This article investigates whether an existing process modelling notation - the Parallel Activity Specification Scheme (PASS) - can support the digitalisation of manufacturing processes. In particular, four aspects are examined that have previously been claimed to be benefits of the PASS notation: ease of modelling, distributed modelling, incremental change, and IT integration. This is done by analysing three digital transformation projects in the manufacturing industry. The projects included the analysis and improvement of cross-department value streams, the introduction of Automated Guided Vehicles (AGVs) on the shopfloor, and the specification of a new Manufacturing Execution System (MES). The ways in which PASS was used and whether it was able to provide its claimed benefits are presented and analysed.
