Warehouse Management:Measuring and Benchmarking Warehouse Performances
2
Warehouse Benchmarking
• Setting world-class performance, practices , and infrastructure goals for the warehouse operations
• WBM Permits quantitative assessment of the opportunity for improvement in– Productivity – Shipping accuracy – Inventory accuracy – Dock to dock time – Warehouse order cycle time – Storage density

Scheme of session
1. Benchmarking & its types?
2. Warehouse performance metrics
3. Warehouse Performance Gap Analysis (WPGA)

1. Benchmarking & its types?
Benchmarking?• Quantitative assessment of aspects of performance• Process popularized in late 80s ; Xerox Corporation• Aspects
– Internal – External – Competitive
5
1. Benchmarking & its types?Internal Benchmarking• Focused on the operations of a single company
Case of Gillette• Operation includes • Mexico , Chile ,Brazil ,Colombia, Argentina• Logistic managers are measured against key indicators:
– Shipping accuracy – Inventory turns– Fill rate– DC productivity– DC storage density– Order cycle time– Perfect order percentage
• Competition among group• Winner teach the group how he/she achieved that success
6
1. Benchmarking & its types?
2. External Benchmarking• Looks outside the firm’s industry
Case of Xerox Service Parts• Embarked on major DC reconfiguration• Arranged tours of a variety of DC facilities • Exchanged information from the host company• Performance measurement frame work
– Lines shipped per person hours– High score facilities; a beacon of guidance
• Focal; L.L. Bean (retail)• Process worked and Xerox Chicago DC has achieved Modern
Material Handling’s annual productivity achievement award
7
1. Benchmarking & its types?
• Xerox looked outside the industry• ECR in the grocery is the take-off on QR of Textile
industry• QR is a take-off of JIT from the Japanese automotive
industry• Carousels DC take-off of dry clean industryHow• Benchmarks with logistically similar company
– Order value– Average order cube – Average number of items on an order– Transaction volume
8
1. Benchmarking & its types?
Case of SBC Telecommunication• Task to reduce material cost by 20 percent maintaining service level• Logistics benchmarking partnership
– SBC (t.c), John Deere (agro machinery), United Stationers & Excel Logistics
• Comparison by developing questionnaire• 12 questions from each company• Identified ULP of each company
– John Deere’s work measurement & safety– SBC; customer service excellence– US productivity– Excel ; Quality performance
• Teach ULP to other partner

1. Benchmarking & its types?
3. Competitive Benchmarking
• Assessment of company’s logistics performance with competitors
• Case of wholesale distributor of Health care
10
2. Traditional WBM metrics
• Operating cost – Warehousing and/or Distribution cost as percentage of sale
• Operating productivity– Measured in units lines, orders , pieces and pallets etc handled
per person hour
• Customer response time• Shipping accuracy• Annual Warehousing cost
– Labor cost (material handling, annual) [labor hrs X WR]– Space cost (storage) [square ft occupied X annual cost of space]– System cost (information handling) [system investment cost X
annual amortization/ depreciation rate
11
2. Traditional WBM metrics
Integrating all ,Four important measure A. Warehouse Financial Performance B. Warehouse Productivity Performance C. Warehouse Quality Performance D. Warehouse Cycle Time Performance
12
2. Traditional WBM metrics
A. Warehouse Financial Performance
• Warehouse activity based costing (ABC)
13
14
2. Traditional WBM metrics
B. Warehouse Productivity Performance• Productivity
– Labor– Space– Material handling system
• Labor periodicity: – Ratio of units , orders, lines or weight shipped out of the
warehouse TO the number of hours spent in operating, supervising, and managing the warehouse
• Storage Density– The Ratio of the amount of inventory storage capacity TO the
square footage inventory stored• Safety
– Occurrences
15
2. Traditional WBM metrics
C. Warehouse Quality Performance
• Four key indicators– Put away accuracy– Inventory accuracy– Picking accuracy– Shipping accuracy
16
2. Traditional WBM metrics
D. Warehouse Cycle Time Performance
• Dock-to-stock– Time elapse between shipment receiving at
warehouse to readiness for picking
• WHS Order Cycle Time (WOCT)– Time elapse between releasing order to WHS
floor to readiness for shipment
17
18
3. Warehouse Performance Gap Analysis
• Productivity – lines per hour
• Storage density – Case storage capacity per square foot
• Shipping accuracy – Percent line shipped in error
• Inventory accuracy • Dock-to-stock• Order Preparation Time (WOCT)

Warehouse Performance Index
o Material handling system investment vs Annual working labor hours
o Workforce demographics and Warehouse performance
o Warehouse size vs. Warehouse performance
o Level of mechanization & Warehouse performance
21
Warehouse automation & its dos and don'ts
– Automation can resolve complex issues– WHS practices training: is it a for granted
issue?– Analysis of live system– Use of CFT in performance evaluation– Compare & contrast operations– Mechanization & Flexibi9lity
22
World Class warehouse Practices
• Receiving• Put away• Reserve Storage• Picking• Slotting• Replenishment• Shipping• Work Measurement• Communication
