1. Mid-Quarter Design Review April 7, 2009 Aaron Heyman Adam Cook

2. Agenda Capacity Model (3.0) Changes since 2.8 Validation Process Overall Capacity What’s Next

3. Capacity Tool Global Changes Removal of Global units per line Added “Delay Allowance”  Calculated Effective Shift Length Added color coding to Max Workers

4. Capacity Tool Changes Pick Areas Removed unnecessary ADM input fields Identified and fixed error in ADM labor hour calculations New Pick Times (excludes breaks and lunch)

5. Validation Compared our calculated numbers against a one month sample of actuals Used Total Labor Hours as metric Calculated based on daily demand Results: Calculated labor hours were 5.5% less than actuals (avg. of all areas)

8. Overall Capacity Provided four options of presentation  MTBF/MTTR  Upper & Lower Bounds  Independent Areas  Bottleneck Identification Selection was a combination of Independent areas and Bottleneck ID

9. Overall Capacity ADM @ 95% uptime: 534 orders/hr PTL: 260 lines/hour/person Voice: 101 lines/hour/person Carousel: 206 lines/hour/person Bottleneck is a factor of pick times, people and demand in area

10. Next Steps Finalize Documentation for Capacity Tool Focus on Overall Capacity Analysis Addition of Pack to Capacity Tool  (If time allows)
