please respond to the following questions on Chapter $7$ in Schwalbe $$ An Introduction to Project Management

Kristin and her team analyzing Just$-$In$-$Time $($JIT$)$ Training project $($i$.$e$.,$ the opening chapter case$)$ used a fishbone diagram to examine the cause$-$and$-$effect of the low rating issues surrounding the project. Do you think this was a good decision? Why?

Are there any other tools that might prove just as effective or provide a more in$-$depth view of the issues?

Did the fishbone diagram provide Kristin and her team enough information to resolve the issue$($s$)?$

Do you think there were other causes that were not identified in the fishbone diagram?
