"We have observed the inventory system does not handle plastic parts well." What should be added to the problem statement to make it more useful?
Measurements are quantitative or qualitative data that indicate the magnitude, frequency, or impact of the problem. Measurements help to define the problem clearly, objectively, and specifically, as well as to establish a baseline for improvement. Therefore, what should be added to the problem statement to make it more useful is measurements that help describe the problem. For example, a more useful problem statement could be ''We have observed that the inventory system causes 15% of plastic parts to be damaged or misplaced every month, resulting in $10,000 of additional costs and 5% of customer complaints.''
In a lean environment, one uses material requirements planning (MRP) processing primarily to:
Which of the following approaches is most effective in communicating operational performance?
Visual control boards are tools that display the key performance indicators (KPIs) and metrics of a production system in a graphical and easy-to-understand format. Visual control boards are usually located at several locations within the production facility, such as the work centers, the shop floor, or the management office. Visual control boards help to communicate operational performance by providing real-time and relevant information, enabling quick feedback and corrective actions, and promoting transparency and accountability.
The other options are not the most effective approaches in communicating operational performance. Quality performance measures are indicators that evaluate the degree to which the products or services meet or exceed the specifications and standards. Quality performance measures are important for communicating operational performance, but they are not sufficient, as they do not cover other aspects of performance, such as cost, time, or customer satisfaction. Reviewing conformance to schedule is a method of comparing the actual production output with the planned production output, based on the master production schedule or the material requirements plan. Reviewing conformance to schedule is useful for communicating operational performance, but it is not timely, as it is usually done after the production is completed, and it does not provide enough details or explanations for the deviations or variances. Monthly meetings with employees are events that involve discussing and reviewing the operational performance with the staff members who are involved in the production process. Monthly meetings with employees are beneficial for communicating operational performance, but they are not frequent, as they are only held once a month, and they may not be effective, as they may lack participation or engagement from the employees.
Fishbone diagrams would help a service organization determine:
A fishbone diagram, also known as a cause-and-effect diagram or an Ishikawa diagram, is a tool for identifying and analyzing the possible causes of a problem or an effect. It is often used in quality management to find the root causes of defects or errors. A fishbone diagram has a main branch that represents the problem or effect, and several sub-branches that represent the categories of causes, such as people, processes, equipment, materials, environment, etc. Each category can have further sub-branches that represent more specific causes. A fishbone diagram would help a service organization determine the source of a quality-of-service issue by allowing them to visualize and organize the potential factors that contribute to the problem and identify the most likely cause.Reference: CPIM Part 2 Exam Content Manual, Domain 8: Manage Quality, Continuous Improvement, and Technology, Section 8.1: Quality Management Concepts and Tools, p. 59-60.
