I've used quadrant exercises in marketing work. I really like how structuring the exercise as you show here takes such a deep dive into thinking through a brand identity. Defining more specific quadrants for a client can be productive too, like how low tech or high tech do you want to be seen? One thing I've seen a lot is clients struggle identifying post-it notes and quadrant location. Another thing is clients leapfrogging the exercise and going straight to creative ideation (usually a big mistake). You communicate the quadrant process, meaning and value very well!
