2. CROSS SECTION BETWEEN INNERSOURCE & AGILE WHY OSCON? ▸ Improved engagement & gave my work purpose ▸ Rate of learning & exposure ▸ Skill development through contributions to diverse communities ▸ Work life balance through ongoing skill development ▸ Still in tech due to open source meet ups and conferences
3. OVERVIEW ▸ Sprint Safe Disengagement ▸ Leads to further engagement throughout the enterprise ▸ Enables additional InnerSource contributions ▸ Accelerate a unit’s velocity toward shared goals ▸ What is InnerSource? CROSS SECTION BETWEEN INNERSOURCE & AGILE
4. INCREMENTAL ARCHITECTURE
5. INCREMENTAL ARCHITECTURE STOP WRITING TECHNICAL STORIES
6. BUT, A LARGE PERCENTAGE OF OUR BACKLOG ARE ALL TECHNICAL STORIES ! Individual Contributor INCREMENTAL ARCHITECTURE
7. A NARRATIVE THAT TAKES A USER THROUGH SOME PROCESS THAT RESULTS IN A VALUABLE OUTCOME FOR THAT USER. @allenholub on User Stories INCREMENTAL ARCHITECTURE
8. TRY TO REPRESENT THE TECHNICAL REQUIREMENT AS TASKS WITHIN ONE OF THE FUNCTIONAL USER STORIES THAT IS RELIANT ON THIS TECHNICAL WORK Scrum Shortcuts Without Cutting Corners: Agile Tactics, Tools, & Tips INCREMENTAL ARCHITECTURE
9. WHY ROLL UP TECHNICAL TASKS INTO USER STORIES? ▸ Product Owner & Team ▸ Avoid tasks being ignored due to being “uninteresting to the customer” (Kniberg 2011) ▸ Appreciation for technical complexity inherent within stories INCREMENTAL ARCHITECTURE
10. WE HAVE TO DO TECHNICAL TASKS FOR OUR PROJECTS, BUT LET'S REPORT PROGRESS IN TERMS OF VALUE: DELIVERING WHAT CUSTOMERS WANT. http://bit.ly/2Ovy6JW INCREMENTAL ARCHITECTURE
11. “TECHNICAL STORIES” ARE THE TASKS THAT ROLL UP UNDER USER STORIES
12. YOUR CODE'S DESIGN MUST EVOLVE ALONG WITH YOUR UNDERSTANDING OF THE PRODUCT. https://holub.com/product/incremental-architecture/ INCREMENTAL ARCHITECTURE
13. INCREMENTAL ARCHITECTURE INVEST ▸ Independent ▸ Negotiable ▸ Valuable ▸ Estimate-able ▸ Small ▸ Testable
14. INCREMENTAL ARCHITECTURE WHY, WHAT, HOW, AND WHO? ▸ Why - Why is this story being proposed? ▸ What - What problem is it intending to resolve? ▸ How - How does this benefit the business? ▸ Who - Who benefits from it? What’s the impact? https://www.scrum.org/forum/scrum-forum/12317/technical-stories
15. WHAT OBSERVATIONS CAN WE MAKE FROM A USER STORY PERSPECTIVE? # Individual Contributor CROSS SECTION BETWEEN INNERSOURCE & AGILE

17. SPRINT SAFE DISENGAGEMENT SIGNALS TO INDIVIDUAL CONTRIBUTORS THAT THEY CAN REST EASY TONIGHT, AND INTO THE FUTURE.
18. SPRINT SAFE DISENGAGEMENT WHAT IS SPRINT SAFE DISENGAGEMENT? ▸ Revolves around ▸ What does the code review/definition of done require? ▸ What’s going to boomerang anyway while on call?
19. SPRINT SAFE DISENGAGEMENT ON TRACK USER STORIES: WHAT MIGHT A CODE REVIEW ENTAIL? ▸ What is the code coverage of the feature in development? ▸ Test coverage? ▸ Ops ▸ Logs, Metrics, Dashboards, and Alerts ▸ At 2:30 am, groggy and sleepy, how much effort will it take to restore service, or, answer questions about current operation of a feature in prod?

22. WHAT IS SPRINT SAFE DISENGAGEMENT GETTING ME? ▸ Code reviews are quick and in sprint ▸ Prod support kept to a minimum, less pages after hours ▸ Observability is maintained and improving as the code base evolves, per story or pull request ▸ Contributing with far higher levels of engagement across the organization, not just a given silo () SPRINT SAFE DISENGAGEMENT
23. WHAT IS INNERSOURCE?
25. A WAY TO INCREASE COLLABORATION, CROSS TECH KNOWLEDGE, EASE BOTTLENECKS, AND ASSIST TEAMS IN GETTING NEEDED CHANGES IMPLEMENTED IN STACKS THEY DON’T OWN Checking Out InnerSource at PayPal CROSS SECTION BETWEEN INNERSOURCE & AGILE
26. ENGINEERS WERE ABLE TO FIND A NEW PURPOSE AND RENEW THE ENTHUSIASM THAT THEY MIGHT HAVE LOST OVER THE YEARS. Living in a BIOSphere at Robert Bosch CROSS SECTION BETWEEN INNERSOURCE & AGILE

29. INNERSOURCE SUPPLEMENTATION WHY FAVOR INNERSOURCE? ▸ Momentum is often far greater and has wider focus ▸ Less engineering effort for your team/silo ▸ Less ongoing maintenance from team perspective ▸ Contributors have impact beyond their immediate team ▸ Active internal support inside the organization
30. INNERSOURCE PROVIDES ANOTHER LEVEL OF COLLABORATION BETWEEN UNITS BY SHARING BACKLOGS Connecting Teams with InnerSource at Erickson INNERSOURCE SUPPLEMENTATION
31. FAVOR PULL REQUESTS OVER FEATURE REQUESTS ▸ Additional velocity related to originating user stories ▸ Team needs enough bandwidth per sprint to allow for this ▸ Trusted Committer ▸ In other words ▸ Write access to a repo outside a contributor’s domain INNERSOURCE SUPPLEMENTATION
32. THE WORK SHOWN ON A PULL REQUEST WAS A CLEARER BASIS FOR DISCUSSION THAN INFORMAL REQUIREMENTS COMMUNICATED ACROSS UNIT BOUNDARIES Borrowing Open Source Practices at Europace INNERSOURCE SUPPLEMENTATION
33. THE BEST CONTRIBUTIONS ARE SMALL AND FREQUENT Connecting Teams with InnerSource at Erickson INNERSOURCE SUPPLEMENTATION
34. LEVERAGE INNERSOURCE ▸ Pull in what’s available ▸ Communities of practice (cop) ▸ Contribute or demo improvements in a related cop ▸ Enterprise aware INNERSOURCE SUPPLEMENTATION
35. PAY IT FORWARD ▸ Write a blog post ▸ Give a talk ▸ Share how the experience impacted your day to day work ▸ Tell your story, build others up INNERSOURCE SUPPLEMENTATION
36. TO GIVE ANYTHING LESS THAN YOUR BEST, IS TO SACRIFICE THE GIFT. Steve Prefontaine CROSS SECTION BETWEEN INNERSOURCE & AGILE
