It provides an overview of the operations in the organization, eases the identification of processes and facilitates the communication across departments. Switzerland has defined a unified cartography for E-Government Services (eCH-0145). In this work, we discuss advantages and disadvantages of this cartography by comparing it to related work and applying it to map the processes of a Swiss canton in a proof-of-concept field study. Then, inspired from related work, we introduce the matrix cartography based on a meta-process describing E-Government Services. We provide initial evidence that the matrix cartography can be used as an alternative to eCH-0145. Future work will include further confirming the suitability of the matrix cartography in collaboration with Swiss public administrations.enText/Conference Paper1617-5468
