I'd be interested to hear any of your views, positive and negative in relation to safety sampling.

By safety sampling I mean trained observers recording the number of safety defects seen while touring specified locations by a prescribed route. Typically tours last for 15 min and are conducted at weekly intervals.

The unweighted count of defects is used to portray trends in the safety situation.

Regards

Paul

Been around for years. usually works better if it measures success rather than/as well as failure.
Thus a falling result (97% down to 95%)matches the way other measures work.
Don't keep doing it if the performance doesn't improve.
