 Long lead-time items are items that take a long time to procure, produce, or deliver. Stable demand means that the demand for these items is predictable and does not fluctuate much over time. A supply chain that supports long lead-time items with stable demand would best be designed to position inventory close to the consumer, because this would reduce the delivery time and improve the customer service level. Positioning inventory close to the consumer also reduces the transportation costs and risks associated with long-distance shipments. A supply chain that uses a pull system, which is based on actual customer orders rather than forecasts, may not be suitable for long lead-time items, because it may not be able to meet the customer demand in a timely manner. A supply chain that is linked through an enterprise resources planning (ERP) system, which is a software system that integrates various business functions and processes, may improve the visibility and coordination of the supply chain, but it does not necessarily reduce the lead time or position inventory close to the consumer. A supply chain that is designed to be responsive, which means that it can quickly adapt to changes in demand or other variables, may not be necessary for long lead-time items with stable demand, because these items have low demand uncertainty and variability. References:

Customer relationship management (CRM) is a program that uses data and technology to manage the interactions and relationships with customers. CRM helps to understand the needs, preferences, and behaviors of customers, and to provide them with better products, services, and experiences. In a rapidly changing business environment, a primary advantage of an effective CRM program is earlier identification of shifts in customer preferences. This means that CRM can help to detect and anticipate the changes in customer demand, tastes, or expectations, and to respond accordingly. This can help to improve customer satisfaction, loyalty, and retention, as well as to gain a competitive edge in the market. CRM does not necessarily reduce forecast variability, which is the degree of difference between the actual demand and the forecasted demand. CRM does not necessarily reduce customer order changes, which are the modifications or cancellations of orders by customers. CRM does not necessarily reduce customer defections, which are the losses of customers to competitors or other alternatives. References: CPIM Exam Content Manual Version 7.0, Domain 3: Plan and Manage Demand, Section 3.1: Demand Management Concepts, p. 16; Customer relationship management; Customer Relationship Management (CRM) Definition.

A chase operational strategy is one that adjusts production to match the demand pattern. This means that the inventory level is kept low, as the output is synchronized with the demand. This reduces the inventory cost, as there is less need for holding, ordering, and carrying inventory. A chase strategy also minimizes the risk of obsolescence, spoilage, or excess inventory.

A level operational strategy is one that maintains a constant output rate, production rate, or workforce level. This means that the inventory level fluctuates, as the output may not match the demand. This increases the inventory cost, as there is more need for holding, ordering, and carrying inventory. A level strategy also increases the risk of stockouts, overstocking, or waste.

A mixed-model operational strategy is one that produces several products with the same resources. This means that the inventory level varies, as the output depends on the product mix and the demand. This may increase or decrease the inventory cost, depending on the product characteristics, demand variability, and resource utilization. A mixed-model strategy also requires more flexibility and coordination in production planning and scheduling.

A hybrid operational strategy is one that combines elements of chase and level strategies. This means that the inventory level is balanced, as the output is partly adjusted to the demand and partly kept constant. This may increase or decrease theinventory cost, depending on the degree of adjustment and constancy. A hybrid strategy also requires more trade-offs and compromises in production decision making.

Up-to-date information about production order status is required to calculate the cost of work in process (WIP). WIP is the inventory of unfinished goods or partially completed products that are still in the production process1. The cost of WIP is the sum of the costs of the materials, labor, and overhead that have been incurred in the production process but have not yet been transferred to the finished goods inventory2. To calculate the cost of WIP, we need to know how much of each production order has been completed and how much remains to be done. This information can be obtained from the production order status, which is a report that shows the current status of each production order in terms of its quantity, start date, end date, completion percentage, and variance3. By using the production order status, we can determine the amount of WIP for each production order and for the entire production process. This can help us monitor and control the production efficiency, profitability, and quality4.

Manufacturing flexibility can be measured by using changeover time. Changeover time is the time it takes to go from the last good part of one product run to the first good part of the next product run1. Manufacturing flexibility is the ability of a system to handle a range of products or variants with fast setups2. By using changeover time as a measure of manufacturing flexibility, we can assess how quickly and efficiently a system can switch from one product to another, and how well it can respond to changes in customer demand, product mix, quality standards, and delivery schedules3.

Some of the benefits of reducing changeover time and increasing manufacturing flexibility are4:

Lower manufacturing costs: More value-added capacity can be unlocked because the equipment is idle for less time.

Higher customer satisfaction: Customers can get their products faster and with more variety.

Greater competitive advantage: The system can adapt to market changes and offer more customized products or services.

Improved quality and productivity: The system can avoid defects, waste, and errors that may occur during long or complex changeovers.

Some of the methods or tools that can help reduce changeover time and increase manufacturing flexibility are5:

Single-minute exchange of die (SMED): A technique that aims to reduce changeover time to less than 10 minutes by converting internal setup activities (those that can only be done when the machine is stopped) to external setup activities (those that can be done while the machine is running), and streamlining both types of activities.

Total productive maintenance (TPM): A technique that involves maintaining and improving the equipment performance and reliability by involving all employees in preventive maintenance, autonomous maintenance, focused improvement, and quality management.

Quick response manufacturing (QRM): A technique that focuses on reducing lead times throughout the entire organization by applying the principles of time-based competition, cellular manufacturing, system dynamics, and enterprise-wide application.

Therefore, changeover time is a measure that can be used to evaluate the manufacturing flexibility of a system.
