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

"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

• Effective test data management

• Test & Deployment automation

• Trunk-based development

• Continuous integration

• Version control• Shifting left on

security

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

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%

Lean Management Practices

• Effective WIP limits

• Visual displays• Monitoring tools• Gathering,

montoring, implementing customer feedback

• Small batches• Making work

visible through the value stream

@nicolefv

Visual Displays

“If it moves, graph it.” - Michael Rembetsy, Former VP Operations, Etsy

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 able to:

• Reduce test time preparation time significantly

• Release software with noincidents

• Deliver on time and on budget

“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.”

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
