Manufacturing Electric Vehicles in Europe: Challenges & Possible Solutions
The European electric vehicle market stands in a critical position. With the EU’s ambitious target to phase out ICE vehicles by 2035, EV manufacturers face
In sectors like automotive, aerospace, and electronics, even a tiny defect can lead to costly recalls, compliance issues, or loss of customer trust. Maintaining high-quality standards while managing operational efficiency is no easy feat. This is why many engineering and manufacturing companies are turning to Six Sigma, a data-driven approach that ensures consistency, reduces variability, and boosts overall productivity.
In this article, we’ll break down what Six Sigma is, how it applies to engineering and manufacturing, and how OEMs and contract manufacturers alike can use it to drive performance, reduce cost, and deliver better results.
In the context of contract manufacturing, implementing lean manufacturing principles and Six Sigma in the manufacturing industry ensures that outsourced production meets high standards of quality and efficiency.
Contract manufacturers benefit from these methodologies by minimizing errors, shortening production cycles, and reducing costs, key factors that influence client satisfaction and profitability.
Adopting Six Sigma lean manufacturing processes helps both OEMs and their manufacturing partners maintain better control over quality, improve transparency in operations, and build long-term, performance-based relationships.
Six Sigma is a quality improvement methodology that focuses on reducing defects and minimizing variation in manufacturing processes. It aims to enhance performance by identifying the root causes of errors and eliminating inefficiencies at their source.
The name “Six Sigma” comes from statistics, where a “sigma” (σ) denotes standard deviation, a measure of variation.
Originally developed by Motorola in the 1980s, Six Sigma gained global traction when General Electric used it to save billions by applying it across their manufacturing and business operations.
Whether you’re an OEM or working with a contract manufacturer, maintaining strict control over product quality and operational performance is essential. By adopting Six Sigma principles, manufacturers can:
When combined with Lean Manufacturing, which focuses on eliminating waste and optimizing processes, Six Sigma becomes even more effective. This integrated approach, known as Lean Six Sigma, leverages data-driven analysis to reduce process variation while streamlining workflows.
The result is a powerful framework that improves product consistency, enhances speed, and helps manufacturers respond more effectively to market demands in a highly competitive industrial landscape.

At the core of Six Sigma is the DMAIC methodology, a five-step process used to drive continuous improvement:
Tools: Project Charter, SIPOC Diagram, VOC Analysis
Tools: Process Mapping, Gage R&R, Control Charts
Tools: Fishbone Diagram, 5 Whys, Pareto Analysis, Regression Analysis
Tools: Design of Experiments (DOE), Failure Modes and Effects Analysis (FMEA), Pilot Testing
Tools: Control Plans, Process Audits, Statistical Process Control (SPC)
Here are some of the most widely used Six Sigma tools and how they help:
| Tool | Purpose |
|---|---|
| Pareto Chart | Identify major causes of defects |
| Ishikawa (Fishbone) Diagram | Root cause analysis |
| Histogram | Visualize data spread |
| FMEA | Predict and prevent potential failures |
| DOE | Optimize inputs to get best outputs |
| Process Capability Analysis | Determine if a process meets specifications |
Six Sigma is used in industries like:
Benefits of Implementing Six Sigma
Manufacturers who implement Six Sigma can expect:
Like any operational change, Six Sigma comes with its challenges:
Whether you’re optimizing a CNC machining process or reducing defects in circuit board assembly, Six Sigma gives you a clear, structured path toward operational excellence. When applied correctly, it leads to real, measurable results: better quality, faster turnaround, and happier customers.
In the context of contract manufacturing, adopting Six Sigma principles ensures your outsourcing partners meet high standards of quality and delivery, making it a strategic asset for OEMs.
