When Miss Maudie reflects on how the case will develop, she states the following:
"Atticus Finch won’t win, he can’t win, but he’s the only man in these parts who can keep a jury out so long in a case like that. And I thought to myself, well, we’re making a step—it’s just a babystep, but it’s a step.”
These lines help us understand what Miss Maudie believes is "progress." Miss Maudie thinks that Atticus is not going to win. However, she believes that it is possible for him to still make some progress. For Miss Maudie, progress occurs when the jury is held for longer and when cases get closer to each other, as this indicates that someday, a case like this might be won.
