    • Freight equalization.

    • Basing point pricing.

Customer Service Defined

Customer service is generally presumed to be a means by which companies attempt to differentiate their product, keep customers loyal, increase sales, and improve profits.

It’s elements are:

  • Price.

  • Product quality.

  • Service.

It is an integral part of the marketing mix of:

  • Price.

  • Product.

  • Promotion.

  • Place (Physical Distribution).

Most Important Customer Service Elements

  • On-time delivery.

  • Order fill rate.

  • Product condition.

  • Accurate documentation.

Order Cycle Time

Order cycle time contains the basic elements of customer service where logistics customer service is defined as:

The time elapsed between when a customer order, purchase order, or service request is placed by a customer and when it is received by that customer.

Order cycle elements

  • Transport time.

  • Order transmittal time.

  • Order processing and assembly time.

  • Production time.

  • Stock availability.

Order cycle time is expressed as a bimodal frequency distribution.

Constraints on order cycle time.

  • Order processing priorities.

  • Order condition standards (e.g., damage and filling accuracy).

  • Order constraints (e.g., size minimum and placement schedule).

Service Observations

  • The dominant customer service elements are logistical in nature.

  • Late delivery is the most common service complaint and speed of delivery is the most important service element.

  • The penalty for service failure is primarily reduced patronage, i.e., lost sales.

  • The logistics customer service effect on sales is difficult to determine.

Modeling a Sales-Service Relationship

  • A mathematical expression of the level of service provided and the revenue generated.

  • It is needed to find the optimal service level.

  • A theoretical basis for the relationship.

Sales-Service Relationship by the Two-Points Method

Cost-Revenue Tradeoffs

Determining Optimum Service Levels

  • Cost vs. service.

Theory

  • Optimum profit is the point where profit contribution equals marginal cost.

Practice

For a constant rate:

Example

Given the following data for a particular product

  • Sales response rate = 0.15% change in revenue for a 1% change in the service level (fill rate)

  • Trading margin = $0.75 per case

  • Carrying cost = 25% per year

  • Annual sales through the warehouse = 80,000 cases

  • Standard product cost = $10.00

  • Demand standard deviation = 500 cases per week

  • Lead time = 1 week

Setting Service Levels

  • Service is treated as a constraint on design.

  • Planning for service contingencies.

Measuring Service Performance

  • Percent of sales on backorder.

  • Number of stockouts.

  • Percent of on-time deliveries.

  • The number of inaccurate orders.

  • Order cycle time.

  • Fill rate--% of demand met, % of orders filled complete, etc.

Service Contingencies

System Breakdown Actions

  • Insure the risk.

  • Plan for alternate supply sources.

  • Arrange alternate transportation.

  • Shift demand.

  • Build quick responses to demand shifts.

  • Set inventories for disruptions.

Product Recall Actions

  • Establish a task force committee.

  • Trace the product.

  • Design a reverse logistics channel.
