Jeff >I misquoted the units for code development. Industry standard figures >are 10 SLOC/person-day (not per person-hour). Doubling this gives 7000 >person-days (not person-hours). Luckily, I was thinking person-days even >as I typed person-hours, so the figure of "about 30 person-years" is >still correct. I didn't want to mention it, but seeing as you brough it up, I imagine this quote from your original message is also a typo: >A more realistic estimate, using 10 kSLOC/day and 5 errors/kSLOC, is $1.8M over >6 years to increase the number of errors by at least a factor of 10. I can't say I know of anyone who has ever written 10kSLOC/day :-) Apart from that, it was certainly a well presented argument in favour of retaining Ada. John
