Real-World Roleplays

Discussing an API change with a frontend developer.

BA
Backend DeveloperWe need to deprecate the v1 user endpoint because the new schema requires fetching related permissions.
FR
Frontend DeveloperWill this break existing clients?
BA
Backend DeveloperYes, it's a breaking change. Let's schedule a migration window next week so you can update the requests.
FR
Frontend DeveloperSounds good. Can you share the new JSON payload structure?

Explaining a performance bottleneck.

TE
Tech LeadWhy did the latency spike during the marketing campaign?
BA
Backend DeveloperThe database query for fetching user analytics lacks an index on the timestamp column, causing full table scans.
TE
Tech LeadHow do we mitigate this?
BA
Backend DeveloperI've created a migration to add the index, and we should also implement caching for the aggregate results.

Common Questions

How do I explain technical debt in English?
Use analogies like 'borrowing time' to explain that cutting corners now requires extra work later to fix.
What phrases are useful for proposing architectural changes?
'I propose we transition to...', 'The main trade-off is...', or 'This approach improves scalability by...'.
How can I describe security issues sensitively?
Use objective language like 'I identified a vulnerability in...' rather than 'You wrote insecure code.'
