 Improvement Results of Project Y & y:
 Before : SLOB Material : 678 Mil After : Result : 637 Mil vs. target : 644 Mil end of
2012
 Benefits Delivered:
 Release space for Warehouse storage
 Contribute : 41Mil Direct Saving

Team workChange mindset
KEY LEARNINGS
D M A I C
LIXIL VALUES
Optimizes resource : Reach that Lixil value when we reduce Material SLOB value to contribute
direct saving for company
Release space when warehouse storage capacity is limited
Reduce write off list value for SLOB when they becoming damaged since kept a long time.
Changing mindset with logical thinking &
analysis method efficiency when apply Six
Sigma
Well knowledge planning & inventory
management are shared base on team work
