    CAD tools such as SolidWorks can be used in such ways that mistakes can result. Dimensioning errors and stackup, missing dimensions and BOM errors are possible. Does anyone know of any LSS Projects aimed at improving CAD?

    @calespy – We published an article about poka-yoke with CAD last year – How to Poka-yoke CAD Drawings, https://www.isixsigma.com/tools-templates/poka-yoke/how-to-poka-yoke-cad-drawings/.

    @calespy – The article that Katie suggested is a good start. A full answer depends on what you are finding as the primary failure mode(s). Do you need operator training, operator discipline (older draftsmen have a bad habit of overriding the CAD data, ’cause that’s what they used to do on velum), or do you have titleblock data inconsistencies, etc.? Each of those may require a seperate and unique approach to solve the issue.

    Thanks Katie and MBBinWI for responding to my question. We see an array of defects coming out of our CAD System. I am sure that additional training and discipline would help but I favor a more robust process. There are CAD Systems that are said to be “Correct By Construction”. They leave little room for user errors. I am interested in what others have done to make their CAD Process more robust.
