1. 1/9/09 System Level Design Review January 16, 2009 Aaron Heyman – Lead Adam Cook Jose Rodriguez Abraham Taleb

2. Team Expectations for Design Review Learn if Costumer Needs are being met Catch any mistakes in design Receive input on user interface Confirm coherence between all involved parties to create the best end product 1/9/09

3. Agenda Review Goals of Project Project Status Customer Needs Assumptions, Constraints and Risk Assessment Discussion of User Interface

4. 1/9/09 Goals of Project Be able to answer the following question: o How many labor hours does CooperVision need per pick area given demand in terms of lines for a particular time segment (daily, weekly, monthly, yearly)? Process Improvements will be identified and investigated beginning in March

8. 1/9/09 Assumptions & Constraints Pick per area distribution is constant Capacity analysis only applies to pick areas not packing/shipping SKUs are always in stock Unable to pull data with out IT assistance No budget to make improvements unless approved Picking system and design constraints

9. 1/9/09 Risk Assessment Risk ItemLevelOwnerStatus and/or Contingency Plans Optimizing part of the system and not the whole. MediumCooperVisionThe team will optimize the pick area to the best of their ability. The entire distribution process is beyond the project scope. Validating the computer tool. HighTeamThe team plans on using historical data to validate the model. Creating an easily modifiable computer tool. MediumTeamThe team will use excel for the computer tool due to its popularity with the customer. Missing data that is needed for calculations. LowTeamThe team has requested all data and has been receiving it in a timely manner from the customer.
