A 90% is as much an "A" as 100% (Score 1)

Remember in school you'd get the same "A" grade whether you put in a perfect 100% job or a 90% job? Sometimes coding is like this too. I work in a micro-startup (2 of us) and managed operations (read: I am coder sysadmin, etc. and tester, etc.). Given the too many things that need to be done on a daily basis, extensive testing is often just not feasible. So I shoot for 90% in my QA work and hope that it all hangs together. Most of the time that is still "good enough for government work". It's great to have teams of testers when you have resources to allocate - if I had a team to sick on this I'd do the testing in a heartbeat - but in our situation, we do what testing we can manage and move on to the next thing. If we crash (and it does happen from time to time) - we fix it quickly (grin!). One of these days we hope to be able to have more resources and I'll sing a different song. But for now we're bootstraping.
