About Sigma Lean

Led by James Derby, Sigma Lean brings over 20 years of hands-on facility maintenance and operational leadership to plants across the nation. Based in Naples, Florida, we partner with facility leaders to eliminate downtime, restructure CMMS systems, and deliver measurable cost savings.

Two decades of boots-on-the-ground experience

With more than 20 years managing light commercial and heavy industrial maintenance departments, we know firsthand what works and what fails on the plant floor. Our passion is helping facility teams overcome chronic bottlenecks and build reliable, efficient maintenance operations. From on-site evaluations to remote guidance and practical staff training, we deliver real solutions tailored to your workflow.

Turnaround results through critical component control

When unexpected machine breakdowns drain your budget, the root cause is often missing critical spares and unorganized stores. We put boots to the ground to audit failure histories, categorize high-risk equipment, and design intelligent inventory strategies. By pairing Vendor-Managed Inventory (VMI) solutions with automated CMMS reordering, we ensure essential components are always on the shelf right when your technicians need them.

Integrity first with performance pricing

Integrity is our foundational standard because there is no price you can put on honesty. We believe in our ability to streamline your maintenance spending so strongly that we start with a fee-free initial assessment and work on a simple guarantee: we do not get paid until your business is on track to save money. If we cannot generate genuine savings and reliability for your plant, you owe us nothing.

"Sigma Lean rolled up their sleeves and reorganized our entire parts room and CMMS within weeks. Having our critical components stocked and automated cut our emergency downtime significantly."
