The XP 2018 conference in Porto, Portugal, focused on various Agile methodologies and practices, attracting 300 participants from 37 countries. Keynotes included discussions on continuous deployment, security, and Kent Beck's 3x model for company growth stages: explore, expand, and extract. The conference emphasized the importance of experience reports in Agile and the value of mob programming for learning, alongside insights into the emotional aspects of development.
![3X Model
Kent Beck (Keynote Wednesday)
Three Rivers Institute
Kent shared a bit about his 3X model about
stages of a company, startup to maturity.
The 3X stands for Explore, Expand and
Extract. Across these three stages, a company
has changing priorities, coding standards,
and concerns.
Although a company might itself be very
mature, it can have exploration-stage
projects, and expand-stage projects,
alongside extract-stage.
The 3X phases frame the context in which certain values, principles and practices apply.

“Explore–the risky search for a viable return on a viable investment [via
experimentation]…If you’re lucky, one of these experiments turns out to be
unexpectedly successful, which leads to:
Expand–now things are going nuts… Unanticipated bottlenecks
appear… Once growth becomes routine, it’s time to:
Extract–now the shape of the problem and solution spaces
are clear. One euro in equals three euros out. Playbooks
emerge…Economies of scale matter…”](https://image.slidesharecdn.com/xp2018presentationforphxsug2018-180720133325/85/XP2018-presentation-for-Phoenix-Scrum-User-Group-2018-10-320.jpg)

Improving User Stories Improving Estimation IoT – XP-style – IoT as MicroServices
- 6. Experience Reports The Agile Experience Report Program promotes the writing and timely sharing of firsthand Agile experiences. https://www.agilealliance.org/res ources/experience-reports
- 7. Experience Report: Scrum Master as Team Member -Power Utility Project Accounting System (defect fixes & enhancements) • 12 hour work day was normal through 12 month project. • PM was not agile-friendly, but agreed to let the team try so long as client agreed. • Client was willing and excited to see 2- week progress. • Dual role was not original intent, but team requested this to help ensure success. • Scrum tools were set up just before Sprint 1 (IntelliJ, Jira/Confl/Fisheye, etc.) • Tried to add TDD, but team did not buy in. • Tried to add Mob Programming, but team also did not align. • Allowed Mark to build skills in others. • Required high social skills in Mark, along with technical expertise. • Dual role required balancing the perspective of both roles. • Exhausting but rewarding!

- 8. Continuously Deploying Security Security requirements are typically a non- functional requirement vs. within a User Story Communication + Culture + Technology + Education Security testing requires automated testing Feature Flags allow deployment of security improvements and testing in production without impacting customers Deployment needs to be automated to ensure ‘perfection’ and compliance Security features will be low on the Product Owner backlog, but mandatory on the corporate prioritization Protection Poker (Laurie’s PDF) Impact vs. ease of attack Microsoft Game: Elevation of Privilege Use Blameless Retrospectives (no guilt) - just critical analysis of ‘what I did’ and ‘why it failed’ – enables innovation and learning Automated Testing is critical Test for recovery AFTER failure Deploy AT PEAK LOAD as a great test! Laurie Williams (Keynote Tuesday) North Carolina State University To understand the emerging practices surrounding continuous deployment, three annual one-day Continuous Deployment Summits have been held at Facebook, Netflix, and Google in 2015- 2017, where 16 companies have described how they used continuous deployment.

- 12. 3X Model – Implications to the Tech Debt Challenge
- 13. Emotions & Success of Code-Builds Another tidbit from a research team: Analyzing the CI Log from GitHub can give insight to developer emotions Anger is a significant variable for our model, and higher levels of anger are linked with failure builds. Learning: Don’t make your Devs mad! Arousal, dominance, sadness, joy, love – these were not as significant.

- 14. Mob Programming for Learning Mobbing is like dancing Enables constant learning Pilot / co-pilot (if 2) Pairing all the time is like being in a relationship; Mobbing all the time is like being in a family. What is your experience with mobbing and pairing?
