When a mid-sized dairy processing facility in Wisconsin discovered their pasteurization equipment was consuming 30% more energy than design specifications and experiencing unplanned downtime every 11 days on average, their maintenance costs had ballooned to $840,000 annually—nearly double the industry benchmark. The plant processed 180,000 gallons of milk daily across multiple product lines, but their reactive maintenance approach meant critical equipment failures routinely halted production, created quality inconsistencies, and drove up both labor and parts expenditures. Within 18 months of implementing a structured preventive maintenance program with digital tracking, they reduced maintenance costs by 42%, eliminated 89% of unplanned downtime, and extended equipment lifespan by an average of 3.2 years. Sign up for Oxmaint to discover how your dairy facility can achieve similar cost reductions through optimized maintenance planning.
Case Study: Valley Fresh Dairy
How Preventive Maintenance Cut Costs by $350K Annually
The Challenge: Escalating Costs and Unreliable Assets
Valley Fresh Dairy operated a 24/7 processing facility with aging equipment, inconsistent maintenance practices, and no centralized system for tracking asset performance. Their challenges mirrored those faced by many mid-sized dairy processors transitioning from reactive firefighting to strategic asset management.

Root Cause Analysis Revealed Four Critical Issues
01
No Preventive Maintenance Schedule
Equipment was serviced only after failure. Critical components like pump seals, heat exchanger gaskets, and conveyor bearings were run to failure rather than replaced on a preventive schedule. This created cascading failures where one component breakdown damaged adjacent equipment.
02
Paper-Based Maintenance Logs
Technicians recorded work on clipboards and filed reports in binders. When auditors requested maintenance histories or when supervisors needed to analyze failure patterns, it took days to locate and compile records. Many intervention details were never documented at all.
03
Lack of Asset Performance Visibility
Management had no real-time data on equipment health, maintenance costs per asset, or trending failure modes. Decisions about capital replacement versus repair were made on gut feel rather than data-driven analysis of lifecycle costs.
04
Reactive Parts Inventory Management
Critical spare parts were ordered only after equipment failure, extending downtime by 2-4 days while waiting for overnight shipping. Conversely, slow-moving parts cluttered shelves, tying up working capital in obsolete inventory.
The Solution: Structured Preventive Maintenance Program
Valley Fresh partnered with maintenance consultants to design and implement a comprehensive preventive maintenance program supported by a digital CMMS platform. The 18-month implementation focused on three phases: asset inventory and criticality assessment, preventive maintenance schedule creation, and digital system deployment with staff training.

Trained 23 maintenance technicians on digital checklist completion and photo documentation
Configured automated alerts for overdue tasks, critical asset failures, and parts reorder points
Established monthly analytics reviews tracking cost per asset, labor efficiency, and downtime trends
Key Success Factors and Implementation Insights
Executive Sponsorship and Budget Commitment
Plant management allocated $180K for CMMS implementation and dedicated two full-time staff members to the project. This visible commitment signaled to the maintenance team that the initiative was strategic, not optional.
Phased Rollout with Quick Wins
Rather than attempting facility-wide implementation simultaneously, the team started with three critical assets: HTST pasteurizers, CIP systems, and main refrigeration compressors. Early success with these high-visibility assets built momentum and organizational buy-in.
Technician Involvement in PM Task Design
Maintenance technicians who actually serviced equipment helped write PM checklists and set realistic service intervals. This created ownership and ensured procedures matched real-world conditions rather than theoretical OEM recommendations.
Data-Driven Continuous Improvement
Monthly reviews of CMMS analytics identified which PM tasks were preventing failures versus which were unnecessary. Over 12 months, the team eliminated 340 low-value PM tasks and added 180 high-value tasks based on failure data, optimizing labor allocation.

Technology Platform: What Made It Possible
Valley Fresh selected a cloud-based CMMS platform that integrated with their existing ERP system and provided mobile access for technicians. The key capabilities that drove results included automated work order generation, mobile checklist completion with photo attachments, parts inventory integration, and real-time cost analytics by asset and department.
Automated PM Scheduling
System generates work orders automatically based on calendar intervals, runtime meters, or production cycles. Technicians receive mobile notifications three days before tasks are due, with all required checklists and parts lists attached.
Mobile Work Order Completion
Technicians complete digital checklists on tablets at the equipment location, attach photos of component condition, record sensor readings, and note any issues discovered. All data syncs in real-time to the central database.
Parts Inventory Integration
When PM tasks consume parts, inventory quantities automatically update. Reorder point alerts notify purchasing when critical spares drop below minimums, preventing stockouts without overstocking slow-moving items.
Cost Analytics Dashboard
Real-time visibility into maintenance costs by asset, production line, and failure mode. Managers identify high-cost equipment requiring capital replacement versus repair, and track labor efficiency trends across the team.
Compliance Documentation
Every maintenance intervention timestamped and logged with technician ID, parts used, and completion photos. Pulls audit-ready reports for SQF certification, FDA inspections, and insurance compliance in under 60 seconds.
Predictive Analytics
System analyzes failure patterns and identifies assets trending toward breakdown based on increasing repair frequency or rising labor hours. Flags candidates for proactive intervention before catastrophic failure occurs.

The transformation was remarkable. We went from firefighting daily equipment failures to having full visibility and control over our maintenance operations. Our technicians are more productive because they're doing planned work instead of emergency repairs. Our production team has predictable uptime. And our CFO is thrilled with a 42% reduction in maintenance costs. The CMMS paid for itself in seven months and will save us over $350,000 every year going forward.
Lessons Learned and Recommendations
Start with Criticality Assessment
Not all assets deserve equal PM attention. Focus initial efforts on equipment where failure impacts production, safety, quality, or compliance. Valley Fresh achieved 60% of their downtime reduction by addressing just 15% of their asset base—the critical few.
Invest in Technician Training
Mobile CMMS adoption depends on technician buy-in. Valley Fresh provided hands-on training, addressed concerns about "big brother" tracking, and showed how digital checklists made their jobs easier by eliminating duplicate data entry and paper logs.
Clean Up Master Data Before Go-Live
Garbage in, garbage out. Valley Fresh spent three months verifying equipment locations, nameplates, and specifications before importing data into the CMMS. This painful upfront work prevented cascading errors and ensured PM tasks went to the right assets.
Track Leading Indicators, Not Just Lagging
Downtime and cost are lagging indicators—problems already happened. Valley Fresh tracks PM compliance percentage and mean time between failures as leading indicators that predict future performance before issues surface.
Plan for Data-Driven Iteration
Initial PM schedules won't be perfect. Valley Fresh built in quarterly reviews to analyze failure data, adjust PM frequencies, and eliminate tasks that weren't preventing failures. Continuous improvement is essential for sustained results.
Link Maintenance to Business Outcomes
Frame the program in business language—uptime, cost reduction, quality consistency—not maintenance jargon. Valley Fresh's leadership support came from showing how PM directly impacted production capacity and profit margins.
