General Manager Kenny Williams was careful not to compare Ventura's duties with those of former longtime Manager Ozzie Guillen, who was released from his contract after eight years and a World Championship at the helm.
Guillen has since been hired as the new skipper of the Florida Marlins.
Williams said Ventura's involvement in many phases of the team would be an "all-inclusive style of management," the Chicago Tribune reported.
"Robin will be very involved in every aspect, whether it be player development and off-season conversation with the players, the coaches, the scouts, everything," he said. "That's just baseball and the way we like to do things."
Ventura said he was ready to hit the ground running because, as a 10-year player for the team in the 1990s, he already knows many on the current squad.
"Fortunately, I've been around enough to have a relationship and talk to guys and know who they are, and the rest of that is going to happen in spring, just watching these guys," he told reporters.
