The birth of the Federation was first hinted at during part two of "Shockwave", which opened the second season.  When Manny Coto was made show runner for the fourth season, he decided that the focus of the series should be to link to that event. With this in mind, his intention was for this season to move towards that goal.  Judith and Garfield Reeves-Stevens were hired as writers on Enterprise because they wrote the non-canon novel Federation and after it was suggested by producer Mike Sussman .  The episodes for the fourth season were intended to lay the framework for the later creation of the Federation.  This was something that the cast said that they would have liked to see more of, with Scott Bakula later saying "I would have loved to have been able to explore that journey to the Federation and their creation of it ... to a greater extent. And I think that would have been, um, just more fun for the audience ... just better, longer storytelling."
