IT Does Matter• Times – and IT – have changed•DevOps is good for Organizations•DevOps is good for IT•And then some detail: What drives this change?• Technical practices (hint: Continuous Delivery)• Management practices (hint: from Lean Management)• Culture and identity
@nicolefv
DevOps isTechnical practices
seen in Continuous Delivery,Management practices
seen in Lean Management principles, and Organizational Culture
@nicolefv
Research shows that these drive Organizational Performanceand IT Performance

Devops is good for IT
Measuring DevOps and IT Performance- Deploy frequency (when business demands)- Lead Time for Changes- Mean Time to Recover (MTTR)- Change Fail Rate

DevOps promises – and delivers More throughput
More stability
In tandem. Without the tradeoffs that ITIL calls for.
Let’s talk about what this means for us@nicolefv

"Fixing it as soon as possible or having compensating controls in place
days before could have saved this entire breach from occurring in the
first place."
We know:
• IT Performance is comprised of throughput and stability, and both are possible without tradeoffs• IT Performance contributes to org performance
(profitability, productivity, market share)
So:What drives IT and Organizational Performance?

Continuous Delivery
@nicolefv
Continuous Delivery
• Effective test data management
• Test & Deployment automation
• Trunk-based development
• Continuous integration
• Version control• Shifting left on

Test Data Management
Analysis showed that data was creating bottlenecks in the process.
Key activities in TDM include:• Test data masking and
subsetting• Test data automation• Integration with tooling
Outcomes:• Faster time to market• Improved quality and customer
experience• Significant productivity improvements
and savings• Improved testing efficiencies

Test & Deployment Automation
“By getting new releases and services out the door quickly, we can provide a better experience to millions of car buyers and sellers and continue to differentiate ourselves in a competitive market.” -- Adam Mills, Senior Manager of Application Development, AutoTrader.com
Using a DevOps approach to unify teams, they have been able to automate their test, build, and deployment
Using these principles, Autotrader.com has been able to:• Reduce test, build, and deploy times from
weeks to just minutes• Decrease software defects by 25%

Continuous Delivery also makes our work feel better
• Effective test data management
• Deployment automation
• Test automation• Trunk-based
development• Continuous
integration• Version control• Shifting left on
security Decreases burnout and deploy pain

Making Work Visible Through the Value Stream
“One of the greatest effects… is that we are now asked much earlier by the business to participate in the requirements gathering process.” -- Project Manager at a.s.r.
By creating flowcharts to show work as it moved throughout the value stream, a.s.r. was able to leverage insights from all stakeholders including business, test, and IT. Leveraging these tools, teams could immediately understand changes made to requirements and their impact.
Using this principle, a.s.r. was been able to:• Reduce test time preparation time
significantly• Release software with no incidents• Deliver on time and
on budget

Decreases burnout
“I was trying to figure out why my team was working themselves to death but not getting anything done… By implementing WIP limits, we were able to focus on our work. Finishing work feels better than sprinting and feeling like a hero in the moment, because that’s only a moment.”

Low cooperation Modest cooperation High cooperation
Messengers shot Messengers neglected Messengers trained
Responsibilities shirked Narrow responsibilities Risks are shared
Bridging discouraged Bridging tolerated Bridging encouraged
Failure leads to scapegoating Failure leads to justice Failure leads to inquiry
Novelty crushed Novelty leads to problems Novelty implemented
Identity• I am glad I chose to work for this organization rather than another company.• I talk of this organization to my friends as a great company to work for.• I am willing to put in a great deal of effort beyond what is normally expected to
help my organization to be successful.• I find that my values and my organization's values are very similar.• In general, the people employed by my organization are working toward the
same goal.• I feel that my organization cares about me.

“By installing a rampant innovation culture, we performed 165 experiments in the peak three months of tax season.
Our business result? Conversion rate of the website is up 50%. Employee result? Everyone loves it, because their new ideas can make it to market. ”

“I think building this culture is the key to innovation. Creativity must flow from everywhere. Whether you are a summer intern or the CTO, any good idea must be able to seek an objective test, preferably a test that exposes the idea to real customers. Everyone must be able to experiment, learn, and iterate.”
- Greg Linden
