Executive support service levels 2026: what to measure

Executive support service levels 2026

An executive support service level is a defined expectation for what happens after work enters the support queue. It might cover triage, scheduling, preparation, escalation, or closure. It should not be reduced to a single promise such as “reply within an hour.” The right measure depends on the request, the authority available to the assistant, and the risk of a wrong action.

Methodology and limitations

This review uses current institutional reports, government guidance, and workplace studies available on August 6, 2026. The sources measure different populations and outcomes, so they are not pooled. Microsoft measures interruptions, the email study describes a small interview sample, and IC3 records complaints. None supplies an executive-specific service-level average. The framework below uses those sources to define local measures rather than claim a population benchmark.

Key statistics

Source	Finding	Limitation
Microsoft Work Trend Index 2025	275 daily interruptions by meeting, email, or chat were reported for workers in the study	It does not isolate executive support or email
You’ve got mail study	28 usable interview responses reported 64 received work emails on a typical day	A small, non-executive sample is not a quota
Russell et al. systematic review	62 empirical papers were synthesized on work-email activity	The review does not set response targets
2025 IC3 report	24,768 business-email-compromise complaints were recorded	Complaints are not total incident prevalence

The four measures a support team needs

Track time to classification, time to a decision-ready brief, time to final response, and time to closure. Classification can mean routing, drafting, scheduling, or escalation. A decision-ready brief means the executive has the context and options needed to decide. Closure means the owner and next action are recorded. These are different events and should not share one clock.

Set targets by category. Routine scheduling may be handled in the next agreed triage window. A board, legal, financial, personnel, or crisis item needs a named escalation path. Requests to change payment details or share credentials require independent verification before speed. The CISA MFA guidance and FTC small-business security guidance support that boundary.

A two-week baseline

Record arrival time, category, owner, classification time, preparation time, final response time, and whether the item was reclassified as urgent. Do not copy sensitive message content into the measurement sheet. Review medians, oldest open items, misses by category, and work completed outside agreed hours. Change one rule at a time, then compare the same fields after two weeks.

FAQ

What is a reasonable executive support response time?

There is no universal research-backed number. Define the action, category, working hours, and escalation rule first.

Should every request have the same service level?

No. Risk, decision authority, and urgency differ. A single inbox-wide target hides those differences.

What should assistants report weekly?

Report volume, median classification time, decision-ready preparation time, aging, misses, escalations, and after-hours spillover.
