Sam Michael could be the victim of moves to restructure Williams, following a bad start to 2011 for the famous British team.
The FW33 was not quick or reliable in Melbourne and Sepang recently, moving chairman Adam Parr to announce a process to improve Oxfordshire-based Williams.
"We will be looking not only at how to address the short-term issues, we will be working together to strengthen the team for 2012 and beyond," he said.
"Every aspect will be reviewed, nothing is sacred, but we will do this methodically and not in a reactive way," added Parr.
Reports in Germany suggest that Williams' current technical director Michael, an Australian, could be at the top of the list.
Motorsport-total.com said team shareholder Christian 'Toto' Wolff - usually a behind-the-scenes influence - will attend the Chinese Grand Prix this weekend as Williams looks to restructure.

He said there are "five or six core issues" that need to be addressed, including "the human factor" and that fact that the move "from the founding generation to the next" has not been smooth.
It is believed Wolff's comments are a reference to Michael, who took over in charge of Williams' technical operations from team co-founder Patrick Head in 2004.
