Process Improvement Chart is an official business term used to describe a compilation of data that tracks changes and improvements in a system’s performance over time. It is used to assess the effectiveness of a system in terms of its efficiency, cost, and overall performance. A Process Improvement Chart typically has multiple points of data that measure the performance of a system over time. These points of data can include the number of errors, average speed, time to complete, customer satisfaction, and other variables. By tracking this data over time, companies can measure the success of their process as well as identify areas for improvement. This data can also be used to identify problems, such as bottlenecks, and take corrective action. The Process Improvement Chart is a valuable tool for businesses, as it allows them to track the progress of their processes and determine where they can make improvements.
