Battery Pack Assembly Takt Cost at 110% program share of takt cost: a worked example

Push program share of takt cost up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a battery pack assembler needs to cost a takt-time scenario before committing operators, fixtures, or overtime

The inputs for this scenario

  • Planned battery packs: 420 packs (unchanged)
  • Cost per pack takt slot: 185 $ / pack (unchanged)
  • Program share of takt cost: 110 % (raised for this scenario; the documented default is 100)
  • Fixed pack launch/setup cost: 6,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable pack takt cost = planned battery packs × cost per pack takt slot × program share) to the inputs above produces each figure below.
  • At this operating point the engine returns 91,970 $ for total pack takt cost, the number this scenario is built around.
  • At this operating point the engine returns 219 $ / pack for cost per planned pack.
  • At this operating point the engine returns 85,470 $ for variable pack takt cost.
  • At this operating point the engine returns 6,500 $ for fixed pack launch/setup cost.

How this compares with the baseline

  • Against the tool's baseline example, where program share of takt cost sits at 100% and the headline result is 84,200 $, this scenario comes in 9.23% above the baseline at 91,970 $.
  • It computes the total takt-paced cost to assemble a planned batch of battery packs, splitting variable takt slot cost (scaled by program share) from fixed launch and setup cost. 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 pack takt cost: 91,970 $ (headline result)
  • Cost per planned pack: 219 $ / pack
  • Variable pack takt cost: 85,470 $
  • Fixed pack launch/setup cost: 6,500 $
