Flag and notify/inform both involve telling someone about something, but they claim different things about how complete that communication is.
Notify and inform foreground the recipient and a completed act of communication ("notify HR of the change"); flag foregrounds the item's priority, with a different object pattern ("flag the change for HR"). Notify/inform claims the communication itself happened and is now complete; flag claims the item is now marked as a priority, which is a narrower and sometimes earlier step than a full formal notification.
A completed act versus a marked priority
Notify: "We notified HR of the policy change ahead of the rollout." Flag: "We flagged a gap in the new policy that HR should review before rollout."
Inform: "Please inform the client of the delay by end of day." Flag: "Please flag the delay to the client contact by end of day, so they can plan around it."
In each pair, the notify/inform version reports something as done -- HR has been told, the client has been informed. The flag version instead marks something as needing attention, without necessarily claiming the full formal communication has already taken place.
Don't let a flag substitute for a required notification
This distinction matters most when a process, policy, or contract specifically requires notification. Flagging something informally -- in a channel, a comment, a quick note -- is not automatically the same as fulfilling a notification requirement, even if the substance overlaps. If a formal notify or inform step is required somewhere in the process, flag alone doesn't complete it; it can precede or accompany that step, but it isn't a substitute for it.

Notify and inform aren't quite the same as each other, either
Worth a brief note in passing: notify and inform aren't perfect synonyms of each other, even though both are grouped together here as a paired near-word to flag. Notify tends to carry a slightly more formal, procedural tone -- "notify the authorities," "notify affected users" -- while inform can sound a little more neutral and everyday -- "keep me informed," "inform the team." Both, though, share the same core claim relevant to this comparison: a completed act of telling someone something, which is the property that actually distinguishes them from flag.
That shared property is the one worth keeping in mind day to day: whichever of notify or inform you reach for, both report communication as done, while flag reports priority as marked -- a distinction worth checking whenever a process specifically requires proof that someone was told.
Practice scenarios
Practice using flag in situations like:
- deciding whether flagging something informally satisfies a formal notification requirement
- choosing notify/inform when the communication itself needs to be reported as complete
- choosing flag when you're marking priority ahead of a formal step
Useful practice phrases:
- "We notified HR of the policy change ahead of the rollout."
- "We flagged a gap in the new policy that HR should review."
- "Please inform the client of the delay by end of day."
Notify and inform report a completed act; flag marks a priority.
Don't let one quietly substitute for the other when a process requires the completed act specifically.
