The West Indies sacked controversial coach Richard Pybus amid a flurry of changes announced on Thursday, only seven weeks before the start of the World Cup.
Floyd Reifer will become interim head coach, with Robert Haynes replacing Courtney Browne as interim head of selectors, while the entire selection panel has also been changed.
"We are confident that in Mr Haynes we have found an interim chairman who shares the philosophy of inclusiveness and shares our selection policy," Cricket West Indies (CWI) president Ricky Skerritt said.
The appointment of Englishman Pybus had been met with criticism, including from former captain Darren Sammy, who blamed him for causing the West Indies squad to strike on the 2016 India tour while the director of cricket.
The change of coach could potentially pave the way for star players to return to the team, with the likes of Dwayne Bravo and Kieron Pollard playing almost exclusively franchise Twenty20 cricket, with Andre Russell also having not played an ODI since last July.
