Leading vs. Lagging Indicators: Why You Can't Drive Looking in the Rearview Mirror (2026)

Imagine you are driving down a highway at 100 km/h.
To stay safe, you look through the Windshield. You watch the curve ahead. You check your speed.
Now, imagine if you covered the windshield and tried to drive by looking only in the Rearview Mirror.

You would see the road markers flashing by after you passed them. You would know exactly where you were 5 seconds ago.
But when the car in front of you brakes, you wouldn't know until you hit it.

This sounds crazy, but it is exactly how most factories run their maintenance departments.
They focus entirely on Lagging Indicators (The Rearview Mirror).

• "We had 10 breakdowns last month." (Too late).

• "We spent $50,000 on repairs." (Too late).

To stop crashing, you need to uncover the windshield. You need to focus on Leading Indicators.

1. What is a Lagging Indicator? (The Score)

A Lagging Indicator is an Output. It measures the result of your work.
It is important for keeping score, but it is useless for preventing problems today.

Common Lagging Indicators:

• MTTR (Mean Time To Repair): How long it took to fix the broken machine.

• Total Downtime: How many hours you lost.

• Maintenance Cost: How much you spent.

If you run your morning meeting discussing only these numbers, you are doing an "Autopsy." You are discussing a dead body. You cannot bring it back to life.

2. What is a Leading Indicator? (The Warning)

A Leading Indicator is an Input. It measures the activities that prevent failure.
If these numbers look bad, you know a crash is coming, and you have time to swerve.

Common Leading Indicators:

• PM Compliance: Did we finish all the preventive tasks this week?

  • Insight: If Compliance drops to 60%, you will have a breakdown next week.

• Backlog Size: Is the list of pending repairs growing?

  • Insight: If the backlog grows by 10%, your team is drowning.

• Observation Alerts: How many "Small Issues" (leaks, noises) were reported by operators?

  • Insight: High reporting means high awareness. Low reporting means people are ignoring problems (danger).

3. Shifting Your Focus

You cannot drive a car by looking at the speedometer (Leading) and the mirror (Lagging) at the same time. You have to choose where to put your attention.

The Strategy:
Spend 20% of your time on Lagging (Reporting to the Boss).
Spend 80% of your time on Leading (Managing the Team).

• Don't ask: "Why did it break?" (Rearview).

• Ask: "Are we up to date on our inspections?" (Windshield).

4. How Software Clears the View

Why do managers rely on Lagging Indicators? Because they are easy to get from accounting.
Leading Indicators are hard to track manually. You can't know "PM Compliance" in real-time if your checklists are on paper.

Fabrico acts as your Dashboard.

• Real-Time Dials: It shows you the "PM Completion %" live.

• Trend Lines: It shows if the backlog is spiking.

• Alerts: It warns you: "Compliance dropped below 80%. Risk of failure increasing."

Conclusion: Look Forward

The past is unchangeable. The future is preventable.
Stop managing your factory based on what happened last month. Start managing based on what is happening right now.
