Configured Valve Quote Time at 18% review, approval, and clarification overhead: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop review, approval, and clarification overhead to 18%, then walk the calculation through step by step. Estimate total engineering and sales hours to prepare quotes for configured (made-to-order) valve assemblies based on line items to quote, hours per line item, and review and approval overhead.

The inputs for this scenario

  • Configured valve line items to quote: 18 line items (held at the documented default)
  • Average engineering hours per line item: 1.5 hr / line item (held at the documented default)
  • Review, approval, and clarification overhead: 18 % (the input this scenario stresses; the baseline uses 25)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base quoting hours = line items x hours per line item.
  • Total configured valve quote time (hours) works out to 14.16 hr at these inputs, and this is the headline figure for the scenario.
  • Base quoting hours (technical work only) works out to 12 hr at these inputs.
  • Review and approval hours added works out to 18 % at these inputs.
  • Line items quoted per hour works out to 1.5 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where review, approval, and clarification overhead sits at 25% and the headline result is 15 hr, this scenario comes in 5.6% below the baseline at 14.16 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to review, approval, and clarification overhead, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a uniform average per line item, so a single severe-service or custom-trim item can blow the estimate if the mix is uneven.

Results at a glance

  • Total configured valve quote time (hours): 14.16 hr (headline result)
  • Base quoting hours (technical work only): 12 hr
  • Review and approval hours added: 18 %
  • Line items quoted per hour: 1.5 pieces / min
