Agenda • Company Background • Define • Measure • Analyze • Improve • Control • Conclusion
Description of XYZ • Company Description • A company that manufactures microprocessors and delivers to all over the world • Problem Areas • Long customer responding time – it takes between 2 days and 25 days until customers get response on order availability • Large amount of change order request • High volume of follow up calls / emails on order clarification
Charter SIPOC CTQ Tree Define Brainstorming Process Flow Diagram Flow Chart Project Gantt Chart
Brainstorming What areas can be improved? Takes long time for manufacturing site to work on build plan Takes long time for request to get to PSP Takes long time for customers to receive response Takes long time for BP to discuss with the fab Hard to accommodate when customers have to change orders Better meet customer’s demand
SIPOC Suppliers Inputs Process Outputs Customers • Order • Order form • Granting Tool • Packing • Client • CBA • GBA • PSP • Warehouse • See Below • Order Fulfillment • Client Step 1: Receiving Customer Order Step 2: Accumulation of Orders Step 3: Checking Inventory / Mfg if required Step 4: Committing Order fulfillment Step 5: Customer receives the products PSP – Product Supply Planner GBA – Geographical Business Analyst CBA – Customer Business Analyst BP – Business Planner
CTQ Tree In manufacturing, specification limits often come from technical or mechanical requirements, otherwise, the base specification limits on data about customer needs set the specifications where customer satisfaction starts to fall off noticeably CTQ Tree is used for · Unspecified customer requirements· Complex, broad needs NEED DRIVERS CTQ TREE New Decision Support GUI tools that improve the ability to fine-tune schedules to give better conformance to overall plans Enhanced scheduling Implementation of Business Intelligence Applications Making right decision in shortest time To reduce the lead time Build local sales office to replace existing single-site Faster and better communication lines Implementation of faster and multi-faceted Collaborative communication systems such as Telephone, mobile phone, internet chat Faster production of schedule More time for alternative scenarios of production, leading to better schedules and improved productivity
CTQ Tree…con’t NEED DRIVERS CTQ TREE Implementation of ERP/SCM systems Short wait time To reduce the analyzing time between BPs and Fab Real-time manufacturing/sales data Implementation of workflow- based Decision Support Systems and Data Mining tools Improved process-related guidance systems Provide updated information to Customer Reps PROVIDE Knowledgebale Customer Reps To provide Good Customer Service Implement a training routine Provide GUI tools to help make faster and correct decisions Implementation of data mining and analytical tools to provide accurate and current data

Root Causes in Fishbone Diagram • Long Process Flow • Lack of training • Inefficient analyzing tool • Lack of feedback / rating system • Inefficient real time inventory system
PDCA Flow process diagram Improve Communication Plan
PDCA • DO • Pilot team will be setup and test the program • Record the total time needed to respond to customer requests • Record the number of error / complaints that occur • Record the amount of change requests from customers • Check • Compare actual results with our expected results • Find out the reasons behind • Act • If actual = / better than expected, then standardize the process • Otherwise, determine root causes, improve the proposed process, try again!
