Leading  metrics  are  intended  for  local  use  to  address  local  issues  and  are  not  typically
               appropriate for long term trending or corporate/external reporting.





                    A company created a metric to measure
                    safety   instrumented     system    (SIS)
                    activations/failures. They found that the       A  company  created  a  metric  to
                    metric spiked when a new project was            address  pressure  safety  valve  (PSV)
                                                                    test  failures.  Through  using  this
                    being implemented. Having focused on            metric,  they  found  issues  with  the
                    the SIS metric and driving it down to the       inspection, testing and maintenance
                    target, they moved on to the next topic.
                    This  next  topic  was  process  safety         program.  They  also  saw  the  metric
                    issues  in  new  project  implementation.       spike  when  a  new  Inspection,
                                                                    Testing,  Maintenance  (ITM)  vendor
                    Through  this  they  found  issues  with        was contracted. Both of these areas
                    time  available  to  complete  a  task,         were  the  topic  of  subsequent
                    setting adjustments, and design issues
                    –  all  topics  that  could  be  addressed      process safety metrics.

                  The use of Loss of Containment (LOC) Reporting as a leading indicator was so successful
                  at one facility that leadership established it as a corporate leading metric. Several sites
                  used this approach to great effect, increasing both the awareness of spills and leaks as
                  well as improving the timely repair or prevention of leaks. After more than a year of using
                  this metric, reporting started to taper off, perhaps partly due to reduction in LOC events,
                  partly due to attention being shifted to ‘the next problem’. As a result, LOC reporting
                  numbers began to decline. When the metric was shared at a leadership team meeting,
                  the leaders celebrated that LOC events were trending downward, having forgotten (or
                  not understood) that the purpose of the metric was to encourage more reporting so that
                  LOCs could be repaired.
