Layered Process Audit (LPA) is an easy-to-understand and quick-to-implement auditing method based on checklists that focuses on the execution of processes. These audits take only a few minutes, occur frequently, and are conducted internally by leaders from different hierarchical levels involved in the process. Deviations are corrected immediately, and the results of the audit are visually presented on-site. With this guide, you will receive a concrete roadmap to implement this innovative auditing method step by step. Numerous examples, checklists, and practical tips will facilitate your transfer to practice. "Through LPA, I quickly gain an overview of potential improvements, problems, and stagnations."
