Coffee, Tea, Roasting & Dry Goods Processing worked example

Line OEE at 63% speed performance factor: a worked example in coffee, tea, roasting & dry goods processing

Here is what the math looks like when conditions slip. We hold every other input steady and drop speed performance factor to 63%, then walk the calculation through step by step. Estimate line OEE-style availability from operating time, planned time, performance factor, and quality factor.

The inputs for this scenario

  • Actual line operating time: 6.6 hr (held at the documented default)
  • Planned production time: 8 hr (held at the documented default)
  • Speed performance factor: 63 % (the input this scenario stresses; the baseline uses 88)
  • Quality release factor: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base availability = line operating time ÷ planned production time × 100.
  • line oee works out to 50.42 % at these inputs, and this is the headline figure for the scenario.
  • base packaging or roasting availability works out to 82.5 % at these inputs.
  • speed performance factor works out to 63 % at these inputs.
  • quality release factor works out to 97 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where speed performance factor sits at 88% and the headline result is 70.42 %, this scenario comes in 28.41% below the baseline at 50.42 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to speed performance factor, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It is only as good as your loss data — if planned time excludes scheduled stops inconsistently, or performance and quality are estimated rather than measured, the OEE will mislead.
