Fishbone diagrams would help a service organization determine the source of a quality-of-service issue. A fishbone diagram, also known as a cause-and-effect diagram or an Ishikawa diagram, is a tool for identifying and analyzing the root causes of a problem or an effect. It uses a fish-shaped diagram to display the potential causes of a problem in different categories, such as people, processes, equipment, environment, etc. A fishbone diagram can help a service organization to determine the source of a quality-of-service issue by allowing the organization to brainstorm and organize the possible factors that may affect the quality of the service delivered to the customers, such as staff training, customer feedback, service standards, equipment maintenance, etc. A fishbone diagram can also help the organization to prioritize and test the most likely causes, and to develop and implement solutions to improve the quality of service12.

A pull system in distribution management is a method of inventory replenishment that is driven by the actual demand of the customers, rather than by forecasts or schedules. In a pull system, each warehouse makes its own replenishment decisions based on the inventory level and the customer orders. A pull system reduces the risk of overstocking or understocking inventory, as it responds to the real-time demand fluctuations. A pull system also improves the efficiency and flexibility of the distribution network, as it eliminates the need for centralized planning and coordination. A pull system is suitable for products that have high demand uncertainty, low holding costs, or short lead times12.
