Cutoffs define eligibility
An after-cutoff order usually enters a later service window. Treating it as late against the earlier window misstates SLA attainment.
Sustainable capacity matters
Theoretical peak throughput should be adjusted for the entered sustainable factor and known capacity losses.
Frequently Asked Questions
What is a fulfillment SLA?
An operational promise defining when an eligible order must reach a stated fulfillment event.
How does a cutoff work?
Orders after the cutoff generally move to the next configured business-day service window.
Does daily capacity equal SLA performance?
No. Daily totals can hide late arrivals, pickups, deadlines, backlog, and intraday bottlenecks.
How should weekends and holidays be treated?
Configure operating weekdays and explicit closure dates. The tool does not invent a holiday calendar.
What is sustainable capacity?
Entered gross capacity adjusted by the user-defined sustainable factor and explicit loss percentage.
Is order data uploaded?
No. CSV content and operational assumptions remain in this browser.
