Data Center & Infrastructure Equipment Manufacturing worked example

Server Rack Assembly Cost at 92% build scope completed in-house: a worked example

Push build scope completed in-house up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when server rack assembly cost in data center and infrastructure equipment manufacturing is being put through a data center and infrastructure equipment manufacturing weighted-cost review.

The inputs for this scenario

  • Rack or cabinet builds: 100 racks (unchanged)
  • Assembly labor and parts cost per rack: 45 $ / rack (unchanged)
  • Build scope completed in-house: 92 % (raised for this scenario; the documented default is 80)
  • Fixed setup and engineering cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Rack assembly build cost = rack or cabinet builds × assembly cost per rack × build scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total rack assembly cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for assembly cost per rack.
  • At this operating point the engine returns 4,140 $ for rack assembly build cost.
  • At this operating point the engine returns 250 $ for fixed setup and engineering cost.

How this compares with the baseline

  • Against the tool's baseline example, where build scope completed in-house sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes total rack assembly cost by multiplying rack count by per-rack cost and your in-house build scope, then adding fixed setup and engineering. 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.

Results at a glance

  • Total rack assembly cost: 4,390 $ (headline result)
  • Assembly cost per rack: 43.9 $ / piece
  • Rack assembly build cost: 4,140 $
  • Fixed setup and engineering cost: 250 $
