SQA (via IEEE)
A planned and systematic pattern of all actions necessary to provide adequate confidence that an item or product conforms to established technical requirements.
A set of activities designed to evaluate the process by which products are developed or manufactured. Contrast with: quality control (1).

11. SW-CMM Key Practices for Software Quality Assurance
A SQA plan is prepared for the SW project ATADP.
The SQA group’s activities are performed IAW the SQA plan.
The SQA group participates in the preparation & review of the project’s SW dev plan, standards, & procedures.
The SQA group reviews the SWE activities to verify compliance.
The SQA group audits designated SW work products to verify compliance.
The SQA group periodically reports the results of its activities to the SWE group.
Deviations identified in the SW activities & SW work products are documented & handled ATADP.
The SQA group conducts periodic reviews of its activities & findings with the customer’s SQA personnel, as appropriate.

13. Ensure Quality Objectives are Defined for the Project
The Project Manager may not necessarily define the quality goals for the project, but ensures that these definitions are created and agreed by the customer, and captured ultimately in the Software Requirements Specification. The developing organization may also have a standard set of quality goals, in a quality policy statement, which can form the basis for these definitions.
Where possible, these objectives should be described in measurable terms. For example:
"Zero known severity 1 defects" (...and include a definition of a severity 1 defect)
"Maximum 3 second response time"
"User can pick up software and begin entering account information within 1 hour"

14. Define Quality Assurance Roles and Responsibilities
The next step is to define the organization, roles and responsibilities that will participate in these tasks.
This should include the reporting channel for the results of Quality Assurance reviews.
In many situations, the Quality Assurance task should submit its reports directly to the Project Review Authority.
The Rational Unified Process recommends that the Software Engineering Process Authority (SEPA) should have responsibility for the process aspects of quality, and perform process reviews and audits, as well as ensuring the proper planning and conduct of the review events described in the Review and Audit section of the Quality Assurance Plan.

15. Coordinate With Developers of Referenced Plans
The Quality Assurance Plan also references a number of other plans describing project standards and how various supporting process (e.g. configuration management) to be handled.
This information is used to help determine the types of Quality Assurance reviews that will be done, and their frequency.
The referenced plans would normally include the following:
Documentation Plan
Measurement Plan
Risk Management Plan
Problem Resolution Plan
Configuration Management Plan
Software Development Plan
Test Plan
Subcontractor Management Plan

16. Define Quality Assurance Tasks and Schedule
Identify the tasks of Quality Assurance. Typically these reviews would include:
Audit/review of project plans to ensure they follow the defined delivery process for the project.
Audit/review of project to ensure the work performed is following the project plans.
Approval of deviations from the standard organizational project processes.
Process improvement assessments
The Project Review Authority and Project Manager together determine the schedule for Quality Assurance reviews and audits, and the schedule is captured in the project and iteration plan, which may then be referenced from the Quality Assurance Plan.
The contract may also allow the customer to request audits.

SQA processes provide assurance that the
software products and
processes
in the project life cycle
conform to their specified requirements
by planning, enacting, and performing a set of activities to provide adequate
confidence
that quality is
being built into
the software.
