Without any available cohort studies to test exposure over a long period of time, though, they have had to rely on lab studies, which failed to find any clear or reproducible biological effects.

In addition, snapshots of system utilization and LTP test output files were taken daily or weekly to have data points to determine whether systems were degrading during long-period runs.

Even if your team does reserve a long or late period for system test, it is important in a Value Stream Map to distinguish between the time spent doing actual testing and the time fixing code.
