Data Center & Infrastructure Equipment Manufacturing worked example

Data Center Product Ramp at 7.2% learning and change allowance: a worked example

This worked example runs the data center product ramp numbers for a tougher week than the baseline: 7.2% learning and change allowance instead of the typical 10%. Estimate labor hours required to ramp a new rack, power, cooling, or modular infrastructure product into production.

The inputs for this scenario

  • Ramp tasks or build steps: 120 tasks (held at the documented default)
  • Ramp task completion pace: 12 tasks / hr (held at the documented default)
  • Learning and change allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base product ramp hours = ramp tasks or build steps รท ramp task completion pace.
  • Required product ramp hours works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base product ramp hours works out to 10 hr at these inputs.
  • Learning and change allowance works out to 7.2 % at these inputs.
  • Ramp task completion pace works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where learning and change allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • Use it during new-product introduction planning, pilot-build scheduling, and when committing a first-article delivery date for a new equipment design. 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

  • Required product ramp hours: 10.72 hr (headline result)
  • Base product ramp hours: 10 hr
  • Learning and change allowance: 7.2 %
  • Ramp task completion pace: 12 pieces / min
