Examples of Lean Six Sigma Cost Saving Improvements
1. HVAC DUCTING PRODUCTION CAPACITY INCREASE
DP largest unit production item are elbows (Galvanized, HVAC Duct Elbow)
Current capacity = 2.1 million elbows per year ( 2 shifts 5days + 2days OT)
Current demand has increased to 2.5 million of them per year.
Three possible solutions to the capacity short fall problem.
current cost per elbow is $0.68
Solution 1). add a third shift, cost per elbow $0.76
Solution 2). outsource the 440,000 elbows, cost is $0.82
Solution 3). Buy 3 new machines, cost to make is $0.62 with a payback in 1.3 years
Currently 1 operator runs 2 machines (manual labour intensive machines)
Improvement: Designed a 1 man cell to run 3 semi-auto machines simultaneously The payback =1.3 years with annual savings of $472K ($0.08 cost/pc reduction )
New machines designed for quick changeover <10min vs current 25min (efficiency gains).
RESULTS:
1 MAN CELL 3 MACHINES REDUCED LABOUR COST BY
TOTAL ANNUAL SAVINGS AFTER PAYBACK = $472K IN COST/PC REDUCTION

o Implemented SMED principles, 5S SHADOW BOARDS, standardized, Set-Up
o New water manifolds with shorter hoses and different IN/OUT connectors
o Standardized bolt lengths and utilized quick-connect clamps
o Interchangeable inserts and standardized back plates with different hole pattern
o Standardized Mould kits & implemented shadow boards
o Documented SOP and validated set-up/changeover on different shifts

7. LEAN LOGISTICS MANUFACTURING (DPM) AND DISTRIBUTION (NT) 2013-2014
Streamlined a complex Canada wide Manufacturing-Supply Chain-Logistics replenishment
operation, which reduced storage/transportation costs by $920K, inventory levels by $2.2Mil (from
$3.4Mil to $1.2Mil). Total Operational savings= $3.1Mil
Problem Statement:
Transportation Logistics from DP Manufacturing to NT Distribution centres inefficient. Customer same
day orders and replenishment being picked up from DP Manufacturing delivered to NT Distribution
Centre, then reloaded onto an outbound carrier resulting in either late deliveries, lost shipments or
delivered to wrong address, resulting in shortages 50%, high WIP levels and excessive transportation
costs.
Improvements:
Implemented Lean Logistics using 1-step cross-docking distribution from DP to final destination, which eliminated shortages, reduced delivery time from 4 days to < 1 day
Integrated Manufacturing-Supply Chain with Warehouse Management System which reduced
total WIP inventory by $2Mil, eliminated 2 carriers, utilized same carrier for Inbound/Outbound
Implemented Advanced shipping notice (ASN) which enabled Synchronized inbound delivery with
outbound shipments, bar code tracking with shipment RFID chips from supplier
