I swear by outlining . . . but wow, once I put in word constraints (ie 110,000 words for the entire novel) it gets frustrating to keep within it. It does force me to stay focussed on moving forward though - you can block each 'section' into percentages and get your maximum word count from there to ensure the novel is 'moving'. I give myself a break though - I make sure I give myself a day a week to just write anything within the novel and ignore the 'rules' ( a lot more fun!).
It's worth investigating.
