Things that make you go 🤔

Branch information

No significant change in default branch from master… yet.

Success Rate on default branch higher than on non-default

Duration on default branches faster at every percentile

Recovery Time lower on default branches at every percentile

What development practices definitively work?

Success Rate does not correlate with company size

Duration is longest for teams of one

Recovery Time decreases with increased team size (up to 200)

Performance is better with >1 contributor

Software is collaborative

“Don’t deploy on Friday” is not a thing.
