In OMG’s BPMN usage guidance and common practice, BPMN models are often discussed inthree levels of detail:
Level 1 – Descriptive (non-technical) modeling
Level 2 – Analytical (detailed but still platform-independent) modeling
Level 3 – Executable (implementation-ready) modeling
Descriptive modeling(Level 1) deliberately uses asmall, business-oriented subset of BPMN symbols. It avoids technical execution attributes and is meant primarily fordocumentation and communication among business stakeholdersacross the organization: managers, business analysts, and subject-matter experts.
Because it is simple, easy to read, and does not assume knowledge of execution semantics or tooling, it isthe easiest level to communicate across the organization.
The other options do not match OMG’s three levels:
Event modelingandvisual modelingare not defined as standard BPMN levels.
Executable modelingis Level 3, aimed at implementation, and isnotthe easiest for broad communication because it introduces technical details (data, error handling, engine-specific attributes).
Therefore, the correct answer isdescriptive modeling.
