Overall Equipment Effectiveness, commonly known as OEE, is one of the most important performance indicators used in Lean Manufacturing to measure how efficiently manufacturing equipment is utilised. OEE helps organisations identify losses, improve productivity, reduce downtime, and increase output without additional investment. In automotive, engineering, and process industries, OEE is widely used as a core … Read more
PPAP full form is Production Part Approval Process. PPAP is a structured quality approval process used in the automotive industry to ensure that suppliers can consistently manufacture parts that meet customer requirements. PPAP is a core requirement of IATF 16949 and is mandatory for OEMs, Tier-1, and increasingly Tier-2 suppliers. This article explains PPAP, PPAP … Read more
The 3G Principle—Genchi Genbutsu, Gemba, and Genjitsu—is one of the strongest foundations of Japanese manufacturing. It is widely used in the Toyota Production System (TPS), lean manufacturing, and automotive industries for accurate decision-making and root cause identification. When any abnormality, defect, breakdown, or customer complaint appears, leaders instruct teams to “Go to the Gemba and … Read more
Product and process audits are essential quality assurance tools used across manufacturing industries, especially in automotive OEMs and Tier 1 suppliers. These audits verify whether processes follow the defined standards and whether the final product meets customer requirements. In the automotive sector governed by IATF 16949, both process audits and product audits play a critical … Read more
Single Minute Exchange of Dies (SMED) is one of the most powerful lean manufacturing tools used to reduce machine changeover time, increase productivity, and improve overall equipment effectiveness (OEE). Many industries such as sheet metal, plastics, injection molding, press shops, die casting, forging, packaging, and CNC machining use SMED to reduce setup time from hours … Read more
A Control Plan is one of the most important documents in manufacturing and quality management. It ensures consistent production, reduces variation, prevents defects, and helps maintain process stability over time. Whether you work in automotive, engineering, machining, fabrication, plastics, or process industries, a well-designed Control Plan is essential for delivering quality products with repeatable results. … Read more
In any manufacturing plant, automotive industry, service operation, or technical system, monitoring the reliability and maintainability of equipment is essential. Two of the most widely used metrics for this purpose are Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR). These metrics help answer two fundamental questions: Understanding MTTR and MTBF helps maintenance … Read more
What is a Control Chart? A Control Chart is a statistical tool used in quality control to monitor how a process changes over time. It helps determine whether a process is stable, predictable, and operating within set control limits. A control chart has: If the process stays within UCL and LCL, the process is in … Read more
In the competitive world of automotive manufacturing, consistent quality and compliance aren’t just expectations — they are survival essentials. Every Tier 1 and Tier 2 supplier knows the weight an IATF 16949 audit carries. It determines not only certification but also business continuity with OEMs like MSIL, Honda, or Tata Motors. Yet, many capable organizations … Read more
Introduction In Lean Manufacturing, one of the biggest barriers to efficiency is waste, also known as Muda in Japanese. These wastes increase cost, reduce productivity, and slow down your entire process.This guide explains the 8 types of waste in Lean Manufacturing — from overproduction to defects — along with practical examples and strategies to eliminate … Read more
