Lyrics

[Verse 1]
Sarah built the logging lib that half the world depends upon
Working nights and weekends, keeping servers running strong
But she's burning out from pressure, thinking bout a different path
One developer maintaining what supports our digital past

[Chorus]
Bus factor one means danger zone
When knowledge lives in minds alone
Single point of failure here
Makes the whole supply chain fear
Check your deps before they're gone
Bus factor one, bus factor one

[Verse 2]
GitHub shows the commit graph, one name dominates the green
Issue tracker piling high with bugs she's never seen
No succession plan in place, no backup maintainer found
When she steps away tomorrow, will your system hit the ground

[Chorus]
Bus factor one means danger zone
When knowledge lives in minds alone
Single point of failure here
Makes the whole supply chain fear
Check your deps before they're gone
Bus factor one, bus factor one

[Bridge]
Look at contributor metrics, count the active hands
Check the project governance, understand their plans
Fork or fund or find alternatives before the crisis hits
Human sustainability matters more than perfect fits

[Verse 3]
Map your critical dependencies, audit every single one
Count the maintainers actively working, rate them by the sun
Red flag packages with solo devs carrying the load
Yellow warning signs for projects on a lonely road

[Chorus]
Bus factor one means danger zone
When knowledge lives in minds alone
Single point of failure here
Makes the whole supply chain fear
Check your deps before they're gone
Bus factor one, bus factor one

[Outro]
Build resilience in your stack today
Before your heroes walk away
Bus factor planning saves the day
