You are planning to outsource your pattern production?
All the more important to have well-documented basic patterns!
With well-documented basic patterns you support production in “full package business” (purchase of finished clothes). Documentation guarantees high quality standards, it avoids nasty surprises and helps you to obtain styles which meet your company’s requirements.
Additionally, companies rarely document their pattern know-how. The expertise is in the minds of their employees and is passed on to new employees over the years. Each time an employee leaves, the company loses expertise. You can secure and stabilize internal knowledge and even extend it by documenting your know-how.
