I am an offshore QA and work in an Insurance domain. I am trying to make a project on team accuracy which would be helpful to find a root cause for repetition of errors. So far, I have made a project charter, Voc, Sipoc and even collected 10 month data and calculated STD deviation. (I used reference from Google).
My questions
1. How should I move forward with above or am I doing something incorrect?
1. How should I choose what tools to be used.
2. I started this with the intention to have the team accuracy over to 95% which is now approx 91. Please advise guide me on this. Thanks
