"Scandal" will officially end after Season 7.
"She has had, for a while, a sense of how she wanted the story to end," Dungey said, according to Entertainment Weekly.
"She said, 'Look, I really feel like Season 7 is where I want to wrap up this story, because I always prefer to end a show where you're feeling on top as opposed to letting things fizzle out.'"
The Hollywood Reporter reported the popular political drama has yet to set an episode count for Season 7, although the season is expected to again feature "a short number of episodes."
"I do think that audiences, especially fans and Gladiators, who are as loyal to Scandal as they've been, are going to want the story to end in the way that Shonda intended to," Dungey said.
"That was a decision she felt really good about and we support wholeheartedly."
The producer told Entertainment Weekly at the show's 100th episode party in April that she had an end point in sight.
"I know how long the show is going to run, and I know how it's going to end, and I'm excited about it," she said.
"Scandal" stars Washington as crisis manager Olivia Pope, with Scott Foley as NSA Director Jake Ballard, Tony Goldwyn as President Fitzgerald Grant and Bellamy Young as Senator Melody Grant.
