GM1 21L.A.174(b)(3);(e) Management system for design ED Decision 2023/013/R PARTNERS AND SUBCONTRACTORS Examples of elements that the process to control partners and subcontractors should normally address are: — the identification of the work to be subcontracted (e.g. design of parts, drafting drawings, stress analysis, laboratory testing); — the selection of a subcontractor based on its capability to perform the identified work (criteria (e.g. facilities, knowledge and experience) and the selection process); — the working arrangement (e.g. purchase technical specifications, statement of work); this may cover technical requirements (for parts to be design or tasks to be performed) and process requirements (e.g. procedures to be followed by the subcontractor); and — the control of the work performed by the subcontractor; this control would not only cover the deliverables provided by the partners and subcontractors but also the monitoring function required under point [21L.A.174](#_DxCrossRefBm1649097757)(c), and, if relevant, the independent function to verify the demonstration of compliance required under [21L.A.174](#_DxCrossRefBm1649097757)(b)(2). If a partner or subcontractor holds a design organisation approval (DOA), then the declared design organisation may take this into account for the effective integration of that partner or subcontractor (e.g. simplifying the selection process when the scope of work of the respective subcontractor’s DOA is similar with the scope of the subcontracted work). The declared design organisation maintains a list of all selected partners and subcontractors, including their respective scope of subcontracted work. If the independent function to verify the demonstration of compliance required under point [21L.A.174](#_DxCrossRefBm1649097757)(b)(2) is subcontracted, the declared design organisation should normally identify in its own documentation the authorised staff of the partner or subcontractor performing this function. ##### GM1 21L.A.174(b)(3);(e) Management system for design *ED Decision 2023/013/R* **PARTNERS AND SUBCONTRACTORS** Examples of elements that the process to control partners and subcontractors should normally address are: — the identification of the work to be subcontracted (e.g. design of parts, drafting drawings, stress analysis, laboratory testing); — the selection of a subcontractor based on its capability to perform the identified work (criteria (e.g. facilities, knowledge and experience) and the selection process); — the working arrangement (e.g. purchase technical specifications, statement of work); this may cover technical requirements (for parts to be design or tasks to be performed) and process requirements (e.g. procedures to be followed by the subcontractor); and — the control of the work performed by the subcontractor; this control would not only cover the deliverables provided by the partners and subcontractors but also the monitoring function required under point [21L.A.174](#_DxCrossRefBm485231253)(c), and, if relevant, the independent function to verify the demonstration of compliance required under [21L.A.174](#_DxCrossRefBm485231253)(b)(2).
