Eastwood joined the Warriors board this year and has a background in high performance culture having previously worked with English Premier League teams Chelsea and Manchester City and also South African cricket and English rugby.
"We'll use his expertise over the next two or three weeks and have a look all across the organisation at what we need to do to get that winning culture and get success," explained Doyle.
"We've got to look at what needs to improve and make the decisions that are necessary.
"We'll interview players starting this week and talk to all of the coaching staff and strength and conditioning staff, mental skills people, and we'll get individual reports."
Of chief concern to Doyle was the club's recent history of slow season starts with an average of just three wins from the first eight rounds.
As happened this year, the club tends to enjoy an upward swing in form to achieve better results in the middle eight rounds of the season but the closing block of eight games have proven just as difficult as the first.
Doyle said the aim was to ensure the side begins next year's campaign better to ensure they are not put under undue stress as the regular season draws to a close.
"It puts us all under lots of pressure," he said.
"We went well through the middle and then fell off again at the end winning two games of the last eight, and again hence why we didn't make the eight.
"We've already started talking and we have a significant focus on next year to look at how we can start the season off well and win more than three games out of eight.
"We've got to get ourselves into a position where we start the season well so that we are not desperately relying on the end on winning those last couple of games to get ourselves into the finals."
