F2J Industry: OEE Case Study Manufacturing Results — +15% in 6 Months With TEEPTRAK

This OEE case study manufacturing story documents how F2J Industry — a mid-sized industrial manufacturer — achieved a 15-percentage-point OEE improvement in just six months using the TEEPTRAK platform. It is a concrete, replicable example of what happens when a factory replaces estimation-based production management with real-time, sensor-driven OEE measurement: hidden losses surface immediately, root causes become visible within weeks, and targeted improvements compound month after month until the performance gap closes.

F2J Industry faced the same challenge that confronts thousands of manufacturers across Europe: production teams knew output was below potential, but lacked the granular, real-time data needed to identify exactly where time, speed and quality were being lost — and why. Manual production reports captured shift totals, but the micro-stops, speed losses and quality deviations that silently erode OEE remained invisible. The result was a persistent gap between theoretical capacity and actual output that no amount of spreadsheet analysis could close.

The Starting Point: Why F2J Needed an OEE Case Study Manufacturing Approach

Before deploying TEEPTRAK, F2J Industry operated with a production reporting process typical of many manufacturing SMEs. Operators recorded production counts, major downtime events and reject quantities on paper forms at the end of each shift. A production coordinator compiled this data into weekly Excel reports. Monthly management reviews examined output trends at a high level.

This approach had three fundamental blind spots. First, micro-stops — brief interruptions of 30 seconds to 5 minutes that individually seem insignificant but collectively destroy 10-20% of available production time — were never captured. Operators did not record them because each one felt trivial; management never saw them because they never appeared in any report. Second, speed losses were invisible. When a machine ran at 85% of its rated speed, the reduced output blended into the shift total with no flag, no alert, no root cause trail. Third, quality losses were underestimated. Rejects counted at end-of-shift omitted rework, startup waste and borderline units — inflating the reported quality rate by an estimated 2-3 percentage points.

F2J management suspected the true OEE was significantly lower than the numbers in the monthly reports suggested. They needed a system that would measure reality — automatically, continuously and without relying on operator data entry.

TEEPTRAK Deployment: 48 Hours From Installation to Live Data

TEEPTRAK deployed on the F2J production floor in 48 hours with zero production interruption — a critical requirement for a facility running two shifts, five days per week with limited buffer stock.

Day 1: sensor installation and connectivity. TEEPTRAK IoT sensors were installed on the initial pilot line — a high-volume assembly and packaging line that F2J identified as both strategically important and representative of the broader production environment. Current sensors on motor feeds captured machine running/stopped status. Optical sensors at the line output counted units produced. The TEEPTRAK gateway connected to the existing PLC to capture cycle time data and reject signals from the inline quality check station. Total installation time: 4 hours. No wiring changes to the machine. No software installation on any factory system.

Day 2: configuration, calibration and go-live. The TEEPTRAK team configured the dashboard: defining production orders, mapping stop reason categories to F2J standard codes, setting theoretical cycle times for each product reference, and establishing the shift calendar. Operator training — a 30-minute session covering the shop-floor terminal interface — completed by midday. The system went live at the start of the afternoon shift, and within minutes, the first real-time OEE reading appeared on the production dashboard.

The number on screen was 52%. F2J management had estimated their OEE at approximately 65-70% based on manual reporting. The 13-18 point gap between perception and reality was the first — and arguably most valuable — insight the system delivered.

Month 1: The Discovery Phase — Where OEE Was Really Being Lost

The first four weeks of continuous, automated measurement revealed the true anatomy of F2J production losses with a precision that manual reporting had never achieved.

Availability losses (38% of total OEE gap). TEEPTRAK data showed that the pilot line experienced an average of 47 minutes of micro-stops per shift — brief interruptions caused by sensor misalignments, product jams at transfer points and label feed hesitations. None of these events had ever appeared in manual logs because each individual stop lasted less than 2 minutes. Planned downtime for changeovers averaged 28 minutes versus the 15-minute standard — a 87% overrun that operators had normalised as inevitable. Unplanned breakdowns, while less frequent than micro-stops, averaged 22 minutes per event due to delayed detection: without real-time alerts, a stopped machine could sit idle for 5-8 minutes before anyone noticed.

Performance losses (41% of total OEE gap). The line ran at an average of 88% of rated speed, with speed losses concentrated during the first 30 minutes after each changeover (warm-up period) and the last hour of each shift (operator fatigue). TEEPTRAK cycle time analysis revealed that 3 of the 12 product references consistently ran 15-20% below theoretical speed — a pattern that suggested the theoretical cycle times for these references had been set optimistically during initial line qualification and never corrected.

