The Illusion of Perfect KPIs: Why Are We Still Having LOPCs?

By Jeff Goldstein, P.E., Principal Engineer, Bighorn Integrity

Many refineries report zero overdue inspections month after month and still experience Tier 1 and Tier 2 loss of primary containment (LOPC) events. This Inspectioneering Journal article argues that the gap is often not the metrics themselves but the failure to translate them into daily action by inspectors, and shows how the Objectives and Key Results (OKR) framework used by Google's site reliability teams can connect individual inspector work to the goal of preventing LOPCs.

Key takeaways

  • Clean compliance KPIs such as “zero overdue inspections” can coexist with LOPCs. Either the KPIs are vanity metrics, or their goals never reach the individual contributors doing the work.
  • OKRs pair a directional objective with three to five measurable key results, reviewed monthly or quarterly, visible to the whole team, and decoupled from compensation.
  • Good mechanical integrity key results sit inside the inspector's sphere of influence: inspection effectiveness, root-cause analysis of below-T-min findings, and closure of critical inspection work requests.
  • Tying CML reduction targets to bonuses invites people to deactivate critical CMLs to hit the number. Keep OKRs separate from pay.

Why do facilities with perfect KPIs still have LOPCs?

The article identifies two causes. First, KPIs can be poorly crafted “vanity” metrics that unintentionally report good news up the chain of command. Second, and the focus of the article, the goals behind well-designed KPIs are not translated into action by inspectors and other individual contributors. Inspectors carry more tasks than they can complete without triage, managers cannot oversee every activity, and software cannot replace experienced judgment. The success of an integrity program therefore has to be owned at the front line.

What can refinery inspection teams learn from Google?

Google achieves reliability at scale through site reliability engineering (SRE), which builds reliability into systems instead of depending on manual intervention, and through OKRs, the goal-setting protocol John Doerr introduced to Google in 1999. A top-tier integrity department works the same way: work processes and data analysis designed to detect corrosion threats before they become operational problems, with every person's daily work tied to that objective.

An example OKR for a unit inspector

Objective: Proactively identify and mitigate corrosion in the Crude Unit before a loss of primary containment occurs.

Key resultWhat it measures and why
Achieve an Inspection Effectiveness KPI of 90%The ratio of integrity threats found before they leak or require unplanned work (for example, 2 to 10 years of remaining life) to all threats found. As a ratio, it works for mature, low-corrosion units and for units with chronic corrosion alike.
Initiate root-cause analysis on at least three below-T-min findingsTurns a lagging indicator into a leading one and makes corrosion visible to the disciplines that can mitigate it.
100% action plan coverage for critical inspection work requestsSeparates integrity-critical IWRs from cosmetic maintenance so they don't get lost in the maintenance backlog.

Risk-weighted overdue rate

Instead of a raw “zero overdue” target, reduce the risk-weighted overdue CML count by 50%. Weighting CMLs on high-risk circuits (by RBI results or API 570 piping class) above low-risk services steers inspectors to the CMLs that matter first. The weighting scheme must be designed carefully to avoid gaming.

End-of-life CMLs without action

Review and disposition every CML that is below T-min or within three years of its calculated retirement date. This targets a largely preventable class of LOPC: failures where the thickness data already showed the problem but no action was taken in time.

Inspection strategies optimized for damage mechanisms

Pilot an optimization of inspection coverage on at least 25% of piping circuits in a unit, confirming that each CML and NDE method fits the expected damage mechanisms. This reduces risk and removes inspections that add no value.

How to implement OKRs in a mechanical integrity program

  • Keep them transparent and collaborative. Share OKRs across the department so peers can coordinate, and aim for more than half of key results to be written by front-line staff.
  • Make them aggressive. Easy goals breed check-the-box reporting. Stretch goals expose when resources are being pulled to competing priorities.
  • Divorce them from compensation. This encourages honest reporting and lets priorities change during the year.
  • Review them monthly. Annual reviews become autopsies. Monthly reviews allow quick triage, reallocation of resources, and recognition of wins.
