Team Topologies in Practice: A Journey of Re-Teaming Using Architecture for Flow
Talk
In this talk, we'll share our hands-on experience applying Architecture for Flow (combining Wardley Mapping, DDD, and Team Topologies) to transform a growing software organization. Pirate Ship, a growing tech company, faced common scaling challenges: teams growing too large, unclear ownership of shared components, and dependencies blocking the flow.
Working with development teams across multiple workshops and iterations, we established stream-aligned teams with well-defined ownership boundaries.
We'll demonstrate how we used participatory approaches to map stream-aligned teams to identified bounded contexts and introduced a platform team. Through concrete examples, we'll show how combining software architecture with team topology patterns led to sustainable flow optimization.
Key Takeaways:
- A practical blueprint for participatory team reorganization combining Wardley Mapping, Domain-Driven Design, and Team Topologies
- Proven workshop formats for domain discovery and team self-selection
- How to use consent-based decision making and self-selection to drive sustainable change
- Strategies for evolving from shared components to platform teams
