i'm currently writing my diploma-thesis, which is a SWOT-Analysis including a redesign of the VDA5004, the pickup-process defined by the association of the german automotive industry.

Therefor, two questiones came up:

1. On which basis is the VDA5004 created? How is this type of visualization called?
 LINK to the process: http://www.vda.de/de/downloads/109/?PHPSESSID=mr4i5nuiacgp7cga9eu6ib3g34


2. What should i use for myself, if i want to visualize parts of this process or (if i want to redesign the process) including IT-Objects and process owner?

Makes it sense to take an extendedEPC (in german eEPK) or the BPMN or something else ?


thank you in advance,
