Glamorgan have confirmed a single head coach will lead the county across all formats next year.
The role was split in 2023 as Matthew Maynard led the championship team and Mark Alleyne in charge of shorter formats.
Maynard has stepped down, along with chief executive Hugh Morris following a disappointing season at Sophia Gardens.
Director of cricket Mark Wallace said they will revert to a "traditional" structure following a review.
"There were some positive elements with the split coaching model and both Matthew and Mark embraced it and managed their areas well," he said.
"However, with the hectic nature of the schedule and the need for players to switch across formats, we've decided to move back to a more traditional structure moving forward."
Wallace is now leading the search for a new head coach while Alleyne will remain as part of the coaching staff.
It follows a tumultuous year in which Glamorgan again missed out on promotion again from Division Two of the County Championship and failed to reach the knockout stages of both the One-Day Cup and T20 Blast.
That led ex-wicketkeeper Tom Cullen to claim "cronyism" had held back Glamorgan given the Welsh county's policy of appointing former players - such as head coach Maynard, Wallace and Morris - to management positions.
Ex-England fast bowler Simon Jones has also said "big changes are needed as quickly as possible" to get the county back on track.
However Michael Hogan, who retired last month having spent a decade at Glamorgan, disagreed and claimed the environment in his last three years in Wales were the best he had seen.
