Result Interpretation

Requirements Traceability Gap Index calculator computes Traceability Gap Index in % using the defined engineering formula and the input values provided. Traceability Gap Index is expressed in %. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Total Number of Requirements = 50
  • Number of Traced Requirements = 45

Expected Result:

  • Traceability Gap Index = 10

Engineering Interpretation:

Under the given input conditions, the calculated result is: Traceability Gap Index = 10 %.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

traceability gap index = (1 - (number of traced requirements / total number of requirements)) * 100
