Yorkshire could delay unveiling their new coaching set-up until mid-November.
Yorkshire's players have had little to cheer in recent seasons
Dermot Reeve, currently in Australia, had been hoping to sign a deal to head up the new team, possibly as cricket director, before he flew out on Sunday.
No contract was agreed on, though Yorkshire chief executive Colin Graves says Reeve is still in the frame.
Graves told this website: "We are talking to a lot of people at the present time. It will be up to six weeks before we settle on anything."
"By that time we will know what we are going to do and how we are going to go about.
"We are going to revamp and change everything but we are not rushing into anything here."
Graves took over as Yorkshire boss in the middle of the 2002 season in which they were relegated from division one of the County Championship a year after winning it.
During the season just finished they were also relegated from division one of the National League and failed to win promotion in the Championship.
Graves said: "We are looking at re-structuring the whole of the coaching management.
"The cricket side is staid - it needs changing - it hasn't worked been worked on or improved on for a while."
