When it comes to continuous improvement, few metrics tell a clearer story than **Overall Equipment Effectiveness (OEE)**. OEE gives manufacturers an at-a-glance understanding of how effectively their equipment is being utilized — combining **availability, performance, and quality** into one powerful KPI.
But data alone doesn’t drive improvement. It’s what you *do* with the data that counts.
In this post, we’ll show how to use **OEE data collected in Scytec DataXchange** and analyze it in **Minitab Statistical Software** to uncover bottlenecks, identify root causes, and deliver measurable gains on the shop floor.
## **Use DataXchange to Collect Accurate OEE Data**
Using Scytec DataXchange, machine utilization and OEE data are collected automatically and continuously. For example, suppose we pull weekly OEE data from a CNC machining cell:
| **Week** | **Availability (%)** | **Performance (%)** | **Quality (%)** | **OEE (%)** |
| --- | --- | --- | --- | --- |
| 1 | 88.0 | 92.5 | 99.1 | 80.5 |
| 2 | 86.2 | 91.8 | 98.9 | 78.0 |
| 3 | 89.7 | 93.2 | 99.0 | 82.6 |
| 4 | 85.5 | 91.4 | 98.7 | 77.2 |
| 5 | 84.9 | 92.0 | 99.0 | 77.4 |
This data set shows a stable process, but OEE is hovering around 78–82% — below the world-class benchmark of 85%. The question: *What’s limiting throughput?*
## **Analyze the Data Using the Minitab Solution Center**
Seamlessly export your DataXchange data into the [Minitab Solution Center](https://www.minitab.com/en-us/products/minitab-solution-center/).
Start with a **Time Series Plot** in Minitab to see how OEE trends over time.
- Go to: *Graph → Time Series Plot → Simple*
- Select OEE as the variable, and Week as the time scale
The chart reveals that OEE dips significantly in weeks 2, 4, and 5. The variation seems to follow a pattern — perhaps tied to shift schedules or setup cycles.
Next, create an **Individuals Control Chart (I-Chart)** to monitor variation and stability.
- Go to: *Stat → Control Charts → Individuals → I-MR Chart*
- Select OEE as your variable
If the chart shows points below the lower control limit, it signals **special cause variation** — a clue that certain events (like tool changes or operator swaps) are affecting performance.
## **Measure Strength of Relationship**
To see which component of OEE is causing the shortfall, use **correlation **in Minitab.
- Go to: *Stat → Basic Statistics → Correlation*
- Select OEE and the three components: Availability, Performance, and Quality
Minitab will produce a **correlation matrix** showing how strongly each factor relates to OEE. Here’s an example based on our sample DataXchange dataset:
| **Variable** | **Correlation with OEE** | **Interpretation** |
| --- | --- | --- |
| Availability | 0.92 | Very strong relationship — as Availability improves, OEE rises significantly |
| Performance | 0.65 | Moderate relationship — affects OEE, but less strongly |
| Quality | 0.18 | Weak relationship — minimal influence on overall OEE |
This analysis tells us that **availability** is the primary driver of OEE variation.
In practical terms, your machines are producing good parts efficiently — but they’re **not running often enough**. That points to opportunities in **reducing unplanned downtime, improving scheduling, or optimizing setup times** before investing in new equipment.
## **Brainstorm Improvements**
Use Minitab’s **Fishbone Diagram (Cause & Effect Diagram)** or **FMEA** (available in [**Minitab Workspace**](https://www.minitab.com/en-us/products/workspace/)) to brainstorm potential downtime drivers:
- Set-up and changeover delays
- Material shortages
- Operator availability
- Preventive maintenance frequency
By pairing real downtime codes from DataXchange with brainstorming in Minitab Workspace, your team can prioritize the top causes systematically.
## **Test, Validate and Monitor the Fix**
Once you’ve implemented improvements (say, reducing setup time by 15%), use Minitab to verify results statistically.
Run a **2-Sample t-Test** comparing OEE before and after the change:
| **Period** | **Mean OEE (%)** | **Std Dev** |
| --- | --- | --- |
| Before | 78.0 | 2.4 |
| After | 83.5 | 1.8 |
P-value = 0.004 → statistically significant improvement ✅
Your analysis confirms that the process change produced a real, measurable gain.
Utilize DataXchange to continuously monitor current utilization of machines and OEE data, harness the power of [Minitab Connect](https://www.minitab.com/en-us/products/connect/)to get live control charts of OEE to monitor changes and identify potential changes before they occur.
## **The Power of Data + Analysis**
By combining **DataXchange’s real-time visibility** with **Minitab’s analytical precision**, manufacturers can move beyond “what happened?” to “why did it happen?” — and ultimately, “how do we make it better?”
With this approach:
- DataXchange captures *the truth* of what’s happening on your machines.
- Minitab uncovers *why* it’s happening and what to fix first.
- Together, they deliver sustainable throughput gains and a stronger continuous improvement culture.
