The Insight
Slide 22
2020 has been a year.
Slide 23
Throughput
Slide 24
Throughput in a global pandemic
Slide 25
Peak Throughput was in April 2020
Slide 26
Duration
Slide 27
Duration in a global pandemic
Slide 28
Hypothesis: more tests written in March, driving up Duration. In April, a concerted effort on optimization

Hypothesis: people working hard on core business stability
Slide 34
Recovery Time
Slide 35
Recovery time in a global pandemic
Slide 36
Hypothesis: few distractions* working at home
Slide 37
Important to set targets Throughput The average number of workflow runs per day Duration The average length of time for a workflow to run Mean time to recovery The average time between failures & their next success Success rate The number of successful runs / the total number of runs over a period of time Median CircleCI Developer Suggested Benchmarks 0.7 times/day Merge on any pull request < 4 minutes 5-10 minutes < 56 minutes Under 1 hour 80% for default branch 90% or better on default branch
Slide 38
Things that make you go 🤔
Slide 39
Success Rate on default branch higher than on non-default
Slide 40
Duration on default branches faster at every percentile
Slide 41
Recovery Time lower on default branches at every percentile
Slide 42
What development practices definitively work?
Slide 43
Success Rate does not correlate with company size
Slide 44
Duration is longest for teams of one
Slide 45
Recovery Time decreases with increased team size (up to 200)
Slide 46
Performance is better with >1 contributor
Slide 47
Software is collaborative

“Don’t deploy on Friday” is not a thing.
Slide 53
“Don’t Deploy on Friday” is not a thing ○ 70% less Throughput on weekends ○ 11% less Throughput on Friday (UTC) ○ 9% less Throughput on Monday (UTC)
