Lot splitting is the technique of dividing a lot into smaller sub-lots that can be processed concurrently, especially when multiple machines are available. This strategy significantly reduces overall lead time by processing portions in parallel instead of sequentially.

“Lot splitting results in the shortest overall lead time… reduces total span time.”

Customer service performance is the degree to which a company meets or exceeds the expectations of its customers in terms of the quality, timeliness, and satisfaction of the service provided. The most relevant measure of customer service performance is the service perceived by the customer against the service expected by the customer, also known as the service quality gap. This measure captures the difference between what customers expect from a service and what they actually receive, and reflects the level of customer satisfaction or dissatisfaction. A positive service quality gap indicates that the service exceeded the expectations, while a negative service quality gap indicates that the service fell short of the expectations. The other options are not as relevant as the service quality gap because they do not account for the customer’s perspective or perception of the service. Service promised to the customer against service measured by the supplier is an internal measure of service performance, but it does not reflect how the customer perceives the service. Customer complaints received as a percentage of orders shipped is a measure of service failure, but it does not capture the positive feedback or the silent dissatisfied customers. Positive customer feedback as a percentage of customer feedback is a measure of service satisfaction, but it does not account for the customer’s expectations or the service quality dimensions. References:

20 Customer Service KPIs You Need To Know

A Fourth-Party Logistics (4PL) provider assumes broader roles than a traditional third-party logistics (3PL) provider. It is not only responsible for the physical movement of goods but also for managing the supply chain as a whole, including coordination between the client and multiple logistics service providers.

“Companies that not only take on the responsibility of the physical movement of goods between a supplier and a customer but also take more of the supply chain service requirements are called a fourth-party logistics company.”

Independent demand for components and subassemblies is not tied to the demand of a higher-level item. These typically come from repair, maintenance, and service activities, where components are needed on their own rather than as part of a finished product.

“Independent demand... includes service/replacement parts and maintenance repair operating supplies.”

Increasing finished goods inventory investment will improve service levels by reducing the probability of stockouts. However, the relationship between inventory and service level is not linear, but rather asymptotic. This means that as inventory increases, service level increases at a decreasing rate, approaching a maximum value. Therefore, option C is correct. Option A is incorrect because service level will not remain the same when inventory changes. Option B is incorrect because service level will not increase in direct proportion to inventory. Option D is incorrect because service level will not increase at an increasing rate as inventory increases.
