Lean 6 Sigma Training Course - Quantitative Analysis in Lean Six Sigma Process Improvement, Manufacturing Process Management, Cost Reduction, and Process Improvement at SINOWIN INDUSTRY (VIETNAM) CO., LTD.

Quantitative Analysis in Lean Six Sigma Process Improvement

VINTECOM International has successfully completed the advanced training program “Lean Production & Lean Six Sigma for Manufacturing Cost Reduction” for the engineering management, production management, and process improvement teams at SINOWIN INDUSTRY (VIETNAM) CO., LTD. — a company specializing in the manufacturing of electromagnetic products and magnetic components for the automotive and related industries.

In the manufacturing environment of high-precision magnetic components for automotive applications, technical requirements extend far beyond dimensional accuracy and product appearance. They are directly associated with magnetic stability, coating uniformity, corrosion resistance capability, assembly precision, and overall process consistency in accordance with Automotive supply chain requirements. As a result, controlling process variation becomes a critical factor in manufacturing operations.

The training program was developed by VINTECOM International based on practical Lean Six Sigma methodologies at the Yellow Belt, Green Belt, and Black Belt levels, focusing on the capability to identify hidden losses within manufacturing systems and transform production data into measurable improvement actions through financial KPIs and process performance indicators.

During the training program, participants were introduced to Lean Production thinking with a focus on eliminating Non-Value Added Activities (NVA) in order to minimize common manufacturing wastes such as:

Overproduction
Waiting
Transportation
Overprocessing
Inventory
Motion
Defect

However, the program content did not stop at conventional Lean Manufacturing concepts, but was further expanded toward Cost of Poor Quality (COPQ) and Hidden Factory analysis — referring to operational losses that are not easily visible yet directly impact the profitability of the organization.

For the automotive electromagnetic and magnetic component manufacturing industry, these losses commonly appear in forms such as:

Magnetic performance variation between production lots
Coating/plating thickness variation
Tolerance deviation after CNC precision machining
Scrap caused by micro-cracks during sintering or machining processes
Rework resulting from plating defects or adhesion failures
Downtime associated with tooling, jig fixtures, or instability of process parameters

From a Six Sigma perspective, these are not merely “product defects,” but indicators of uncontrolled variation within the manufacturing process system.

Therefore, the training program strongly focused on statistical analysis capability and process stability control through:

SPC (Statistical Process Control)
Process Capability Analysis
Cp / Cpk
Common Cause vs. Special Cause Variation
Control Chart Interpretation
Process Stability Assessment

Participants were not only trained on how to “read SPC charts,” but were also guided on how to interpret the Voice of the Process in comparison with the Voice of the Customer, thereby understanding why a process may still produce conforming products while not yet being considered a capable process under Automotive Quality Management System requirements.

Another key focus of the training program was Root Cause Analysis (RCA) based on the Lean Six Sigma Black Belt methodology.

Tools such as:

5 Why
Fishbone Diagram
Pareto Analysis
Is / Is Not Matrix
FMEA Risk Analysis

were implemented through practical case studies related to:

CNC precision machining
Magnet coating/plating
Dimensional variation
Surface defects
Process instability

In particular, participants were guided on how to transform “failure symptoms” into “process failure modes,” enabling improvement actions that emphasize prevention rather than short-term corrective actions.

The training program also emphasized the role of the Process Owner in sustaining improvement effectiveness after DMAIC project implementation. This is especially critical within Automotive manufacturing environments, where many improvement initiatives fail not because of insufficient technical solutions, but because organizations fail to sustain the Control Phase after improvement activities.

Topics such as:

Control Plan
Reaction Plan
Layered Process Audit
Visual Management
Daily Management
KPI Deployment

were integrated into the program to help organizations establish sustainable improvement mechanisms rather than short-term improvement activities.

Through this training program, VINTECOM International continues to demonstrate its capability in implementing highly practical Lean Six Sigma programs for FDI enterprises and high-technology industrial supply chains in Vietnam, particularly in industries such as:

Automotive
Electronics
Precision Machining
Magnet Manufacturing
Surface Treatment & Plating

With a training approach closely aligned with real manufacturing operations, the program focuses not only on “tool knowledge,” but also on building data-driven improvement capability and sustainable operational optimization.
