Agenda • Effective Inventory Management • Strategic Considerations • Supply Chain Management • Purchasing and Production • Sales and Customer Service • Suppliers and Customers • Inventory Accuracy • Cycle Count Strategies
Competing Objectives…. • Sales/Marketing/Customer Service Objective • Maintain sufficient on hand inventory to satisfy every possible (or impossible) customer request • Production Objective • Maintain on hand inventory quantities that produces the lowest cost per unit • Inventory Management Objective • Maintain lowest level of on hand inventory to satisfy customer demand while minimizing cost
….Producing Different Results • Sales/Marketing/Customer Service Objective • Maintain sufficient on hand inventory to satisfy every possible (or impossible) customer request • Results in on hand inventory for every SKU available in large quantities consuming a large amount of space • Production Objective • Maintain on hand inventory quantities that produces the lowest cost per unit • Results in maintaining large quantities of low cost SKU’s on hand but not specialty/unique SKU’s that customers demand • Inventory Management Objective • Maintain lowest level of on hand inventory to satisfy customer demand while minimizing cost • Results in maintaining appropriate amounts of each SKU on hand to ensure customer demands are adequately met
Cost of Excess Inventory • Carrying Cost • $5,000,000 x 6% interest cost = $300,000 carrying cost • Hidden Costs • Warehousing and Rent • Labor Costs (moving, counting, maintaining) • Cash flow considerations • Quality

Purchasing and Production • Purchase and manufacture based on customer demand – NOT BASED ON VOLUME DISCOUNTS OR UNIT COST CONSIDERATIONS • Map the purchasing and production processes identifying non-value added activities, bottlenecks, constraints, etc. • Strengthen your Preventive Maintenance program • Results in more reliable production and quality • Maintain discipline in the Engineering group • BOM accuracy • Engineering changes
Sales, Marketing, and Customer Service Map the sales forecasting and sales order processes identifying non-value added activities, bottlenecks and constraints Commit to SKU Rationalization using historical data with up-front sales team involvement Compensation plans should be built around selling profitable SKU’s
Suppliers and Customers Suppliers • Reduced lead times • Quality inspections prior to shipment • Shipment accuracy Customers • Cooperative forecasting • On-line, real time order to shipment tracking
Accounting and Finance • What can I do differently? • If your company is Lean or Six Sigma, participate in Kaizen events • Facilitate discussions between sales, production, purchasing, etc. • Lead change either through the Internal Audit function or CFO leadership
Inventory Accuracy: How to Improve • What is Inventory Accuracy? • Inventory record accuracy is a measure of how closely official inventory records match the perpetual inventory levels. • Inventory Accountability Measures • Accountants and financial personnel prefer dollar based measurements of accuracy. • Operations and material management personnel have a stronger interest in the accuracy of individual item or SKU.
Inventory Facts Inventory is often the largest consumer of capital for an enterprise. It is imperative that a business have accurate inventory records to be effective and efficient. Poor inventory accuracy may cause stock-outs of inventory and require a business to carry higher inventory levels than necessary, which requires more capital.
Common Inventory Accuracy Issues • Common causes for inventory inaccuracy • Shop floor discipline • MRP set-up is not accurate • Accounting for subassemblies / kits / phantoms • BOMs are not followed in production • High volume of facility transfers • Ineffective root cause analysis of inventory issues
Advantages of Cycle Counting Program • Cycle Counting discovers errors in the perpetual inventory records much like a physical inventory. • Significant advantages of cycle counting over the physical inventory: • Allows for the achievement and sustainability of very high accuracies • Spreads out the counting workload
Advantages of Cycle Counting Program (continued) • Allows for the reduction of inventory • Continuously measures accuracy • Continuous - Works without interrupting of operations • Facilitates process improvement through root cause analysis • Can eliminate the need for an annual inventory observation
Downfalls of a Physical Inventory Observation High degree of accuracy achieved Expensive Requires a large investment of physical resources Not sustainable Significant impact on operations Cannot conduct ongoing root cause analysis over inventory outages
Cycle Counting Program – Basic Operation Cycle counting continually finds and corrects inventory record errors Counters inspect a small sample of inventory items each day Cycle count selection is random or semi-random based on established methodology Errors are immediately corrected
Cycle Counting Program – Basic Operation • Multiple variables affect the number of daily or weekly counts that will be required such as: • Population of inventory / number of SKUs • Desired accuracy level • Timeline for achieving accuracy goals • Current state of inventory • Warehouse organization
Cycle Counting Program – Designing Yours Number of counts required Number of personnel available Timing of counts Resource availability (forklifts, scales, etc.) Counting method (counts sheets, RFID, etc.)
Cycle Counting Program – Designing Yours RubinBrown will email examples of cycle counting instructions to all webinar participants in addition to the presentation by the end of the week.
Cycle Counting Program – Methodology • Several methods exist that can help estimate the initial number of counts that will be required. They are all approximate. • Planners and system designers should use several or all of them to home in on the best initial estimate. • 50% - 60% of all companies use a combination of methods to complete their cycle counts • Source: APICS – Association for Ops Mgmt
Cycle Counting Program – Methodology • ABC Classification • Random counts • Targeted Selection • Zero quantity or negative quantity counts • Discrepancy based counts • Explicit counts • Minimum on hand
Cycle Counting Program – ABC Classification and Physical Observation
Cycle Counting Program – ABC Classification and Cycle Counts
Cycle Counting Program – Pitfalls • No formal cycle count program / methodology in place • Inventory ownership – Ownership / responsibility of inventory accuracy is in the wrong hands • Insufficient Resources • Trained Personnel • Equipment
Cycle Counting Program – Pitfalls (continued) • Segregation of duties • Packaging – Paperwork and labeling in poor condition • Unit of Issue • System tracking compared to physical • Boxes / Bags vs. Eaches • Rolls / Coils vs. Feet / Yards • Non-standard packaging from suppliers
Financial Statement Audit Benefits • Depends on audit firm • Can be as reliable as annual physical inventory • Could eliminate annual physical inventory • Will not eliminate auditor test counts • Will not eliminate auditor need to visit multiple locations • Creates flexibility in timing of auditor counts
