Overview and Outcomes.
Overview
How you frame a problem decides which solutions you can see. This module covers two simple root cause techniques from the Toyota Production System tradition: the five whys, associated with Taiichi Ohno, which follows one chain of reasoning in depth, and Ishikawa's fishbone diagram, which widens the search across fixed categories first. It shows how to run both well in a meeting, how they fit together, and why the discipline matters more than the technique. This deliberately narrow module asks whether a decision is genuinely made with the people it affects, or made for them and then announced. It sets out a collaboration spectrum from competing to co-designing, separates coordinating from collaborating, and adapts Habermas's principles of communicative rationality into three tests of comprehensibility, sincerity and legitimacy. Porto Alegre's participatory budgeting shows what binding citizen authority, combined with technical scrutiny, can look like.
What you'll develop
In this Bitesize, you will develop the ability to:
- Apply the five whys to a recurring problem, continuing until the answer would genuinely prevent recurrence.
- Identify the three ways a chain of whys breaks down, including stopping at a person rather than a process.
- Use a fishbone diagram with a group, and combine it with the five whys by working breadth first, then depth.
- Distinguish a decision made with people from one made for them, and between gathering opinions and sharing the decision.
- Use the collaboration spectrum to name honestly where a relationship sits, including the difference between coordinating and collaborating.
