The Black-Box Problem in BPMN
The engine has the knowledge. The task cannot reach it.
BPMN Process Engine — runtime knowledge available, but not delivered to the task
Instance History
what prior tasks decided
Audit Log
10,000 similar prior cases
Semantic Lineage
how each value was derived
Peer-Task State
what siblings are doing now
Goal Context
what this case is trying to achieve
Preference Weights
organizational trade-off guidance
Policy / Ontology Version
rules in effect right now
External Context
live signal from outside
no access path from task to runtime
BPMN Service Task
sees only its input map
Input Variables
a few values, no context
Without a uniform delivery mechanism, every concern outside the input map is either hand-wired into the diagram or lost.
