A universal system for how work gets done
Operator 13:
Bridge Start
Bridge Start represents the intentional transition from the current sequence into a separate, linked flow that will later return to the main path. It marks the point where execution temporarily shifts to another defined process while preserving continuity and context. Bridge Start does not perform work itself; it governs structured movement across process boundaries. Without clearly defining a Bridge Start, workflows can lose traceability, become fragmented, or fail to reconnect cleanly with the originating sequence.
Plain-English Definition
Bridge Start marks the point where a parallel sequence begins. It allows one or more sequences to proceed independently while the main route continues or pauses.
What Bridge Start Does
Bridge Start introduces controlled parallelism. It explicitly declares that another sequence of steps is running alongside the primary route.
What Bridge Start Is Not
Bridge Start is not branching due to decision. It does not imply conditional choice. It does not complete the parallel work.
Core Characteristics
-
A parallel sequence is initiated
-
The main route may continue or wait
-
Completion is handled by Bridge Return
Examples Across Contexts
-
Directed (designed process): Initiating a background task while primary work proceeds
-
Observed (descriptive): A secondary activity runs alongside core operations
-
Natural phenomena: Concurrent processes begin from a shared initiating condition
How Bridge Start Works with Other Operators
Bridge Start must be paired with Bridge Return. Between them exists a self-contained parallel sequence. Repeat, Wait, or Process may occur within the bridge.
Common Mistakes
-
Forgetting to rejoin with Bridge Return
-
Using Bridge Start for branching logic
-
Allowing parallel work to leak into the main route
Key Questions to Identify Bridge Start
-
Does this work occur in parallel?
-
Is the main route not blocked by this work?
-
Will the work rejoin later?
Things to Remember
Parallel work must be explicitly bounded.
Canonical Definition
Bridge Start declares the beginning of a parallel sequence.