Quality losses (21% of total OEE gap). Automated reject counting showed a true quality rate of 96.1% versus the 98.5% reported manually — a 2.4-point gap driven primarily by startup rejects (first 50-80 units after each changeover) and micro-defects that operators had been classifying as acceptable.

Months 2-3: Targeted Actions Based on Real Data

With the loss structure clearly mapped, F2J launched a focused improvement programme targeting the highest-impact losses first. The approach was deliberately simple: fix the biggest problems with the smallest interventions, using TEEPTRAK data to measure the impact of each change in real time.

Micro-stop reduction programme. The TEEPTRAK Pareto analysis identified the top 5 micro-stop causes, which accounted for 72% of all micro-stop time. Three of the five required only mechanical adjustments — tightening a guide rail, replacing a worn sensor bracket and adjusting the tension on a label feed mechanism. Total investment: under $500 in parts and 3 hours of maintenance time. Impact: micro-stop time dropped from 47 minutes to 19 minutes per shift within two weeks — a 60% reduction that directly added 28 minutes of productive time per shift.

Changeover time reduction. TEEPTRAK data showed that changeover duration varied dramatically depending on which operator performed it and which product transition was involved. The fastest operator completed the standard changeover in 14 minutes; the slowest took 42 minutes for the same transition. By filming the fastest changeover, creating a standardised procedure and training all operators to the best-practice method, average changeover time dropped from 28 minutes to 17 minutes — saving 11 minutes per changeover, with an average of 3 changeovers per shift.

Speed loss correction. The 3 product references running below theoretical speed were re-qualified. In two cases, the theoretical cycle times were genuinely too aggressive and were adjusted to reflect the machines true capability — correcting the OEE calculation rather than inflating it with unrealistic targets. In the third case, a mechanical adjustment to the filling station increased actual speed to match the theoretical rate. Combined impact: average performance rate improved from 88% to 93%.

Quality improvement. Startup reject analysis through TEEPTRAK data revealed that 65% of startup waste occurred because operators began production before the line reached stable operating temperature. A simple protocol change — running 20 warm-up cycles before counting production — reduced startup rejects by 70%. The quality rate climbed from 96.1% to 97.8%.

Months 4-6: Sustaining Gains and Scaling Improvements

The second quarter focused on sustaining the improvements already achieved, extending measurement to additional lines, and using JEMBA AI to identify the next layer of optimisation opportunities.

Real-time alerting culture. F2J configured TEEPTRAK alerts to notify shift supervisors immediately when OEE dropped below threshold on any monitored line. This transformed the supervisory role from end-of-shift reporting to real-time production management. Supervisors reported that they now spent 70% less time compiling reports and 70% more time on the production floor addressing active issues — a shift that reinforced the improvement trajectory.

JEMBA AI root cause analysis. As three months of continuous data accumulated, JEMBA began identifying patterns invisible to human analysis. The AI engine correlated micro-stop frequency with specific raw material batches, revealing that one suppliers packaging film generated 3x more label feed jams than alternatives. It identified that Monday morning OEE was consistently 4 points below the weekly average — a pattern traced to weekend machine cool-down affecting calibration. It flagged a gradual 0.3% per week decline in quality rate on one line — caused by progressive bearing wear that would have triggered a breakdown within 3 weeks without intervention.

Multi-line rollout. Based on pilot line results, F2J expanded TEEPTRAK deployment to 4 additional production lines during months 4-5. Each line followed the same 48-hour deployment process. Initial OEE readings on the new lines ranged from 48% to 61% — all significantly below the manually reported estimates, confirming that the visibility gap identified on the pilot line was systemic across the factory.

The Results: +15 OEE Points in 6 Months

Six months after initial deployment, the F2J pilot line OEE had moved from 52% (first automated measurement) to 67% — a 15-percentage-point improvement. The breakdown of gains tells the story of where value was recovered.

Availability: improved from 78% to 88%. Micro-stop reduction contributed 6 points; changeover optimisation contributed 3 points; faster breakdown response (enabled by real-time alerts) contributed 1 point. Performance: improved from 88% to 93%. Speed loss correction on the 3 under-performing product references contributed 4 points; reduced warm-up time after changeovers contributed 1 point. Quality: improved from 96.1% to 97.8%. Startup reject reduction contributed 1.2 points; ongoing SPC-driven defect reduction contributed 0.5 points.

