Germany, who were expected to reach the latter stages of Qatar 2022, crashed out at the group stage, leading to the departure of team director Oliver Bierhoff after 18 years.
There was speculation boss Hansi Flick would follow him, but the former Bayern Munich coach confirmed he would be staying on board.
The new advisory group includes former Bayern CEO Karl-Heinz Rummenigge, Oliver Mintzlaff, and former Germany internationals Matthias Sammer, Rudi Voller and Oliver Kahn.
It will be led by Neuendorf and DFB vice-chairman Hans-Joachim Watzke.
"I think this is a group that knows a lot about men's football and the national team," Neuendorf said. "We are not an association in which one person decides everything.
"There will be a first discussion before Christmas. We will give ourselves a timetable there. We have to join forces towards the European Championship in 2024. It has to be a success."
Neuendorf also confirmed there will be a new group that will "take a close look at the entire business area for which Bierhoff was responsible".
This group will include DFB general secretary Heike Ullrich, former Germany international Philipp Lahm and European Championship ambassador Celia Sasic.
"We will see how we set up the area in the future in order to be successful," Neuendorf added. "And we will be self-critical."

Martinez came off the bench in extra time of Thursday's Super Cup against Sevilla in Budapest and five minutes later he headed in the winner in a 2-1 victory that earned Flick's treble-winning side yet more silverware.
It was Martinez's first goal since April 2019 and it may be the last of his eight-year Bayern career as rumours of a return to LaLiga outfit Athletic persist.
The 32-year-old is in the final year of his Bayern deal, and reports suggest the Bundesliga and Champions League holders want a transfer fee for the midfielder despite Athletic's wish to bring him back to Spain on a free transfer.
"Javi scored the goal and won us the game. Sometimes football writes these stories – this is a beautiful one," head coach Flick told Sky.
"On Wednesday there were reports that he was in Bilbao, yet tonight he scored the winning goal."
Martinez also came off the bench to score an extra-time goal in Bayern's previous Super Cup triumph seven years earlier, when they beat Chelsea on penalties.
This time they triumphed inside 120 minutes, having fallen behind to Lucas Ocampos' penalty before Leon Goretzka levelled prior to half-time.
It may not have been as comprehensive as their season-opening 8-0 win over Schalke in the Bundesliga last week, but Flick was nevertheless pleased with his team's staying power.
"It took the first 15 minutes for us to get into the game," Flick said.
"It was great for me to see the team try to pull through with their mentality – and succeed. In the end, my players went through the pain barrier to win."
Germany crashed out of the World Cup at the group stage, which led to team director Oliver Bierhoff leaving his role.
There was speculation boss Hansi Flick would follow him, but the former Bayern Munich coach has confirmed he will be staying on board.
Vogts, who led Germany between 1990 and 1998, believes the German Football Association (DFB) has paid the price for fostering a harmonious atmosphere and wants Matthias Sammer appointed to ruffle some feathers.
"I was surprised that Oliver Bierhoff went so quickly," he wrote in the Rheinische Post. "But it speaks for his character that he is retiring and thus taking responsibility after the second preliminary round exit at a World Cup in a row.
"But the problems of German football are not solved with the departure of Bierhoff alone. There are too many theorists at the DFB who are far removed from football. You have to be close to the game again; in player training, but also in coaching.
"I hope that Matthias Sammer will work in the background and support Hans-Joachim Watzke [vice-chairman].
"Matthias is a child of football, he knows and loves it, and he is a critical spirit who also addresses unpleasant things.
"That was missing in the DFB for too long. That's certainly something that Oliver Bierhoff has been accused of. I often pointed this out to him, but criticism was not welcome in his environment.
"That's why I left the DFB advisory board years ago. I hope Watzke will re-establish a healthy culture of debate in the DFB with Sammer in the background.
"There has been too much harmony in the DFB in recent years. This has led to a standstill in many places. Hansi Flick will also benefit from more friction in his work.
"It's right to leave him in office. It's not just with a view to the European Championship, but he has the full confidence of the DFB to put our football back on the road to success."
Bayern were rumoured to be in the running for the Germany international, but it has been reported that Chelsea have triggered his £54million (€60m) release clause.
Werner has played a direct part in 32 Bundesliga goals this term - second only to Borussia Dortmund star Jadon Sancho - and Flick acknowledges the Premier League side have pulled off a big signing.
"He is a very good player, a player who scores goals," Flick said at his pre-match news conference ahead of Saturday's league clash with Bayer Leverkusen.
"This is Timo's decision and you have to respect it. If what's being reported is true, then Chelsea have made a very good signing."
As well as being linked with Werner, Bayern have also been tipped to sign one of Leroy Sane or Kai Havertz when the transfer window opens.
Havertz last week became the first player in Bundesliga history to reach 35 goals before the age of 21 with his strike against Freiburg, and Flick admits he would like to have the "exceptional" forward at Bayern.
"I think there aren't too many coaches who would mind having Kai Havertz in their team. Me included," he said ahead of Bayern's trip to BayArena.
"I've known Kai for a long time, since I accompanied Germany during the Under-17s European Championship in Azerbaijan. Even then he showed how good of a player he was.
"There were two or three really good players and he is the one who developed the most since then for sure.
"Kai is player who moves between the lines very intelligently and has got a good speed. He is very calm with the ball and we saw that against Freiburg.
"He's got that goal instinct and is able to put the ball through the smallest gaps at his young age. This is exceptional. Obviously it's nice to have players in your team who score."
