Collaboration is an interaction mode in which two teams work together toward a shared outcome. Both teams change their own areas, while success depends on staying aligned through close coordination. That alignment carries a high cognitive-load cost, so collaboration is appropriate only when its benefits outweigh reduced team output. section 11.2.2
Collaboration typically involves:
- Synchronizing work through shared rituals, joint decision-making, and frequent communication. section 11.2.2
- Reconsidering the relationship as context and workload change; switch to X-as-a-service or remove the relationship when close alignment no longer justifies its cost. section 11.2.2
Overloaded integration platform team
A global cosmetics brand’s integration platform team collaborated with at least four other teams, building and maintaining custom endpoints because those teams lacked skills or budget. The resulting coordination load made the platform team a bottleneck. Mapping the topology created shared agreement to stop accepting work outside the platform’s responsibility and hand over existing responsibilities. section 11.2.3
