Ugh! I still have nightmares about having to write the Validation procedure documents for a medical device production Quality system written in VBA/Excel. The program had started out as some scientist's desktop tool and somehow over the years, morphed into an actual production tool that now needed to be formally validated since we needed to make a change to it. Worst combination of spaghetti code and Big Ball of Mud that I've ever seen. I had the misfortune of being the only SW dev who was senior enough to do the task and who wasn't busy at the time, so I drew short straw! I shudder to think of the millions of dollars of product that have been shipped as a result of that code!