Critically, these gains were achieved with near-zero capital investment. The total cost beyond the TEEPTRAK platform itself was under $2,000 in replacement parts and consumables. The improvements came entirely from better visibility, better decisions and better execution — the three things that real-time OEE measurement enables and manual reporting cannot.

Lessons From This OEE Case Study for Manufacturing Leaders

The F2J experience illustrates several principles that apply to any manufacturing facility considering a real-time OEE initiative.

The first measurement is the most valuable. The single most impactful moment in the entire F2J deployment was the first accurate OEE reading — 52% versus the assumed 65-70%. That 13-18 point reality gap instantly reframed the improvement conversation from incremental optimisation to urgent waste elimination. Every manufacturer who deploys automated OEE measurement discovers a similar gap. TEEPTRAK customers report an average of +29 productivity points after deployment — evidence that the gap between perceived and actual performance is universal and large.

Micro-stops are the hidden majority. At F2J, micro-stops accounted for 38% of the total OEE gap despite never appearing in any manual report. This is consistent with data across the TEEPTRAK customer base of 450+ factories in 30+ countries: micro-stops are typically the single largest category of availability loss in discrete manufacturing, yet they are systematically invisible without automated measurement.

Quick wins build momentum. The F2J improvement programme deliberately started with the simplest, lowest-cost interventions — mechanical adjustments, standardised procedures, protocol changes. These quick wins generated visible results within weeks, building operator confidence in the system and management confidence in the approach. The more complex, data-intensive improvements (JEMBA AI analysis, supplier quality correlation) came later, when the foundation of trust in the data was already established.

Real-time data changes behaviour. When operators and supervisors see OEE in real time — updated every minute on a shop-floor screen — their behaviour changes fundamentally. Response to problems accelerates because problems are visible immediately. Process discipline improves because deviations are detected instantly. Continuous improvement becomes a daily habit rather than a monthly meeting topic. This behavioural shift is the mechanism through which OEE measurement translates into OEE improvement.

Scale follows proof. F2J started with one line. The pilot results — undeniable because they were measured automatically rather than reported manually — justified expansion to 4 additional lines. This pilot-then-scale approach is the deployment model TEEPTRAK recommends and the one that delivers the fastest, most sustainable results.

Frequently Asked Questions

What OEE improvement can manufacturers expect from TEEPTRAK?

Results vary by starting point and facility, but TEEPTRAK customers report an average of +29 productivity points after deployment. F2J Industry achieved +15 OEE points in 6 months. The initial visibility into previously hidden losses — micro-stops, speed deviations and quality gaps — typically reveals 10-20 points of improvement potential.

How long does TEEPTRAK take to deploy on a production line?

Standard deployment completes in 48 hours: Day 1 for sensor installation and gateway connectivity, Day 2 for dashboard configuration, operator training and go-live. No production stop is required. F2J went from zero installation to live OEE data in under 48 hours.

Does TEEPTRAK require changes to existing machines or control systems?

No. TEEPTRAK uses non-invasive IoT sensors (current clamps, optical counters, vibration sensors) that install on the outside of machines without any modification to electrical panels, PLCs or machine software. The system reads data in parallel with existing controls.

What are the most common sources of hidden OEE loss?

Micro-stops (brief interruptions under 5 minutes) are consistently the largest hidden loss category, typically accounting for 30-40% of the total OEE gap. Speed losses from machines running below rated speed and under-reported quality defects are the next most significant categories.

How does JEMBA AI help improve OEE?

JEMBA is the TEEPTRAK artificial intelligence engine that analyses production data to identify root causes of OEE losses. While TEEPTRAK tells you that OEE dropped, JEMBA tells you why — correlating patterns across machine settings, material batches, shift schedules and environmental conditions to surface insights that human analysis would take days or weeks to find.

What is a realistic timeline for OEE improvement after deploying real-time monitoring?

Most TEEPTRAK deployments see measurable improvement within the first month as the visibility into micro-stops and speed losses enables immediate quick wins. Significant improvement (10+ OEE points) typically occurs within 3-6 months as targeted action programmes address the root causes identified by continuous monitoring and AI analysis.

Can TEEPTRAK measure OEE across multiple production lines and sites?

Yes. TEEPTRAK is deployed in 450+ factories across 30+ countries. The platform supports multi-line, multi-site deployment with centralised dashboards that enable performance benchmarking across lines, shifts, products and facilities. F2J expanded from 1 pilot line to 5 lines within 6 months based on initial results.
