Successful outcome Unit Count

\mathit{SUC}\mathit{^{\times}}(c)

\mathit{\times} \in \{\mathit{sgl}, \mathit{sum}\}

Dimension:

Quality

Granularity:

Case

Description

Outcome units associated with all activity instances in a case, after deducting those that were unsuccessfully completed.

Potential use

Process where the outcome of activity instances, as well as whether they are successful or not, can be measured.

Assumptions

Maximizing the number of successful outcome units is desirable.

Desired Value:

MAXIMIZE

Equations

Formula for practitioners

$\sum _{i \in \mathit{inst}(c)} \mathit{SUC}(i)$

$\mathit{inst}(c)$ returns the set of all activity instances in case $c$ .
$\mathit{SUC}(i)$ returns the successful outcome unit count of activity instance $i$ .

Formal Definition

$\sum _{i \in \mathit{inst}(c)} \mathit{SUC}\mathit{^{\times}}(i)$
The $\mathit{\times}$ indicates that the PPI can take multiple forms, in this case, $\mathit{\times} \in \{\mathit{sgl}, \mathit{sum}\}$ . If $\mathit{\times} = \mathit{sgl}$ , then the function considers single events of activity instances for outcome unit calculations, i.e., it uses $\mathit{SUC}\mathit{^{sgl}}$ ; if $\mathit{\times} = \mathit{sum}$ , then the function considers the sum of all events of activity instances for outcome unit calculations, i.e., it uses $\mathit{SUC}\mathit{^{sum}}$ .
