NON TECHNICAL MISTAKE PROOFING

COLOR CODING OF CHANGE PARTS WUPPERTAL

Before 4 different types of parts needed for

the conveyor belt of a packaging line

80 parts per belt

all the same color but different in shape

one wrong part could result in deformed

tampons and or missing tampons

After through color coding of the different

parts, misplacments are eleminated

NON TECHNICAL MISTAKE PROOFING

EXAMPLE: UPGRADE WORK INSTRUCTIONS

37

BEFORE AFTER

Simplified & Intuitive Instructions Strengthened Correct Operations

Also Improved Training Delivery Effectiveness!

NON TECHNICAL MISTAKE PROOFING

EXAMPLE: VISUAL AID & CENTER LINES

What is missing? Normal pressure range

Normal speed of pump range
