Business Process Analysis: rules

Objective: process de-composition Criteria

o Task homogeneityo Spatial frontiers (re-group tasks related to the same place, i.e. a cashier's

office or an organization’s divisiono Interaction with third systems (see next slide)o Re-usable sub-processes / activitieso End / start events

Process Modeling: processes and sub-processes

Separate groups of related tasks (sub-processes) from stand-alone tasks

Ok, but who starts the process?

Petros KAVASSALIS <petros@cfp.mit.edu> 10

The process has started but it should wait somewhere…

Petros KAVASSALIS <petros@cfp.mit.edu> 11

… After waiting for a while, it goes further and ends… another process starts
