Case Study: Sumida achieves paperless, transparent LPAs with Plan Brothers’ audits.io

Sumida Corporation - Customer Case Study

Sumida Corporation, a global automotive manufacturer, was managing layer process audits (LPAs) with pen, paper, and Excel, which made the process time-consuming and difficult to monitor. The company struggled with manual data entry, limited visibility into who completed each audit step, and inconsistent LPA coverage across locations. To address these issues, Sumida turned to Plan Brothers’ audits.io software.

Plan Brothers implemented audits.io to digitize Sumida’s LPAs across operations in Europe, South America, and Asia, replacing paper-based audits with an easy-to-use app. The solution improved data monitoring, enabled follow-up actions in the app, and increased transparency around audit activity and user performance. Sumida reported being 100% paper free in the audit process, with “tremendous” man-hours saved and much more effective reporting and oversight.
