GM1 21L.A.122(a);(b) Eligibility ED Decision 2023/013/R INTERFACE BETWEEN DESIGN AND PRODUCTION In the natural or legal person that declares the production capability there is a need for an interface between staff responsible for design and staff responsible for production. This interface may be achieved through common design and production procedures. Other ways to document this interface may be also used. For example, by defining simple flow charts supported by self‑explanatory forms, or by task descriptions of the responsible functions in the organisation. IT-based enterprise resource planning (ERP) systems may be used to ensure and to demonstrate that there is a correct flow of information on the basis of defined and visible workflows with assigned roles and release gates. Such interface normally covers the following aspects: — the transfer of applicable design data from design to production (including their status: approved / non-approved); — the development of own manufacturing data; — the management of continued airworthiness matters and required actions; — the cooperation in compliance-demonstration activities (e.g. manufacturing and testing prototype models and test specimens); — the management of production deviations and non-conforming parts; and — the configuration control of manufactured parts. ##### GM1 21L.A.122(a);(b) Eligibility *ED Decision 2023/013/R* **INTERFACE BETWEEN DESIGN AND PRODUCTION** In the natural or legal person that declares the production capability there is a need for an interface between staff responsible for design and staff responsible for production.
