Building and Scaling High Performing Technology Organizations

How can we apply technology to drive business value? For years, we’ve been told that the performance of software delivery teams doesn’t matter―that it can’t provide a competitive advantage to our companies. Through four years of groundbreaking data collection research, Jez Humble and his colleagues found a way to measure software delivery performance―and what drives it―using rigorous statistical methods. This talk presents the findings of that research, including how to measure the performance of software teams, what capabilities organizations should invest in to drive higher performance, and how software leaders can apply these findings in their own organizations.

  5. @jezhumble a note about predictive analysis One of three conditions

    must be met: • Randomized, experimental design (no, this is non-experimental) • Longitudinal (no, this is cross-sectional) • Theory-based design When this condition was not met, only correlations were tested and reported .
  6. software delivery as a competitive advantage “Firms with high-performing IT

    organizations were twice as likely to exceed their profitability, market share and productivity goals.” http://bit.ly/2014-devops-report
  7. software delivery as a competitive advantage high performers were more

    than twice as likely to achieve or exceed the following objectives: • Quantity of products or services • Operating efficiency • Customer satisfaction • Quality of products or services provided • Achieving organizational and mission goals • Measures that demonstrate to external parties whether or not the organization is achieving intended results http://bit.ly/2018-devops-report
  8. @jezhumble time to restore service lead time for changes (version

    control to production) deploy frequency change fail rate software delivery performance http://bit.ly/2014-devops-report
  9. elite performers http://bit.ly/2018-devops-report Data shows a new 4th high performance

    group: elite performers Proportion of high performers has grown YoY, but the bar for excellence remains high Elite performers are still able to optimize for throughput and stability
  10. availability http://bit.ly/2018-devops-report Ability for teams to ensure their product or

    service can be accessed by end users Software delivery + availability = SDO performance Elite performers are 3.5X more likely to have strong availability practices
  11. capabilities that drive high performance Accelerate: The Science of Lean

    Software and DevOps, Forsgren, Humble and Kim 2018
  12. @jezhumble key finding: architectural outcomes can my team… …make large-scale

    changes to the design of its system without the permission of somebody outside the team or depending on other teams? …complete its work without needing fine-grained communication and coordination with people outside the team? …deploy and release its product or service on demand, independently of other services the product or service depends upon? …do most of its testing on demand, without requiring an integrated test environment? …perform deployments during normal business hours with negligible downtime? http://bit.ly/2017-devops-report | https://devops-research.com/research.html | DORA / Puppet
  13. @jezhumble key finding: doing cloud right http://bit.ly/2018-devops-report | NIST SP

    800-145 AGREED OR STRONGLY AGREED On-demand self-service Broad network access Resource Pooling Rapid elasticity Measured service Only 22% of teams are doing cloud right! Teams that use these essentials characteristics are 23X more likely to be elite performers
  14. @jezhumble monitoring and observability MONITORING is tooling or a technical

    solution that allows teams to watch and understand the state of their systems and is based on gathering predefined sets of metrics or logs. OBSERVABILITY is tooling or a technical solution that allows teams to actively debug their system and explore properties and patterns they have not defined in advance. Teams with a comprehensive monitoring and observability solution were 1.3 times more likely to be an elite performer. Having a monitoring and observability solution positively contributed to SDO performance. Fun stats fact: monitoring and observability load together.
  15. @jezhumble which of these measure effective test practices? • Developers

    primarily create & maintain acceptance tests • QA primarily create & maintain acceptance tests • Primarily created & maintained by outsourced party • When automated tests pass, I’m confident the software is releasable • Test failures are likely to indicate a real defect • It’s easy for developers to fix acceptance tests • Developers share a common pool of test servers to reproduce failures • Developers create on demand test environments • Developers use their own dev environments to reproduce failures

  17. @jezhumble continuous testing previous practices plus… • continuously reviewing and

    improving test suites to better find defects and keep complexity and cost under control • allowing testers to work alongside developers throughout the software development and delivery process • performing manual test activities such as exploratory testing, usability testing, and acceptance testing throughout the delivery process • having developers practice test-driven development by writing unit tests before writing production code for all changes to the codebase • being able to get feedback from automated tests in less than ten minutes both on local workstations and from a CI server http://bit.ly/2018-devops-report | https://devops-research.com/research.html
  18. @jezhumble lean product management Regularly gathering, broadcasting, & implementing customer

    feedback Splitting work into small batches that can be completed in <1 week & released frequently Teams have a good understanding of the flow of work from business to customers Teams have the authority to create and change specifications as part of the dev process Software delivery performance Less burnout Westrum culture Lean product management Organizational performance
  19. high trust culture Westrum, “A Typology of Organizational Cultures” |

    http://bmj.co/1BRGh5q how organizations process information
  20. @jezhumble identity and Google items • 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. Adapted from adapted from Atreyi Kankanhalli, Bernard C.Y. Tan, and Kwok-Kee Wei (2005), “Contributing Knowledge to Electronic Knowledge Repositories: An Empirical Investigation,“ MIS Quarterly, 29, 113-143. Westrum items
  21. @jezhumble ask: how can we get people better information? in

    a complex, adaptive system failure is inevitable when accidents happen, human error is the starting point of a blameless post-mortem ask: how can we detect and limit failure modes? dealing with failure
  22. @jezhumble disaster recovery testing “For DiRT-style events to be successful,

    an organization first needs to accept system and process failures as a means of learning… We design tests that require engineers from several groups who might not normally work together to interact with each other. That way, should a real large-scale disaster ever strike, these people will already have strong working relationships” Kripa Krishnan | http://queue.acm.org/detail.cfm?id=2371297 —Kripa Krishnan, Director, Cloud Operations, Google
  23. “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.” innovation culture http://glinden.blogspot.com/2006/04/early-amazon-shopping-cart.html
