Define “response” before timing it
An acknowledgement says a request arrived. A meaningful response answers the request or asks for the information needed to move it forward. A completed resolution is another milestone again.
Choose the event you want to improve before comparing times. A faster acknowledgement does not necessarily mean a faster useful answer. Document whether your measure counts elapsed time or only staffed business hours.
Work through one example
Fictional example: an inquiry arrives Friday at 4:50 p.m. An automatic acknowledgement goes out at 4:51 p.m. The office closes at 5 p.m., opens Monday at 9 a.m., and a team member gives a useful reply at 9:20 a.m.
The acknowledgement took one minute. The meaningful reply took 64 hours and 30 minutes of elapsed time, or 30 staffed minutes under that schedule. Both measures can be correct; they answer different questions. State the schedule, time zone and any excluded holidays beside the result.
Calculate a single staffed interval
This small calculator is for two times on the same staffed day. It does not exclude breaks, holidays or overnight hours. Nothing entered is sent or saved.
Describe the missing records
If you can time only eight of ten inquiries, report “eight timed records; two missing response evidence.” Do not assign zero minutes to missing data or silently remove unanswered requests. Identify duplicates and use the same counting rule across periods.
For a small set, show the individual intervals and the count. A median can describe a typical recorded wait; it does not describe the requests you could not measure. Compare like periods and the same definition before interpreting a change.
Turn the result into a decision
Look for a specific reason a request waited: coverage, unclear ownership, missing information or capacity. Choose one change you can test, then use the same measurement rules next time.
There is no universal response-time promise in this worksheet. Set a realistic service expectation for your business, explain availability accurately and keep the underlying records available to the people reviewing the result.
