A majority of Fianna Fáil members aged under 65 believe the party does not have a distinct identity and this contributed to the party's general election result last year.
This was one of the key findings of the party's review of recent performances in general and European elections.
It found that the identity crisis was influenced by the Confidence and Supply Agreement that pushed the party too close to the last government.
This was at a time when the report states the government was "right wing and deeply unpopular".
The review found that many voters felt Fianna Fáil had become indistinguishable from the party in government.
The financial crisis of a decade ago also marked a major shift in voting patterns.
Many party members believed, too, that Fianna Fáil was not in tune with modern social issues over the stance it took on the abortion referendum in 2018.
The party's policy was that this was a conscience vote for individual members.
Other events that members felt damaged the perception of the party included the decision to abstain on the vote of confidence in the former Minister for Housing, Planning and Local Government.
They feel this pushed Fianna Fáil closer to the government's "poor housing record and damaged the party's message".
The analysis also spoke about a long trend of leaks from the Parliamentary Party.
"These leaks are amplified in the media and are damaging to the party. This creates an impression of a fragmented party and stifles meaningful debate at parliamentary party meetings," it said.
The report states that the appointment of a director of elections on the eve of an election is not appropriate.
And it said there was no overall approval of any frontbench group of the party's election manifesto.
The review recommends that Fianna Fáil establishes a National Election Committee to ensure it is always election ready.
It also recommends that the next director of elections would not be a member of the parliamentary party and should have political knowledge coupled with experience of modern campaigning techniques.
