Root cause analysis and pareto chart
Can any one tell what is the common practice in industry to do causal analysis and plotting of pareto chart.Is it plotted against defect type or defect cause?
Thanks in advance.
Re: Root cause analysis and pareto chart
We want to reduce our project defect count.
We note 80% of defects are GUI type errors
We note 80% of defects are caused by coding errors
If I understand correctly, I would want to consider both, and so in this example root cause for most errors will be found by studying how we're building our interfaces?
