W-type problem-solving model

• By Jiro Kawakita of KJ method.

• We need empirical science before outdoor science.” - Before the phase of “experimental science” in which trial and error is repeated, a phase is necessary to generate the first “hypothesis”. Jiro Kawakita called this phase “field science. The field science phase consists of “exploration”, “observation”, and “idea”.

  • The level of thinking and experience level correspond to the bottom and top of my pyramid model.
    • What is the bottom in the pyramid metaphor?

I gave a lecture titled “W-type Problem Solving Model of KJ Method and U-Theory, and their respective problem consciousness”. - NISHIO Hirokazu’s Hatena Diary

The other day, I gave a lecture on what U-theory is at the Software Engineering Technical Committee of the Japan Electronics and Information Technology Industries Association (JEITA). In explaining the U-shaped model of U Theory, this slide explains “what other models exist in the first place” and “what is similar and what is different”, so you can understand how the PDCA cycle, Lean startup, KJ method, etc. and U Theory are similar and how they are different. I think you will be able to understand how U-theory is similar to and different from PDCA cycle, Lean startup, KJ method, etc. from various aspects. 「 W-type problem-solving model of the KJ method and U-theory, respectively 」
