Should we focus more on measuring the results, or the process that get us there?
This is the constant balancing act that we all address. I personally prefer to work on the processes that ensure high quality. But without some measures on quality, how do we know these are working?
Until someone invents a foolproof process, I would guess we still have to do both.
We can, however, take steps to remove errors from our engineering processes, from machine setups and human interactions that significantly reduce the number of defects found at our quality assurance stages that all build to reduce production cost and make happier customers.
Thankfully we have skills and tools which can make this a systematic approach to quality.
I would be happy to share my experience.
