processmost

Processmost is a concept used in process mining and workflow analysis to denote the most representative sequence of activities observed in a process, derived from event logs. It captures the dominant variant of a process—the path that occurs most frequently across observed executions.

Calculation involves collecting traces from event data, normalizing them into comparable sequences, and tallying their frequencies. The processmost is the single trace with the highest count. In practice, when multiple variants share the same maximum frequency, all such variants may be reported as processmost variants, or a tie-breaking rule is applied. Some approaches compute a probabilistic processmost by assigning weights to steps and selecting the path with the highest cumulative weight.

Applications include summarizing typical workflows, identifying standard operating procedures, benchmarking performance, and highlighting deviations for compliance or improvement initiatives. It is often used as a baseline for process improvement, training, and simulation.

Limitations include sensitivity to data quality and sampling bias, potential to ignore rare but important paths, and a risk of conflating popularity with optimality. The processmost reflects what has been observed, not necessarily what is ideal or most efficient.
