Lab Equipment & Scientific Instrument Manufacturing worked example

Instrument Assembly Labor at 23% staging and documentation allowance: a worked example in lab equipment & scientific instrument manufacturing

Push staging and documentation allowance up to 23% and the picture changes. This example computes every intermediate figure at that operating point. Use when planning production schedules for instrument builds, quoting delivery dates for customer orders, or estimating assembly labor cost for a new product introduction. Common for spectrometers, chromatographs, microscopes, analyzers, and custom lab systems.

The inputs for this scenario

  • Instruments to assemble: 12 instruments (unchanged)
  • Assembly completion rate: 0.25 instruments / hr (unchanged)
  • Staging and documentation allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base assembly time = instruments to assemble / assembly completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 59.04 hr for scheduled assembly labor, the number this scenario is built around.
  • At this operating point the engine returns 48 hr for base assembly time.
  • At this operating point the engine returns 23 % for staging and documentation allowance applied.
  • At this operating point the engine returns 0.25 pieces / min for assembly completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where staging and documentation allowance sits at 20% and the headline result is 57.6 hr, this scenario comes in 2.5% above the baseline at 59.04 hr.
  • It computes scheduled assembly labor hours by dividing instruments to assemble by the completion rate, then inflating that base time by a staging and documentation allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
