Demand Ramp Planner at 65% expected line uptime during ramp: a worked example in smart home & consumer iot hardware

This worked example runs the demand ramp planner numbers for a tougher week than the baseline: 65% expected line uptime during ramp instead of the typical 90%. Estimate demand ramp planner for smart home and consumer IoT hardware using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Units produced per production cycle: 4 units / cycle (held at the documented default)
  • Scheduled production cycles in the ramp window: 480 cycles (held at the documented default)
  • Expected line uptime during ramp: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass yield on finished devices: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross demand ramp planner capacity = demand ramp planner output per cycle × available demand ramp planner cycles.
  • Good demand ramp planner capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross demand ramp planner capacity works out to 1,920 units at these inputs.
  • Demand ramp planner downtime loss works out to 672 units at these inputs.
  • Demand ramp planner yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected line uptime during ramp sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • Use it when committing volume for a product launch or ramp, sizing a build plan against a demand forecast, or negotiating capacity with a contract manufacturer. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Good demand ramp planner capacity: 1,211 units (headline result)
  • Gross demand ramp planner capacity: 1,920 units
  • Demand ramp planner downtime loss: 672 units
  • Demand ramp planner yield loss: 37.44 units

Run it with your numbers

  • To rerun this with your own numbers, open the live Demand Ramp Planner calculator, set expected line uptime during ramp to your actual value, and adjust the remaining inputs to match your operation.
