In most project or ticket systems:
– **P1 (Priority 1)** – Critical issue, blocks major functionality, needs immediate attention, usually worked on ASAP.
– **P2 (Priority 2)** – High priority but not a complete blocker, important to fix soon, but can wait until after P1 issues.
Think of it as:
– **P1** → "Production fire, fix now" 🔥
– **P2** → "Serious, but not on fire" ⚠️
