The series was created by Dick Blasucci, Marc Flanagan, and
Sam Simon. Blasucci also served as executive producer of the series, alongside
Emmy Award-winner
James L. Brooks and
Danny Kallis, who previously worked alongside Judith Light as a writer/producer on ''Who's the Boss?'' Despite being one of the show's main stars, William Devane did not receive on-screen credit in any of the episodes. Devane was originally slated to get second billing in the cast, between Judith Light and Angela Goethals. He reportedly fought to have top billing, or at least shared top billing with Light, in response to his
Knots Landing fame. Both the producers and ABC refused to move Devane's billing, believing that Judith Light having sole first billing would draw in more of the female 18-49 demographic that is attractive to advertisers and would bring back ABC viewers who had made Light's previous series, ''
Who's the Boss?'', a success. Devane ultimately told the producers that if he couldn't get a billing change, he would rather not be credited at all.
Phenom's theme song, "The Promise and the Prize," was written and performed by
