High performers● Deployment frequency =
On demand (Multiple times per day)
● Lead time for changes = Less than 1 hour
● Mean Time to Recover = Less than 1 hour
● Change Failure Rate = 0% - 15%
DevOps Research and Assessment (DORA) has found that for high performing IT organizations:
● correlate to Generative Cultures● are twice as likely to exceed their profitability,
market share and productivity goals● achieved higher levels of throughput AND stability● spend more time on new work / less on rework
Also: IT performance is predictive of the
performance of the organization as a whole.
