Optimizing Workflow with Reduction of Reworks to Models and Drawings

Abstract

This study delves into aerospace design rework challenges, focusing on Collins Aerospace. Analyzing 280 change notices, it pinpoints notes and Geometric Dimensioning and Tolerancing (GD&T) as key rework origins. Structured communication via pre- and post-task meetings, combined with training and checklists, mitigate confusion and improves attention to detail. Additionally, investing in training programs covering redlines creation and the ASME Y14.5 GD&T standard, along with providing comprehensive checklists, proved instrumental in enhancing the accuracy and completeness of design submissions, ultimately resulting for the reduction of reworks instances. Key Terms ⎯ Change Notice, Product Lifecycle Management, Redlines, Geometric Dimensioning and Tolerancing.
