The Usage App ships ready to go. The work is establishing a regular review cadence and acting on what the dashboards show.

  1. Open the Lightning Usage App

    Setup, Quick Find, Lightning Usage. The app opens with the default dashboards.

  2. Review the EPT dashboard

    Sort pages by EPT descending. Anything above 5 seconds is a candidate for investigation.

  3. Investigate slow pages

    Open the slow page in Lightning App Builder. Inspect the components present; identify custom LWCs or heavy related lists.

  4. Run Salesforce Optimizer

    Setup, Optimizer, request a fresh report. Review the recommendations and prioritize the high-impact ones.

  5. Track Daily Active Users and Switcher Usage

    Monitor weekly. Drops in DAU or spikes in Switcher Usage signal user-experience problems that need attention.

  6. Report to executives quarterly

    Build a quarterly executive review using the Usage App dashboards. The data tells the platform-health story with no extra reporting work.

Gotchas
  • EPT measures real-world performance, not synthetic benchmarks. A page that benchmarks well in sandbox may have high EPT in production due to data volume or user-specific permissions.
  • The Usage App is a snapshot of recent activity, not real-time. Data refreshes daily; do not expect instant feedback after a change.
  • Switcher Usage is the canary metric for Lightning adoption problems. A user who switches back to Classic frequently is telling you something about Lightning UX.
  • Salesforce Optimizer is recommendation-only. The Optimizer does not change anything; the admin still has to act on the recommendations.
