(Change fail rate is not included staBsBcally.) Discovered Three dis3nct groups of IT Performers: High, Medium, Low ◦ Analysis shows throughput and stability metrics move in tandem – effecBvely disproving ITIL claims that tradeoffs are necessary. Established a link between IT Performance and Org Performance ◦ Tying IT acBviBes and investments to profitability, market share, and producBvity is HUGE
3. 2015 State of DevOps Report GOALS  Revalidate Core Findings from 2014 SoDO Report ◦ IT Perf Measures sBll move in tandem ◦ Link between IT Performance and OrganizaBonal Performance  InvesBgate drivers of IT Performance – in a fully predic3ve model ◦ 2014 report largely reported correlaBons ◦ Expand to invesBgate impacts on how work *feels*  Look at demographics  InvesBgate a hunch in architecture…
