When we are searching for the problem root cause, as far as I know from previous knowledge, we should avoid asking: who?
Because the intention is not to blame people, but to fix the system. (...) Read more? Sign up for free

8D and 5Why
If root cause is not very obvious, use the 5 whys is a good method.

8D's & 5Why's
The use of 5 Why's or 8D will ultimately give you the list of key root causes to eliminate or minimise the impact of the problem.
However if you really want to quantify the level improvement effort and measure the impact you are creating than you may want to separate if the causes are "common" or "special" causes. Then develop a data gathering plan to understand the impact before and after so you can quantify the impact you create in solving the problem.
Some statistical tools to look at would be, Pareto charting, Hypothesis testing, Regression analysis, Process capability etc...
