Wrote detailed work instructions, including pass/fail quality checks.
Assembled the product for the first time to make sure the build matched the engineering intent.
Results
Better communication and organization around the build.
To add: what the instructions replaced, what the first build taught you (parts that did not fit, steps in the wrong order), how the instructions changed because of it, and any numbers such as build time or steps.
