Every Lean optimization path typically starts with the mapping of a process, to identify criticalities and wastes embedded in manufacturing processes. Value Stream Mapping (VSM) represents the main and most suitable Lean technique to this purpose, thanks to its simplicity and immediacy residing in its visual effectiveness. Originally designed as a “draw by hand” mapping technique, VSM is moving on digital platforms; different software has in fact been developed over the last few years, each with its own functionalities and characteristics, reason why a software may not be always valid, but useful only within certain contexts. According to a classification of software based on mapping, analytical and collaborative functionalities, crucial aspects for a successful VSM application, the paper aims to depict, through a benchmark analysis, the current situation regarding VSM software and, therefore, serve as a reference model to orient manufacturing companies towards best suited VSM applications.
