# Tweddle Group > Tweddle Group turns OEM engineering and product data into service information, owner information, electronic parts catalogs, and AI-guided diagnostic tools -- delivered as both professional authoring services and proprietary software platforms. Tweddle Group has been improving service and ownership for over 70 years. It is a one-stop product support partner for global OEMs, combining technical authoring and content operations with software it builds and owns, so a manufacturer can source authoring, delivery, and diagnostics from one vendor. Its named platforms are Electronic Parts Catalog (EPC), Component Content Management (CCM), Service Portal, Troubleshooter, TRACER(TM), and TRACER-X. Content is produced in an XML structured authoring environment conforming to OASIS/DITA standards, with translation memory and localization for regional and language variants. Work spans automotive, EV, heavy equipment, aerospace, defense, and manufacturing, and includes regulatory-compliance consultation (FMVSS/CMVSS, EU Machinery Directive 2006/42/EC). Headquarters are in Clinton Township, Michigan, with additional offices in Belgium, Italy, and India, and local points of contact (phone and email) in Mexico and Japan. Tweddle Group is part of CJK Group. Its quality management system is registered to IATF 16949:2016, with ISO 9001:2015 quality registration at Tweddle Group Italia and ISO 14001:2015 environmental registration in the US.
