Note: At a minimum this does not take into account:
1. Any Negative flows at transition points
2. Performance Testing
3. Pre-Release Validations
4. UAT readiness and support activities in NP5
5. Production Release Activities
Key:

Results
• Heroes and single points of failure – Shared knowledge and leveling up
• Code quality – Code coverage, pair programming, collaboration and CULTURE!
• Tight coupling between systems – Decoupled systems
• Release dependencies across several development teams – Team and domain
autonomy
• Extended period of time for manual regression testing – Unit tests, Integration
tests, Component tests and End-to-End tests
• Extended period of time between releases – Fast feedback loops
• Manual involvement in release process – Automation – CI/CD
• Scalability issues related to performance and resources – Auto scaling and
flexibility of usage

Moving Forward
• Continue to extract functionality out of monoliths (such as WebSphere Commerce)
• Enable product teams to iterate quickly and independent of each other
• Facilitate any/all ceremonies to further enable product teams to begin their
modernization efforts
• Onboard .NET/Steeltoe teammates so that more product teams can be supported
and engaged
• Continue knowledge sharing with more recipes in the cookbook and additional tech
meetups to drive efficiency

13. | Driven | Skilled | Passionate | Committed |
Engagement Options
• Facilitation strategy:
• AppTx team facilitates the initiation of the modernization process but is not an
active participant in the engineering effort
• This works well if the team has modernization knowledge and capacity to
focus on the modernization effort
• Supplement strategy:
• AppTx team supplements engineering efforts for a product team, sharing
modernization techniques and practices to drive team effectiveness and
productivity
• This works well if the team does not have modernization knowledge but has
capacity to focus on the modernization effort
13

14. | Driven | Skilled | Passionate | Committed |
Engagement Options
• Engage strategy:
• AppTx team drives engineering efforts for a product team (engaging engineers
as much as they are available), sharing modernization techniques and
practices to drive team effectiveness and productivity
• This works well if the team does not have modernization knowledge or
capacity to focus on the modernization effort
• Internship/Rotation strategy:
• Engineers pair with AppTx team for a period of time (1-3 weeks), sharing
extreme programming techniques and practices to drive team effectiveness
and productivity
• This works well if the team does not have extreme good programming
practices
