4. Prototype Manufacture
Build a custom prototype to assure quality and full functionality; get field feedback and tweak product and/or process as necessary.
Prepare drawings, source listings, pc design documentation, parts lists, schematics, software documentation and source listings, test procedures, installation procedures and user manuals.
6. Preliminary Production
Begin low volume manufacturing (usually in quantities of 100 units) to begin product flow and to finalize details of assembly and testing prior to mass production.
