Production and supply chain process MIS2101: Management Information Systems Based on material developed by C.J. Marselis
At Fitter Snacker, production manager schedules production based on experience, rather than formal planning techniques
MRP and ERP • What is MRP and what does it have to do with ERP?
Facilitating the production plan • What kind of questions does the production plan answer? • A successful company must be able to • Develop a good production plan • Execute the plan • Make adjustments when customer demand differs from the forecast
Production Approaches Make to Stock Make to Order Assemble to order
Mixer Snack Bar Line Mixer Form Bake Pack Raw Material Warehouse Finished Goods Warehouse Mixer Mixer Mixes 4,000 lbs/hr Excess capacity to ensure line doesn’t shutdown • Produces • 200 bars/minute, 3,000 lb/hr Operates 1 8-hour shift per day Changing from NRG-A to NRG-B bars takes 30 minutes
Production Problems in “Un-integrated” systems Inventory Accounting Communication What are some of these problems?
Production planning process • What are the major steps in the production planning process?
An integrated process Predicts future demand for products Determines what company should produce Requires starting inventory levels and sales forecast based on capacity Break production plan down into smaller time increments Determines amount and timing of raw material orders Create production schedule based on production plan from demand management Takes quantity and timing information from MRP and creates orders for suppliers Uses the schedule to determine products and staffing
Sales Forecasting Starting Inventory Sales and Operations Planning Demand Management MRP Detailed Scheduling Production Purchasing
Simple Sales Forecast • In an integrated system, where do I get the information to support my sales forecast?
Sales and operations planning – SOP or S&OP • What question does S&OP answer?
Demand Strategies • If demand is greater than capacity…
Forecasting in an Integrated System • Accurate historical sales values available for forecasting • “Fix” historical sales: • If production was unable to meet demand sales does NOT represent actual demand • Unusual conditions like weather • The effect of sales promotions Sales provided from SD module Field where planner can “correct” the sales value
Sales and Operations Planning (SOP) Case Study • Kellogg’s achieved significant savings from coordinated sales and operations planning (SOP) • Changed focus based on how they were evaluated • Marketing and sales: Evaluated on tons of cereal sold • Manufacturing: Evaluated on tons of cereal produced • No one evaluated on profit! • Kellogg’s new sales order process focused on profit • Kellogg’s has reduced capacity, inventory and capital needs while increasing sales

Demand Management • What does “Demand Management” do? 4/22 represents how many work “weeks” are in each month

Bill of Material • What is a BOM?
Lead Times and Lot Sizing • When it comes to purchasing raw materials, what are… • “Lead Times”? • “Lot Sizes” and why do I care?
Options to evaluate vendors Purchasing and ERP • What benefits do I get if my production planning system is integrated with my procurement system? Convert MRP data to a purchase order
Production and Accounting in an Integrated System • What benefits do I get when my production systems are integrated with my accounting systems? Material received (for MRP) and the purchase order
Implications for Supply Chain Management • How quickly does information flow from the retailer all the way back to the raw materials suppliers when demand changes in: • Non-integrated system? • Integrated system?
Supply Chain Integration • What kind of benefits do I get when I integrate my supply chain with my “partners”?
Top Line Versus Bottom Line Where do Supply Chain Systems add value?
Inventory Control Case Study – Hoyt Archery • Pre ERP, complete inventory count two times each year • Closed plant for 3 days at cost of $5000 /day • Post ERP, accurate, real-time inventory information and ongoing cycle- counting process: items are counted each day • Hoyt also simplified customer interaction with its configure-to-order (CTO) process
SCM with Customer Collaboration Case Study – Wal-Mart • POS data from bar code scanners is recorded in a massive data warehouse at Wal-Mart headquarters • Wal-Mart uses data mining techniques to predict what customers will buy at different times of the year • Data is shared with Wal-Mart suppliers to plan production • Wal-Mart also allows its 5000 suppliers to directly access its data warehouse through its Retail Link program • Wal-Mart is leading the effort to leverage RFID technology
SCM Critical Success Factors • Business-driven strategy – Focus on customer • Management Commitment – From the business and IT, not an IT project! • Supplier/Partner Expectation Management • Internal Expectation Management • Learning Period Acceptance
Summary • An ERP system can improve the efficiency of production and purchasing processes • Begins with Marketing sharing sales forecast • Production plan is created based on forecast and shared with Purchasing so raw materials can be ordered properly. • Production planning can be done without an integrated system, but integrated system that allows MRP and Production to be linked to Purchasing and Accounting
