MRO Inventory Optimization Case Study for Cement Plants

Spare parts budgets in cement plants tend to grow the same way every year, a bit more stock added after every stockout, and nothing ever pulled back out. Bearings, liners, and gearbox parts pile up in the store because nobody wants to be the one who ran out during a kiln stop, while other parts that were ordered years ago for a machine that no longer exists sit untouched on the same shelf. CMMS-driven inventory control fixes this by tying every part to real usage and real work orders instead of guesswork. Sign up to see what your own store room would look like once it's tracked properly.

-27% Inventory Cost
Typical reduction in carrying cost after removing excess and obsolete stock
Near-Zero Stockouts
Critical spares tracked against real PM and breakdown demand, not guesswork
Full Parts Traceability
Every part linked to the asset, work order, and technician who used it
The Use Case

The store room was running on a spreadsheet nobody trusted. Purchasing kept reordering parts that were already sitting on a back shelf, technicians walked to the store not knowing if a bearing was actually in stock, and nobody could say which parts hadn't moved in three years versus which ones were about to run out before the next kiln shutdown.

Where Spare Parts Budgets Were Being Wasted

Inventory Issue Root Cause CMMS Fix Applied
Excess Stock Reordering based on habit instead of actual consumption Reorder points set from tracked usage history per part
Critical Stockouts No link between PM schedules and required spare parts Parts reserved automatically against upcoming PM tasks
Manual Tracking Store ledger updated by hand, often days behind actual usage Stock levels updated automatically as parts are issued
Obsolete Parts Parts bought for retired equipment never flagged or cleared Dead stock identified from zero movement against active assets

Inventory Position Before And After CMMS

Before

Reorder decisions made from memory and spreadsheet guesswork

Stock counts updated by hand, often out of date within days

No visibility into which parts were tied to which asset

After

Reorder points calculated from tracked consumption per part

Stock levels updated automatically the moment parts are issued

Every part traceable to the asset, work order, and technician

The Outcome

Inventory cost dropped by 27% without a single critical part running out. The store room didn't need more shelf space or a bigger budget, it needed a system that could tell the difference between a part that was genuinely needed and one that was just carried forward out of habit.

Why Inventory Visibility Cuts Cost Without Cutting Stock

Reducing spare parts cost doesn't mean carrying less of what you actually need, it means stopping the slow buildup of parts nobody is tracking against real demand. When every part is linked to the asset it belongs to and the work order it was used on, the store room stops growing by default and starts reflecting what the plant actually consumes.

Frequently Asked Questions

Q How does CMMS reduce MRO inventory costs without risking stockouts?
Reorder points are calculated from actual part consumption and linked PM schedules, so stock is trimmed where usage doesn't justify it while critical spares stay reserved for upcoming maintenance.
Q How does a CMMS identify obsolete or dead spare parts?
Parts that show zero movement against any active asset over time get flagged automatically, making it easy to spot stock that was bought for equipment no longer in service.
Q Does inventory optimization require a full warehouse recount to start?
Not necessarily, most plants start by tagging parts to assets and work orders as they're used, letting accurate stock data build up from real activity rather than a one-time count.
