Warwickshire's director of cricket Dougie Brown is to leave the club by mutual consent.
Former international all-rounder Brown, who has spent his entire professional career on and off the pitch at Edgbaston, says the club is not where it "should be".
The club won last month's Royal London Cup final at Lord's. But it only narrowly avoided relegation from Division One of the Specsavers County Championship, and did not qualify for the NatWest Blast quarter-finals.
Dougie Brown said:
The club has a very proud history of challenging for silverware - and despite winning the Royal London Cup this season, failure to qualify for the NatWest Blast quarter-finals and narrowly avoiding relegation from Division One of the Specsavers County Championship on the last day of the season is not where (we) should be.
