Support Backlog Age: Calculate the weighted average age of unresolved support cases.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Support Backlog Age to answer this question: calculate the weighted average age of unresolved support cases? Enter Open support cases, Total open case-days, Cases older than target, and 1 other input; the calculator shows Average support backlog age. Try changing one number and watch what happens to Average support backlog age. The answer tells you Average support backlog age.
Age 15Explain it to a 15-year-oldConnect it to the formula
Segment by priority because a low average can conceal a small number of severely overdue critical cases. The rule is Average backlog age = total open case-days ÷ open cases. Its input values are Open support cases, Total open case-days, Cases older than target, Target resolution age in days, and the main result is Average support backlog age. Try changing one number and watch what happens to Average support backlog age.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Average backlog age = total open case-days ÷ open cases, evaluated from Open support cases, Total open case-days, Cases older than target, Target resolution age in days to produce Average support backlog age. Segment by priority because a low average can conceal a small number of severely overdue critical cases. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Calculate the weighted average age of unresolved support cases.
Why the business model works
Segment by priority because a low average can conceal a small number of severely overdue critical cases.
Inputs and operating assumptions
This model uses Open support cases, Total open case-days, Cases older than target, Target resolution age in days. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Average backlog age = total open case-days ÷ open cases
What the calculator produces
The primary output is Average support backlog age; it also exposes Cases older than target, Average age relative to target. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
