Robin Dargue will leave his position as CIO at the drinks giant, which he took on in 2003, and will start his new role at Royal Mail, a Diageo spokeswoman confirmed. No replacement has been announced yet.
Royal Mail confirmed that Dargue will start by the end of October. Dargue had previously worked at Mars and Logica Financial Systems, before becoming IS director at UDV, which became part of Guinness and then part of Diageo.
Dargue successfully oversaw the deployment of a global enterprise resource planning (ERP) system to support Diageo's core back-office processes.
Speaking at a Forrester event earlier in the year, Dargue said that the role of the CIO was changing, moving from just managing technology, to managing the delivery of business results through innovation, as IT becomes more involved with the way companies work.
"The conversation CIOs will now be having with CEOs will centre around what functions IT could be performing to help the business grow and differentiate themselves in the market," he said.
