\mathit{IbyHR}(a, \mathit{hr})

Dimension:

Quality

Granularity:

Activity

Description

Number of times a specific human resource performs an activity in the event log.

Potential use

Process where individual performance of human resources is relevant.

Assumptions

Maximizing the number of activities conducted by the same human resource is desirable.

Desired Value:

MAXIMIZE

Formula for practitioners

$\displaystyle \sum_{i \in \mathit{inst}(a)} \begin{cases} 1 & \text{if } \mathit{hres}(i) = \mathit{hr} \\ 0 & \text{otherwise} \end{cases}$

$\mathit{inst}(a)$ returns the set of all instances of activity $a$ .
$\mathit{hres}(i)$ returns the human resource associated with activity instance $i$ .

Formal Definition

$|\{i \in \mathit{inst}(a) \mid \mathit{hres}(i) = \mathit{hr}\}|$
