Ratio between the number of activity pairs where one is instantiated directly after the other in a group of cases, and the number of activities that occur in a group of cases.

Process where several distinct directly-follows relations can occur.

A greater number of directly-follows relations is desirable, as it implies a greater capability to address unexpected situations.

Formula for practitioners

$\frac{\mathit{DFR}(g)}{\mathit{A}(g)}$

$\mathit{DFR}(g)$ returns the number of unique Directly-Follows Relations (DFR) in group $g$.
$\mathit{A}(g)$ returns the number of unique activities in group $g$.
