Operating brief
Recovery systems
Backlog recovery planning starts by separating capacity from throughput.
Rated capacity describes a system under stated conditions. A credible recovery plan starts with the output the operation can actually realize—then compares it with the work still arriving.

Key takeaways
Rated capacity is a ceiling; recovery depends on effective throughput after utilization, quality, aging, and downtime losses.
A queue recovers only when effective output remains above incoming demand long enough to reach a defined control threshold.
A credible commitment makes every material assumption, stress case, and decision owner visible before a date is published.
A capacity number is not a recovery plan.
Queues recover only when effective output remains above incoming demand long enough to reach a defined control threshold. Teams often begin with theoretical capacity, but it ignores utilization loss, rework, aged-work complexity, downtime, and demand volatility. A date becomes credible only after those losses are visible.
Operating equation
Effective throughput = rated capacity × utilization × productivity × quality × aging factor + surge
Three equations turn a queue into a decision.
Net backlog burn = effective throughput − weekly inbound. Weeks to threshold = (current backlog − control threshold) ÷ net burn. Required throughput = weekly inbound + backlog gap ÷ target weeks.
Pressure-test the promise before publishing the date.
Define the queue; choose the control threshold; use demonstrated output; separate temporary and structural capacity; stress demand and execution; name the decision owner.
Decision boundary
The core equations are deterministic. The companion calculator adds a reproducible scenario simulation, but neither forecasts demand, discovers constraints, models queue congestion, optimizes a workforce, or validates source data. Use them to expose assumptions and define the operating evidence required before action.
