2. DO WE STILL NEED TO CARE ABOUT QUALITY?

3. on average professional coders make 100 to 150 errors in every 1000 lines of code they write defects found in production cost 10x more to fix than those found during requirements gathering last year, canceled projects cost firms $67 billion; overruns on the other projects racked up another $21billion software bugs cost the us economy an estimated $59.5 billion every year

4. need something a little more concrete?

5. USS YORKTOWN, SMARTSHIP crew member entered 0 in a data entry field, caused a “divide by 0” error that shut down propulsion ship was dead in the water for 2hrs 45mins

6. ARIANE 5 FLIGHT 501 re-used code from ariane 4, but took a different flight path because of different booster design conversion from 64bit float to 16bit signed int caused overflow (exception handler was disabled for perf reasons) cost: > $370 million @ 1996 prices

7. F-22 RAPTOR deploying overseas to japan the first time crossed international dateline Raptor is likely the most advanced manned aircraft that will ever fly… computers crashed losing all navigation and communications systems clear weather allowed them to follow tankers back to hawaii

8. need something a little more visual?

21. “…the real low-hanging fruit is often not automating some test execution but automating other testing tasks, like populating databases or automatic navigation to the page where you’ll start manual testing. you’re not reducing the number of manual tests, but you’re reducing the total time it takes to run them...” - mike cohn quoting brian marick
