Aglet

Investigate quiet-hours expectations across time zones

An investigation should explain what happens when an event lands inside a quiet window and when the person changes time zone or urgency. Replay representative schedules, compare in-app and external states, and keep platform summary behavior separate from the product’s own timing contract.

Build a useful investigation brief

  1. Build the timing matrix

    List event time, account time zone, user schedule, urgency, channel, delivery state, in-app visibility, and next available action. Include boundary minutes around quiet hours and a normal-hours control. Record daylight or travel assumptions explicitly.

  2. Vary one timing factor

    Hold event and channel fixed while changing schedule, time zone, or urgency. Compare delivery, in-app status, copy, and resume behavior. Record a delayed but available event and a truly absent event so the investigation does not merge them.

  3. Write the timing brief

    State first divergence, affected event class, visibility promise, and competing explanations. Recommend one bounded schedule, status, or copy experiment with a pass condition. Do not claim the system delivered or suppressed a notification when the platform boundary is unknown.

What to carry forward

The investigation is complete when delayed events, available events, and missing evidence have reproducible boundaries across selected time zones. Stop with one timing experiment. Keep platform-controlled presentation and app-controlled history as separate parts of the brief.
