Rust

Homework Case: Detected increase in incidence of rust afflicting either or both the vehicles produced by our automotive brand name. Said increase is defined as that which occurs before the guarantee period against rust expires, but also the period shortly after the expiry of the guarantee date. The term shortly after is given an arbitrary value of 18 months.

Solution pathway:  1- You need to name your result or effect, the fish head, correctly. 2- Consider using the manufacturing categories (Slide 16) in Ishikawa Diagrams as a start.

You may also choose your own categories if applicable, or you can augment the manufacturing categories with your own categories. 3- You determine your own categories as a result of affinity analysis and brainstorming sessions (Slides 18-20). 4- Come up with the possible categories for causes.

Be careful when naming your causes, always making them measurable and non-descriptive. (Slides 22, 23) 5- See where the use of another tool like a statistical graph or chart can be useful. (Slide 24) 6- For at least one of the causes develop it into a new fishbone diagram. (Slides 33, 34) For more information on Rust  read this: https://en.wikipedia.org/wiki/Rust
