How Lean Tools Unlock Reliability: A Practical Guide

Manufacturers worldwide are realizing that investing in reliability delivers extraordinary returns—often 10‑to‑1, 20‑to‑1, or even 50‑to‑1—unmatched in other areas.

However, the path to reliability is not paved with silver bullets. Achieving it demands sustained effort and strategic investment.

They discover that success hinges on expanding predictive maintenance, refining planning and scheduling, conducting comprehensive FMEA, and deepening root‑cause analysis—while simultaneously upskilling the workforce.

Reliability is a company‑wide responsibility. Operations, procurement, engineering, leadership, and maintenance must collaborate toward a shared objective.

So the real question becomes: How can you accomplish this extensive reliability work while still handling existing workloads? The answer follows.

The Truth About PMs

A quick scan of your maintenance backlog often reveals a backlog of work orders that will stretch across months.

In reality, most maintenance activities have drifted from their origins, lacking engineered efficiency. When equipment fails, the common reaction is to add a PM task—cleaning, lubrication, or inspection.

A subsequent failure triggers another PM addition.

Over time, these incremental PMs accumulate into a seemingly endless workload.

Full of Waste and Ripe for Lean

Lean thinking offers significant opportunities to enhance the speed, quality, and cost efficiency of preventive maintenance.

The key is to scrutinize PM tasks at the granular level, especially those that persist simply because \\"that's how we've always done it.\\" We should label such tasks as waste.

Waste, in this context, refers to any PM activity that fails to deliver customer‑visible value. It is the primary driver of unnecessary time, cost, and complexity.

Thus, the biggest challenge is identifying and rejecting these entrenched wasteful practices.

Accelerate Reliability with Lean Tools

Viewing your PM program through a lean lens often reveals surprising volumes of non‑value‑added work. Ask: Does this task enhance manufacturing capacity or output? If not, quantify its impact and eliminate it.

The payoff is freeing up time, money, and manpower that can be redirected to genuinely value‑adding reliability initiatives that were previously unattainable.

Target the 60 Percent

Across diverse facilities, my analysis shows that roughly 30% of PM activities add no value and should be eliminated. An additional 30% can be replaced by condition‑monitoring technologies and predictive maintenance.

Consequently, over half of PM effort can be halted or swapped for predictive strategies with no adverse effects.

The Reliability Payoff

PM programs consistently deliver returns exceeding 10:1. By applying lean principles, you can capture high‑yield opportunities that substantially amplify your reliability gains.

Best of all, it transforms reliability into a self‑funding program.
