The open systems interconnection (osi) reference model first came into being in 1978 the osi group was intent on getting a model into the field quickly, so they elected to adopt a seven-layer model created by charles bachman of honeywell by this time, the lower four levels of the model had already been well established, [. The origins of osi william stallings the history of the development of the osi model is, for some reason, a little-known story much of the work on the design of osi was actually done by a group at honeywell information systems, headed by mike canepa, with charlie bachman as the principal technical member.
