It may involve a man driving past the home of his former wife on the way to work.

The focus must be brought back to gendered nature of this violence. If we fail to recognise the dynamics of power behind domestic violence we have little chance of addressing the root causes and turning the tide on the 63,000 domestic violence incidents recorded in New Zealand a year.

To quantify root cause/s (note the plural!) and remove or mitigate requires accurate statistical analysis and the motivation to remove/mitigate the cause/s.

The data presented gives no information on actual occurences of domestic violence (police incident catergorisations are not a casual indicator and it is doubtful if they are an unbiased and accurate record)

The biggest barrier to root cause removal is mistaking common cause variation as special cause variation due to poor data sources and ideologically bound analysis.

Looking at the “noise” (common cause variation) of the system leads on a merry goose chase and ignores the signals from the system (Special/Assingable Cause variation)

Root cause analysis (my bread and butter trade) requires listening to the voice of the process and understanding what it is really telling you. This analysis wants you to listen to the noise of the process and jump to unsupportable conclusions.

The result is ill informed commenatary like this as reported by Hans.
