Results

Precision: {{ results.precision.toFixed(1) }}%

Accuracy: {{ results.accuracy.toFixed(1) }}%

Optimistic: {{ results.optimistic }} h

Most Likely: {{ results.mostLikely }} h

Pessimistic: {{ results.pessimistic }} h

Expected (PERT): {{ results.expected.toFixed(1) }} h

Inputs:

Expertise (E): How skilled the team is with this type of work.
Process Familiarity (F): How familiar the team is with the workflow and tools.
Execution Frequency (X): How often this type of work has been done before.
Clarity of Done (C): How clearly the definition of “done” is defined.

Calculations:

Precision is based on Familiarity, Frequency, and Clarity.
Accuracy is based on Expertise and Clarity.
These values shape a range: Optimistic → Most Likely → Pessimistic.
Expected (PERT) is a weighted average: (Optimistic + 4×Most Likely + Pessimistic) ÷ 6.
