> A thousand man-years of effort? Sounds like a very large project. Kind of. It's upper-medium. It's nothing compared to Microsoft Office, a web browser, etc. Microsoft for example has maybe 50k developers and so creates 50,000 man years of work every single year. > Typical project size is somewhere around 500 to 1000 man days. That's roughly 2 devs for a year. That's hardly even a prototype where I work. It is fascinating to see the difference in scale in our industry.
