12Kaizen TrainingDifferent Types of ActivitiesBeing able to tell the difference between NVA and VAactivities is an important step in the Improvement Process.Value AddedActivity (VA)An activity that changes rawmaterial to meet customerexpectations.Non Value AddedActivity (NVA)Those activities that taketime, or occupy space butdo not add to the value ofthe product.You must ask yourselves “Would you as a customer bewilling to pay for any NVA activity being performed to thatNEW 4x4 Pickup you just ordered?”

5 ‘S’ in KAIZEN5 ‘S’ in KAIZEN• 5S is a method for organizing aworkplace, especially a sharedworkplace (like a shop floor or anoffice space), and keeping itorganized.• To take the concept of Kaizenperformance to its ultimate level ofsimplicity, it offered the following "5S"steps• Sorting keeping onlyessential items• Simplifying eliminates extramotion.• Sweeping keep theworkplace clean• Standardizing standardizedwork practices• Sustaining maintaining and reviewingstandards• .
BENEFITS OF KAIZANBENEFITS OF KAIZAN• Kaizen Reduces Waste- likeinventory waste, time waste,workers motion• Kaizen Improves spaceutilization, product quality• Results in higher employeemoral and job satisfaction, andlower turn-over.• Toyota is well-known as one of theleaders in using Kaizen. In 1999 atone U.S. plant, 7,000 Toyotaemployees submitted over 75,000suggestions, of which 99% wereimplemented..
Before Kaizen• Componentskept underworkstation
After Kaizen• Tooling bins areeasily traceable
Pitfalls in KAIZENPitfalls in KAIZENResistance to changeLack of proper procedure to implementToo much suggestion may lead to confusion andtime wastage
