An In-Process Inspection (IPI) is a quality control process that involves monitoring and inspecting the production process as it is taking place. The goal of IPI is to identify and correct any issues with the production process before the final product is completed. This helps to ensure that the end product meets the required specifications and standards and is fit for its intended use.

IPI helps to identify and correct production issues before they become more significant problems. It also helps to ensure that the final product meets the required specifications and standards, reducing the risk of customer complaints, returns, and rework. By catching issues early in the production process, IPI can save time and money by avoiding the costs associated with fixing problems after the product is completed.
