Exercise 3: Why the Explicit "Resolved" Message Matters — Possible Solution ==================================================================== WHY THE EXPLICIT MESSAGE MATTERS ------------------------------ Per this chapter, "once resolved, an explicit 'this is now resolved' message matters just as much as the original 'we're investigating' one. People who were told about a problem need to be explicitly told it's over." The people who received the earlier updates were told there was a problem - without an equally explicit signal that the problem is over, they have no reliable way of knowing when it actually ended. WHAT GOES WRONG IF IT'S SKIPPED ------------------------------ Per this chapter, "a real fraction of them continue operating under the assumption it might still be happening (avoiding a feature, expecting delays) longer than necessary." Without an explicit all-clear, people who were told about the checkout failures might keep avoiding checkout, or keep warning others about it, or keep expecting delays, well after the fix has actually deployed - because nothing told them the situation had changed. WHY SILENTLY STOPPING UPDATES DOESN'T ACCOMPLISH THE SAME THING ------------------------------ Stopping updates after the fix is deployed leaves the audience in the same position silence created earlier in the incident (per this chapter's own opening point) - they have to guess what the absence of further news means, and per this chapter's own reasoning about silence, the likely guess isn't "it's fixed," it's ambiguity or continued concern. The 14:05-15:05 updates already established a pattern of expecting updates; simply stopping doesn't communicate resolution the way an explicit statement does. WHY THIS WORKS AS AN ANSWER ------------------------------ It explains specifically why an explicit resolution message is needed rather than assumed, names the concrete real-world consequence of skipping it (continued avoidance/expectation of the problem), and explains why silently stopping updates doesn't substitute for stating resolution directly.
