Choose a bounded original dataset
Use fictional activity and factor values or properly sourced public records with explicit coverage. Do not put employer or client records in a public portfolio. A small synthetic dataset can show the analytical method without claiming company assurance.
Link the practical outputs
| Artifact | Skill shown |
|---|---|
| Factor-source log | Version and unit discipline |
| Boundary record | Coverage and classification questions |
| Equivalent-unit check | Independent arithmetic |
| Amount/intensity comparison | Interpretation of different metrics |
| Limitations note | Evidence-sensitive conclusions |
Include one reproducible data issue
A MWh/kWh mismatch, missing record or denominator-scale error can show how you identify and correct a problem. Preserve the original definition and corrected calculation rather than simply overwriting the value.
Keep credentials and outcomes separate
Completing the exercise does not provide a professional designation or certify an inventory. Explain which conclusions follow from the example and which require published-method or entity-specific evidence.
