In a retrospective review for AllMusic, Donald A. Guarisco gave the album a mixed 2.5 stars out a possible 5. He wrote, "Anyone who thinks of this family group as a bubblegum soul outfit will be bowled over by this incredibly ambitious outing, which attempts to explain the family's Mormon beliefs through a series of songs that cut across a wide variety of pop genres." The Osmonds proved themselves versatile at tackling a variety of musical styles, according to Guarisco, but the album was ultimately a "misfire" because the creative diversity led to a lack of cohesion for The Plan as a whole.
To commemorate the album's release, the band produced a 10-minute music video, performing a medley of the selected songs in the following order: "Traffic in My Mind", "Let Me In", "Are You Up There?", "The Last Days", "One Way Ticket to Anywhere", and "Goin' Home". This medley was performed live, and during Wayne's flute solo intro to "Let Me In", Alan announced the recent release of "The Plan".
