Full guide: definition, formula, and benchmarksWhy User Activity Score matters for Slack users
Message count alone is a misleading measure of Slack engagement. A user who reads carefully, reacts thoughtfully, and replies in threads is more engaged than one who posts frequently but adds little value. A composite score captures the full range of engagement behaviours.
For Slack administrators, user activity scores segmented by department or role reveal adoption gaps and engagement variations. Low-scoring segments may need targeted onboarding, training, or cultural encouragement to participate more actively.

Platform Adoption Rate
CollaborationPlatform Adoption Rate = Active Users / Total Provisioned Users × 100
Platform Adoption Rate measures the percentage of organisation members who are actively using Slack - sending messages, reacting, or engaging with content - within a defined period. It distinguishes between accounts that exist and accounts that are genuinely adopted into daily workflows.
View metricNotification Engagement Rate
CollaborationNotification Engagement Rate = Notifications Acted On / Total Notifications × 100
