A development of Morphological Analysis (a.k.a. Attribute Listing). Imagine Rubik’s Cube or a fruit machine. Each of the three axes of the cube, or reels of the slot machine, represent a key variable such as:

  • manufacturing process (reel 1),
  • packaging (reel 2) and
  • target market (reel 3).

Pull the lever of the slot machine to start the reels spinning, and see what combination appears, such as extruded material in a tube for pregnant women.
