Nintendo EAD

Nintendo Entertainment Analysis and Development (usually abbreviated to EAD) is the largest of Nintendo's internal divisions.

In 2004, after corporate restructuring, Nintendo Research and Development teams 1 and 2 were absorbed into EAD, which now comprises at least five teams of twenty to thirty employees. You can usually tell which team developed any given game from it's director. Aside from Shigeru Miyamoto and Takashi Tezuka, each team only works on their own individual title at any given time. It is assumed further unknown teams exist, or are formed temporarily for specific individual projects. There is also a programming group of two-hundred employees within the division known as SRD.
