Waiting is experienced differently before and after engagement begins. Decide whether measurement includes pre-visit delays, lobby queues, or only time until first professional contact. Align with patient or customer perception, not convenience, because alignment increases trust, improves behavior change, and keeps improvement conversations grounded in reality.
Urgent and routine demand cannot share a single benchmark. Break out by acuity, age, language, mobility, referral source, and digital access. Segmentation reveals inequities and guides tailored fixes, like dedicated windows, interpreters, or parallel workflows, preventing well-intentioned changes from worsening access for vulnerable groups.
Phone trees, portals, and hallways hold invisible lines. Instrument callbacks, chat handoffs, and triage decisions so hidden delays surface in reports. When backlogs move offstage, leaders mistakenly believe demand shrank. Making the unseen visible protects fairness, safety, and morale during stressful periods.
