Scenes and conflict - in need of expert revision advice

I'm currently working on revising a novel and find myself in uncharted territory. I've never made it this far! Now I'm scratching my head as I sit with my scenes in front of me.

Does every scene need to further complicate the main conflict of the story? Or can scenes exist that achieve character development but not so much conflict development?

Anyone have thoughts out there for analyzing the effectiveness of scenes?
