The 'Number of IT employees attending security training sessions' is an activity metric, indicating participation but not necessarily a change in practical behavior or actual security posture.

This outcome-based metric directly demonstrates behavioral change and its impact on security posture.

The 'Number of reported security incidents' is a lagging indicator for broader security posture and may not specifically isolate the progress in IT employee behavior related to application design and configuration.

The 'Results of application security awareness training quizzes' measure knowledge retention, not necessarily the consistent application of that knowledge in practical behavior during application design and configuration.
