Generating code from diagrams is only useful if the diagrams are internally consistent. Validation is the “compile step” that catches issues early—before they become broken scaffolds.
What to validate before generation
- Naming consistency: duplicates, invalid identifiers, inconsistent casing
- Relationships: orphaned links, contradictory direction/ownership
- Behavior: incomplete workflows, missing transitions in state machines
- Critical flows: sequence diagrams referencing classes/fields that don’t exist
Why it matters
Skipping validation tends to produce scaffolds that fail later:
- Broken endpoints and missing DTOs
- Missing fields and mismatched names
- Baselines that don’t run end-to-end
A practical workflow
- Describe the system
- Generate/adjust UML views
- Validate (fix issues)
- Generate a runnable baseline
- Iterate
