Non-Automated activity Instance count

\mathit{NAutI}(c)

Dimension:

Quality

Granularity:

Case

Description

Number of times that a non-automated activity is instantiated in a case.

Potential use

Event log that contains automated activities.

Assumptions

Non-automated activities are prone to errors, which reduces the quality of the process.

Desired Value:

MINIMIZE

Formula for practitioners

$\displaystyle \sum_{i \in \mathit{inst}(c)} \begin{cases} 1 & \text{if } \mathit{act}(i) \notin \mathit{Autl} \\ 0 & \text{otherwise} \end{cases}$

$\mathit{inst}(c)$ returns the set of all activity instances in case $c$ .
$\mathit{act}(i)$ returns the activity of activity instance $i$ .
$\mathit{Autl}$ returns the set of automated activities.

Formal Definition

$|\{i \in \mathit{inst}(c) \mid \mathit{act}(i) \notin \mathit{Autl}\}|$
