activity Instance and Human Resource count Ratio

View in library docs
IHRR(g)\mathit{IHRR}(g)
Dimension:
Flexibility
Granularity:
Group of cases

Description

Ratio between the number of times that any activity is instantiated in a group of cases, and the number of human resources that are involved in the execution of a group of cases.

Potential use

Process where several human resources are involved.

Assumptions

Minimizing the number of human resources involved in the execution of a group of cases is desirable.

Desired Value:

MAXIMIZE

Equations

Formula for practitioners

I(g)HR(g)\frac{\mathit{I}(g)}{\mathit{HR}(g)}

I(g)\mathit{I}(g) returns the total number of activity instances in group gg.
HR(g)\mathit{HR}(g) returns the number of unique human resources involved in group gg.

Formal Definition

I(g)HR(g)\frac{\mathit{I}(g)}{\mathit{HR}(g)}
