The Snowflake Method is more specific, but broadly similar to those who build out plot using index cards.

As examples, see Dustin Lance Black and Benjamin Rowland.

Ben Rowland uses index cards to outline the plot of his screenplays. This is a common practice among screenwriters. Interestingly he only uses it for plot outlining and not for actual writing the way other writers like Vladimir Nabokov may have. Both Benjamin Rowland and Duston Lance Black use cards for outlining but not at the actual writing stage.
