Apparently staff on TSA checkpoints are on performance related pay.
"Good afternoon, Chairman Akaka, Ranking Member Voinovich, and distinguished members of the Subcommittee. I am pleased to be here today to discuss TSA's progress on our pay-for-performance system, known as PASS [Performance Accountability and Standards System]...
How does PASS improve security? When you get paid more to do a better job, you do a better job. PASS is targeted to reward excellent performance. That is an incentive to perform at the highest level to which you are capable. PASS rewards the individual performance necessary to achieve TSA's organizational goals and that increases security.
TSA's pay-for-performance system is driven by validated data. Its performance metrics are standardized, measurable, observable and almost completely objective."
The administrators don't realise that what gets measured in these simplistic target systems is what is easy to measure not what is important. So the focus is on the wrong things and real security is compromised.
