	'''OSE Kit Certification''' is a certification for producing OSE kits as an independent, certified producer. A certification is required for each specific product that OSE designs and builds - it is not a blanket certification for all OSE products.

	As a deeper evaluation of the kit - OSE staff will build the kit to document that an efficient build is possible - proving kit completeness and adequate part quality. Any new observations regarding kit quality will be made at this time. The build by OSE staff constitutes a definitive verification of kit quality - as verified by the simple fact that a successful build can be performed by trained OSE staff. There are 2 requirements for a perfect score on the kit: no defects, no incompletely prepared parts, no rework needed on incorrectly-prepared parts, and no missing parts.

	The certification is a quantification of competency for future improvement. The intent is to improve on the score with time. The minimum baseline is 4 hours for a single kit, and 2 hours each when doing 4 kits at one time. An experienced kit builder should be able to produce 12 kits to spec in an 8 hour day.		The certification is a quantification of competency for producing 3D printers, and is intended for future improvement of one's 3D printer building competency. The intent is to improve on the score with time. The minimum baseline is 4 hours for a single kit, and 2 hours each when doing 4 kits at one time. An experienced kit builder should be able to produce 12 kits to spec in an 8 hour day.

	The kit build is evaluated based on the pictures and data submitted. One kit shall be shipped to OSE headquarters for further evaluation. Further evaluation involves more detailed quality control of parts - on top of the pictures and data already submitted. Attention will be paid to kit completeness and quality of parts. Perfect results mean that there are no missing parts, no defects in parts, and no additional work or rework is needed on any of the parts in order to perform a successful build.

	The kit is desiged such that a complete machine can be built from a prepared kit in 5 hours. Kits can be prepared such that it takes either more - or less - effort than the 5 hours - but the 5 hours is chosen so that it is practical to run [[One Day]] workshops with it. ~~tIn~~ order to achieve such a build time, the kit must be in a ~~suffcient~~ state of completion that allows a 5 hour build. The ~~tradeoff~~ for the kit is the level of completion: the easier the kit is to build and the less time it takes - the more time it will take to prepare the kit. The time to prepare a kit should be no more than 2 hours based on the simplicity of the OSE design - and that is starting from off-the-shelf parts.		The kit is desiged such that a complete machine can be built from a prepared kit in 5 hours, and 6 hours until a successful benchmark print of [[3D Benchy]]. The 6 hour benchmark includes cleanup of all wiring such that the printer is production-ready for doing long, demanding prints.
