10 PRODUCT DESCRIPTION The Acme Lifeline Emergency Cart (LEC) is a fully functional crash cart designed from the ground up to meet the critical demands of a hospital “code.” A “code” is among the most critical of all hospital emergencies. Efficient code response saves time and lives, and that is where a LEC unit comes into play.

11 LEC’s FEATURES Quick, safe transport of vital supplies to the code sites. Quick, safe transport of vital supplies to the code sites. Simultaneous access by multiple code team members.

12 PROBLEM STATEMENT assembly Acme’s Lifeline Emergency Cart (LEC) assembly line resembles a traditional batch and queue operation. Due to competition and rising production costs, Acme is forced to implement new systems and approaches to increase productivity and quality at lower cost. Team has selected Rotational Molding Machine operations, a critical area of current operations, and will present a proposal to improve quality and productivity.

13 OBJECTIVES Improve Safety and Ergonomics Improve Safety and Ergonomics - Improve GSIC score by 90% - Improve GSIC score by 90% - Improve 5S Score by 425% to achieve 85% - Improve 5S Score by 425% to achieve 85% Improve Quality Improve Quality - Reduce scrap by 85% - Reduce scrap by 85% - Determine Process Capability - Determine Process Capability - Redesign Product according to Process - Redesign Product according to Process Capability where needed Capability where needed - Improve Process Capability where needed - Improve Process Capability where needed (warp & shrink?) (warp & shrink?) - Achieve and maintain a minimum of 1.33 CPK of - Achieve and maintain a minimum of 1.33 CPK of all Critical to Quality Parameters all Critical to Quality Parameters

14 OBJECTIVES – cont. Reduce Costs with new techniques -Reduce scrap by 85% Acquire proper tooling Develop Preventive Maintenance System
