St Kilda have roped in ex-North Melbourne coach David Noble to help determine why the Saints faded so badly to miss finals football.
Club president Andrew Bassat is leading an extensive review with the working party also including new board member Jason Blake and incoming CEO Simon Lethlean.
Noble was sacked by North Melbourne after round 17 this year but has spent time in the football department at Brisbane and Adelaide.
The Saints also announced on Thursday they are undertaking an external assessment of the club's list.
Bassat acknowledged it was a frustrating season and said they would scrutinise the erratic form of the team, who are 10th heading into the final round.
St Kilda started the season with eight wins from their first 11 matches, but faded after the mid-season bye to record 11 wins from 21 games.
He said the board would also be put under the microscope.
"Last month I initiated a comprehensive review of all aspects of our club that relate to on-field success," Bassat said in a statement.
"This year, in the context of the head of our football program transitioning to CEO and the disappointment of the second half of the season, we are undertaking a much more extensive process.
"We have been asking ourselves all the questions our members would expect of us, and we are scrutinising the key underlying factors contributing to our inconsistency and a host of other aspects which roll up to ultimately reflect in the performance of our team week to week."
