Explain How a Service Actually Works
A practical way to capture the real behaviour of a service - including the awkward parts diagrams leave out.
"How does this service work?" is one of the most expensive questions in engineering. The answer often requires a senior engineer, a hunt through outdated docs, and a few tribal stories that never made it into the wiki.
A useful service explanation
- 1
State the job in plain language
What does this service own? What does it refuse to own? Ambiguity here causes bad designs later.
- 2
Name the critical dependencies
Upstream and downstream systems that matter under failure, not every library in package.json.
- 3
Surface non-obvious behaviour
Retries, caches, backdoors, "temporary" queues, and weekend batch jobs that still matter on Tuesday.
- 4
Attach the history that still constrains you
Migrations abandoned, compliance decisions, capacity incidents - the reasons certain changes are hard.
- 5
Point to people
Who owns it operationally? Who has deep expertise? Who last made a significant change?
