The big issues we had were because we had different services reaching into and editing the same db tables in some cases. Re-architecting to have all data access via a new API (instead of direct DB access) across 13 services ran by 8 different teams across 2 business orgs has proven hard. The other thing that can be a pain is due to rigid agile sprints. Need a change? Well that might get into their next sprint but there are probably other, higher priorities, so maybe next quarter. Or team A just does the work on team B’s service, and waits for code reviews and quality checks.
