Duncan Fletcher says he will review his position as England coach before the start of the next domestic season.
Fletcher has been criticised for his role in the Ashes defeat
The England and Wales Cricket Board has said it will review Fletcher's position after the World Cup in April.
"I'll just make up my own mind," Fletcher told reporters on Tuesday. "It might be a move in six months. But I'll make up my mind.
"I'll have a look at where I've been and where I want to go and I'll continue in that way."
England chairman of selectors David Graveney was in defiant mood despite the crushing surrender of the Ashes in the third match of the series at Perth.
"I'm very happy with the process we have at the present stage," he told BBC Radio Four's Today programme.
"One thing we probably need to look at is what happens away from home."
On Fletcher's future he said: "He's an outstanding coach, less than a year ago he was receiving multiple awards but like everyone he has a shelf-life."
What Duncan has done for English cricket has been magnificent
Graveney also rejected any idea he would step down after a decade in the post.
"No thoughts of resignation. What happens in the future is not necessarily down to me it is down to others but I love doing the job," he said.
Fletcher has been at the helm of the team since 1999 and has a rolling contract with the ECB.
He has come in for heavy criticism of his part in the Ashes defeat.
Former England fast bowler Darren Gough backed Fletcher to stay in charge, telling BBC Five Live: "Duncan has been a superb coach and he still has got a lot to give English cricket.
"But at some stage we are going to have to go and look around and see who we can get to take over."
"What Duncan has done for English cricket has been magnificent."
Earlier ECB chief executive David Collier told BBC Sport: "After the World Cup we will truly reflect on where we go."
But ECB chairman David Morgan described Fletcher as a "hugely successful coach" and made it made it clear he had "full confidence" in him.
England relinquished the Ashes by completing their third defeat in three matches in Australia on Monday, but the Boxing Day and New Year Tests in Melbourne and Sydney represent an opportunity to rebuild confidence.
"I believe Duncan Fletcher is the best person to analyse the problem and come up with solutions," said Morgan, who previously worked with Fletcher for county side Glamorgan.
Both he and Collier dismissed the suggestion that England had been under-prepared for the series.
"I think it's quite important you have to get the balance right between preparation and the players having a rest period," Collier commented.
"The England management all believe the preparation was right.
"Ideally, we'd like to have slightly longer, but the way the calendar worked meant that was impossible."
