Research shows that team productivity is actually bounded not by how efficiently individual developers work but by communication and coordination overhead [5]. This is partly because teams work only as fast as decisions can be made, and many of the most important decisions are not made individually but collaboratively. However, this is also because even for individual decisions, developers often need information from teammates, which studies have shown is always one or two orders of magnitude slower to obtain than referencing documentation, logs, or other automatically retrievable content
