Lean Management

KML has established a full-staff improvement mechanism to transform lean practices from a management requirement into a daily habit:

• Proposals from frontline employees: Encourage frontline positions such as production and quality control to propose small improvements, such as optimizing the operating method of a certain process or adjusting the placement of materials, and provide rewards such as cash and honors for effective proposals.
• Special improvement team: To address issues such as high defective rates and complaints about delivery cycles, a QC team consisting of samplers, production supervisors, and quality control personnel was formed. The team used the PDCA cycle system to analyze and identify improvements one by one.
• Management Gemba Walks: Management regularly visits production sites to observe material flow and employee operations, identifying “waste invisible in the office” and promoting targeted improvements.

From order demand to finished product delivery, KML eliminates waste in every aspect of production through value stream optimization, making the process smoother.

• Visualize the entire process: Draw a value stream map of production plan issuance → material preparation → production line start-up → first-article verification → batch production → quality control, clearly marking the cycle time and potential waste points of each link.
• Eliminating waste: During preparation, the warehouse prepares materials according to the BOM with a two-person review. During mass production, IPQC conducts hourly inspections of key workstations to intercept defects early.
• Focus on bottleneck links: For key nodes, establish a triple confirmation among technical, production, and quality control departments to avoid batch stagnation due to first-piece problems.

To achieve uninterrupted production, KML started with production line layout and standardized operations to streamline LED lighting production:

• Collaboration before production line startup: Production pre-assigns personnel and work instructions, QC provides inspection standards, and the equipment team ensures machines/tooling/testing equipment are ready through cross-departmental joint audits.
• Standardized operations ensure flow: Clarify the operating standards, time, and quality requirements for each process so different employees operate more uniformly and reduce interruptions.

KML uses pull logic to organize production and procurement to avoid overproduction or stocking:

• Production side: Use order demand to drive production plans, clarify product models, quantities and delivery nodes, replace blind forecast-based production, and reduce finished-product inventory backlogs.

KML has established a full-staff improvement mechanism to transform lean practices from a management requirement into a daily habit:

• Proposals from frontline employees: Encourage production and quality control to propose small improvements and reward effective proposals.
• Special improvement team: QC teams use the PDCA cycle to analyze high defective rates and delivery complaints.
• Management Gemba Walks: Leaders visit the floor to find waste invisible from the office and drive targeted improvements.

The core of Lean implementation is people. KML empowers employees through layered empowerment, enabling them to become Lean practitioners:

• Tiered training: Targeted systems for production frontline, business teams, and managers so every level can understand and join lean.
• Empowerment and trust: Frontline staff may shut down production on quality anomalies; business teams can independently handle basic product issues to cut communication cost.

KML makes the lean improvement process measurable and traceable by quantifying and visualizing data.

• Define core lean indicators: production cycle, inventory turnover rate, defective product rate, customer complaint rate — each measurable and traceable.
• Visual display: Lean dashboards in the workshop show defective counts and first-article pass rate; ERP/dashboard surfaces procurement timeliness and supplier qualification rates.
• Data tracing and improvement: When turnover drops, data traces backlog causes and drives more precise pull-based procurement — a closed loop that keeps lean effects actionable.
