout the life of the project.

Specific Goals and Practices

SG 1 Objectively Evaluate Processes and Work Products
Adherence of the performed process and associated work products and services to applicable process descriptions, standards, and procedures is objectively evaluated.
- SP 1.1 Objectively Evaluate Processes.
Objectively evaluate the designated performed processes against the applicable process descriptions, standards, and procedures. Objectivity in quality assurance evaluations is critical to the success of the project. A description of the quality assurance reporting chain and how it ensures objectivity should be defined.
- SP 1.2 Objectively Evaluate Work Products and Services.
Objectively evaluate the designated work products and services against the applicable process descriptions, standards, and procedures. The intent of this subpractice is to provide criteria, based on business needs, such as the following:
. What will be evaluated during the evaluation of a work product?
. When or how often a work product will be evaluated?
. How the evaluation will be conducted?
. Who must be involved in the evaluation?

SG 2 Provide Objective Insight
Noncompliance issues are objectively tracked and communicated, and resolution is ensured.
- SP 2.1 Communicate and Ensure Resolution of Noncompliance Issues.
Communicate quality issues and ensure resolution of noncompliance issues with the staff and managers. Noncompliance issues are problems identified in evaluations that reflect a lack of adherence to applicable standards, process descriptions, or procedures. The status of noncompliance issues provides an indication of quality trends. Quality issues include noncompliance issues and results of trend analysis.
When local resolution of noncompliance issues cannot be obtained, use established escalation mechanisms to ensure that the appropriate level of management can resolve the issue. Track noncompliance issues to resolution.
- SP 2.2 Establish Records.
Establish and maintain records of the quality assurance activities. Typical Work Products are evaluation logs, quality assurance reports, status reports of corrective actions and reports of quality trends.
