Lateral thinking – breaking out of the habitual patterns of linear thought, changing the direction of thinking, looking at things in totally different way or reinterpreting what you are looking at in fresh, original or humorous ways
Parallel thinking - contrasts with traditional adversorial thinking styles where two factions argue over opposing ideas. Parallel thinking yokes opposites viewpoints and gets them to think in tandem towards a common aim, noting down the parallel track of thinking and any opposing views that may be expressed, but proceeding towards the common aim and using the dialogue and thinking process to design a mutually acceptable result
