I am finding that this has two benefits beyond that of my writing something---anything---to keep moving forward. Having a framework at least partially done prompts me to consider how whatever scene I am currently writing will fit into the overall movement of the story and how it will move plot and characterization forward. In switching over to work on the framework, the developing scenes cause me to consider whether the framework needs revision---a character's arc and growth as explored in a scene may cause me to realize that events need to move in a different order than originally planned to best develop the overall idea and the emerging subplots.
With a half-finished framework and a bunch of undeveloped scenes, I'm still a long way from having a finished manuscript. But at least I'm enjoying myself and making progress again. Don't know if this will help the writers among you, but I hope it's at least worth considering. Happy writing!
