Inventory days of supply (IDS) is a measure of how long it takes for a company to sell its entire inventory. Reducing IDS means that the company is selling its inventory faster, which increases the inventory turnover ratio. Inventory turnover ratio is the number of times a company sells and replaces its inventory in a given period. A higher inventory turnover ratio indicates that the company is more efficient in managing its inventory and generating sales. Reducing IDS also means that the company is reducing the time between paying its suppliers and receiving payment from its customers, which reduces the cash-to-cash cycle time. Cash-to-cash cycle time is the number of days a company’s cash is tied up in its operations. A lower cash-to-cash cycle time indicates that the company is more efficient in converting its inventory into cash and improving its liquidity. Therefore, reducing distribution network inventory days of supply will have the impact of increasing turnovers and reducing cash-to-cash cycle time. References:

 The production supervisor is the most appropriate person to send the information about the overage in actual run time for one operation. The production supervisor is responsible for overseeing the execution of the production plan and ensuring that the operations are performed efficiently and effectively. The production supervisor can review the actual run time data and compare it with the planned run time, identify the possible causes of the overage, and take corrective actions if needed. The production supervisor can also explain the overage to the cost accountant and other stakeholders, such as the product manager, the quality manager, and the engineering manager, and provide feedback for improving the planning and routing of the operation. References:

A statistical safety stock calculation is based on the assumption that demand and lead time are normally distributed and independent. This method is suitable for end items with stable demand, as it can provide a reasonable estimate of the required safety stock to achieve a desired service level. Therefore, option C is correct. Option A is incorrect because components used in multiple end items may have dependent demand, which means that their demand is derived from the demand of the end items. Dependent demand may not follow a normal distribution and may require a different method of safety stock calculation. Option B is incorrect because new products at time of introduction may have uncertain or variable demand, which makes it difficult to apply a statistical safety stock calculation. Option D is incorrect because supply-constrained raw materials may have long and variable lead times, which also complicates the use of a statistical safety stock calculation. References: CPIM Part 2 Exam Content Manual, Version 8.0, Section E: Plan and Manage Inventory, Subsection E.2: Inventory Management Methods, p. 54.
