Alastair Cook's men have been outplayed in every department in what is turning out to be a nightmare tour to Australia, who ended a run of three consecutive series defeats against England by taking an unassailable 3-0 lead in Perth on Tuesday.
With Tests in Melbourne and Sydney to follow, there is cause for concern that the tourists are heading for a 5-0 whitewash defeat.
Boycott told BBC Radio 5 Live: "The planning and the prep of the team - it's all gone haywire. In all areas they have been better than us.
"They have had good plans and executed them really well while we've cocked it up big time."
Boycott was particularly critical of England's coaching staff and has demanded team director Andy Flower leave his position if he is not up to the challenge of leading the side any more.
"Some of our coaching staff should have a serious look at themselves because we are on the down and Australia are on the up," added Boycott, who scored 8114 runs in 108 Tests for England.
"We should be thinking and planning for 2015. Is our coach up to it?
"The top people have to decide - Andy Flower, are you going to be here next year? Are you staying or going? If you've had enough, go now.
"We have to be up for the challenge - we have to have the balls to do something."
