Outcome units associated with an activity instance, measured as the sum of all values among the events of the activity instance.

Process where the outcome of activity instances can be measured.

Maximizing outcome unit count is desirable.

Formula for practitioners

$\begin{cases} \#^{}_{\mathit{unt}}(\mathit{str}(i)) + \#^{}_{\mathit{unt}}(\mathit{cpl}(i)) & \mathit{if \ } \#^{}_{\mathit{unt}}(\mathit{cpl}(i)) \neq undefined \land \\ & \#^{}_{\mathit{unt}}(\mathit{str}(i)) \neq undefined \\ undefined & \mathit{if \ } \#^{}_{\mathit{unt}}(\ \mathit{cpl}(i)) = undefined \lor \#^{}_{\mathit{unt}}(\mathit{str}(i)) = undefined \\ \end{cases}$

$\#^{}_{\mathit{unt}}$ returns the outcome unit count associated with an event.
$\mathit{str}(i)$ returns the start event of activity instance $i$.
$\mathit{cpl}(i)$ returns the completion event of activity instance $i$.
