I'm more like Claes, but did everything in Filemaker.
It started back in 1992 and evolved together with each version of FM.
I now rebuild from scratch in version 7/8, where the beginning was in FM 3.
Due the complete relational development I have now a huge library from all the audits with all the items, from each single customer.
I could never find a commercial product that did exactly what I needed, nothing more, nothing less, hence the own development.
And I'm very happy with it, upload all the needed data for a customer/audit in my laptop, and ready to go...excange info with other auditors, no problem.
Although I don't use checklists anymore, comes with the years I think, the written down info is scanned and imported into the database...nice and easy...
Funny thing is, I got calls from customers for information they know I can retrieve very quick...gives me an item to check at the next audit...
