  • ® © 2003–2012 Mountain Goat Software®Source: “How Apple Does It,” Time Magazine,October 24, 2005 by Lev Grossman“Apple employees talk incessantly about whatthey call ‘deep collaboration’ or ‘cross-pollination’ or ‘concurrent engineering.’“Essentially it means that products don’t passfrom team to team.
