I) analyses and corrects the systemic reasons for quality failures
Without measurement, there can be no control of quality.
TESTING is the set of activities by which QC does the measurement.
Testing "work products" need not be restricted to testing executable program code ("dynamic testing"); requirements documents, specifications, designs, and other project artefacts may all be quality controlled by "static testing".
80% of quality failures (defects) derive from failures in QA and QC ("common causes").
QI analyses the defect information provided by QC, and identifies improvements in:
* QA activities to prevent recurrence of the defects; and
* QC activities to ensure their earlier detection or avoidance.
So, in practice, many companies will call their testing team the QA Group.
