Stuff just gets done, I guess? Projects move faster, people onboard faster with less intervention, etc. The speedup seems noticeable enough that it doesn’t need precise measuring.
If the speed up is noticeable enough then coming up with a metric should be easy?
I haven’t noticed a speed up in my own org though the feeling of engineers rushing to implementation has become more pronounced. Team members no longer understand what others are doing and siloing has become intense even within my team.
