I think Taguchi methods would greatly benefit the #tech industry.
The methods describe using loss functions to measure results in $ terms. That really helps calibrate bets. https://en.m.wikipedia.org/wiki/Taguchi_methods">https://en.m.wikipedia.org/wiki/Tagu...

Genichi Taguchi showed how the cost of errors can be incorporated into measurement.
This is useful for #devops. Taguchi like Deming learned that retros don& #39;t lead to improved process. Error budgets provide a long term view that reduces stress!

They do this by creating expectations that allow management to prioritize and plan investment. No investment? No change in expectations.
Measuring in $ terms is critical because it& #39;s the only way to compare the work to revenue and hence get prioritization.

Retros don& #39;t work. I know that& #39;s super controversial but the two top reliability statisticians of all time came to that conclusion. Why?
Simple. The failure already occured, it& #39;s logically too late to understand what happened. A house of mirrors.

Oh, you found the cause? That& #39;s not the cause, so fixing the apparent root cause won& #39;t help. Instead, it takes time away from reliably and repeatedly diagnosing the cause.
By measuring errors/alerts/failures per unit of time, applying costs (yes this is a justifiable guess/estimate), setting error budgets, prioritizing fixes ahead of errors, high reliability and low stress can be achieved!
Errors and failures are best handled at the systems engineering / design level.
