Purpose and scope
What this schedule planner builds
Sequence review stages and determine a modeled approval completion time.
The Approval Turnaround Timeline builds ordered blocks from Submitted, Approval stages, Clock, and Warning lead time (hours); Inspect Warning lead time (hours) at each handoff.
Instructions
How to use this calculator
Enter submission time, review stages with hours, elapsed or business clock, and an internal warning lead.
- Set Submitted and Approval stages as the Approval Turnaround Timeline planning boundary.
- Set Clock and Warning lead time (hours) from the current source record.
- Build the Approval Turnaround Timeline blocks and inspect each Warning lead time (hours) transition.
- Change one uncertain Approval Turnaround Timeline constraint, then compare the revised plan.
Practical use
Recommended workflow
Confirm stage owners, publish expected handoff times, and escalate at the earlier warning checkpoint.
The SLA Deadline Calculator covers the related step of helping you calculate response or resolution deadlines using elapsed or business-hour rules.
Calculation
Method used
Stages advance sequentially. Elapsed mode runs continuously while business mode advances through the modeled weekday service window.
The Approval Turnaround Timeline separates Submitted, Approval stages, and Clock into stages; compare Warning lead time (hours) with the anchor before changing duration.
Calculation method last reviewed: June 21, 2026.
Worked scenario
Example calculation
Compare the Approval Turnaround Timeline stage order with Submitted and Approval stages; if spans diverge, inspect Warning lead time (hours) first.
Visual audit
Reading the schedule blocks
The Approval Turnaround Timeline schedule builds blocks from Submitted, Approval stages, Clock, and Warning lead time (hours). Inspect each Warning lead time (hours) handoff, then compare Approval Turnaround Timeline overlap, setup time, and deadline fit.
Boundaries
Important edge cases and limitations
Reviewer availability, holidays, rework, parallel reviews, priority queues, and custom service hours are excluded.
Change the affected Approval Turnaround Timeline block when Warning lead time (hours) is excluded, then regenerate downstream timing.
Interpretation
Reviewing the generated schedule
The final timestamp is a planning expectation. Each intermediate handoff is equally important for escalation.
Keep Warning lead time (hours) between the first and final Approval Turnaround Timeline blocks; change intermediate stages only when Warning lead time (hours) from the source record allows it.
After the Approval Turnaround Timeline, open the Document Review Cycle Planner to schedule reviewers, revision rounds, handoffs, and final completion.
Input audit
Checklist for this calculation
- Inspect the Approval Turnaround Timeline start in Submitted and Approval stages.
- Compare every Approval Turnaround Timeline duration with the Warning lead time (hours) unit.
- Inspect Warning lead time (hours) handoffs for gaps and setup time.
- Keep the final Approval Turnaround Timeline block inside its boundary.
Questions
Frequently asked questions
Can reviewers work in parallel in this calculator?
No. The displayed chain is sequential; genuinely parallel reviews should be modeled as separate branches.
When is a previous approval turnaround timeline output no longer comparable?
Another Approval Turnaround Timeline run is warranted when Submitted moves, Warning lead time (hours) is redefined, or the governing calculation rule changes.
Which convention should Submitted use in the
Submitted establishes the Approval Turnaround Timeline starting constraint and Warning lead time (hours) changes the available schedule. Compare both Approval Turnaround Timeline fields with the same source record.
