I am currently attempting to formulate a plan/procedure/convention/ whatever you want to label it, to initially document and then track changes to custom built machines that we receive in from outside vendors. The main challenge at hand is how to handle the vendors' information (e.g. CAD, electronic docs, BOM, etc.) in regard to inputing the information into our system (Windchill). The next challenge is how to track any updates/changes beyond the initial receipt of the machines and associated information. I would like to hear from anyone who has a similar situation and how they have handled things. TIA - Tim
