phasesstart

Phasesstart is a term used in process modeling and software engineering to denote the moment a particular phase begins within a phased lifecycle. It functions as an event label or marker that signals the activation of a phase, such as design, implementation, testing, or deployment, and is used to coordinate activities across teams and systems.

In workflow engines, manufacturing automation, and simulation models, phasesstart triggers tasks, allocates resources, initializes data structures, and records timing information. It helps ensure that dependent steps do not start until the preceding phase has reached its start condition, and it can be logged for audit trails and performance analysis.

Technically, phasesstart is commonly implemented as an event in a state machine or as a timestamped entry in a phase ledger. It may be parameterized with identifiers such as phase_id, project_id, or process_id to enable cross-cutting tracking of phases across multiple subsystems.

Because there is no universally adopted standard for this term, naming conventions vary. Some tools prefer PhaseStart, phases_start, or start_of_phase. Documentation generally treats phasesstart as an alias for the initiation event of a phase and describes its role in coordinating lifecycle activities.
