When I was working at the Boeing Company in the mid-1980s, one project with about 80 programmers was at risk of missing a critical deadline. The project was critical to Boeing, and so they moved most of the 80 people off that project and brought in one guy who finished all the coding and delivered the software on time. I didn’t work on that project, and I didn’t know the guy, but I heard the story from someone I trusted, and it struck me as credible.
