A failure is a failure, but it can also be a learning experience. I was once forced into a failure because despite my protests my employer sold a solution that was no longer vendor supported. The sales person didn't want to hear it, the business owner didn't want to hear it. They just wanted to make the sale. By the time I spent months trying to fix what couldn't be fixed the former marine business owner gave me some "come back with your shield or on it" speech to go out and fix the problem or else. I tried to fix the problem but couldn't and chose or else, i.e. I quit. I learned to document everything in writing so that I have a paper trail for later. Fortunately it didn't come to a lawsuit from the unhappy customer but it got close. Having everything documented so it was 100% clear I never wanted to sell the system and spent scads of time trying to fix it anyway, not to mention communication from the vendor saying "It work won't and we told you it won't work" would have made life much easier for me if it came to discovery.
