The cost of the unthreaded stream
Enterprise chat tools such as Slack and Microsoft Teams were built to replace slow internal email chains. Yet without strict channel architecture, they recreate the worst aspects of an open-plan office—except the interruptions follow workers across time zones and onto mobile screens at night.
From a handoff perspective, real-time chat has a structural flaw: chronology overrides importance. A crucial product scope change agreed upon at 10:15 AM scrolls out of view by 11:00 AM under a wave of deployment notifications and casual banter. Operations leads must configure their tools so ephemeral conversation never serves as the system of record.
