Start with a stable reporting definition before automating collection and transformation. Document ownership of the inputs, calculation and final output.
Before you begin
Use fictional or properly licensed data with a documented question, units and column definitions.
Work through the idea
State the decision or learning question first. Keep raw inputs separate from derived tables and document filters, exclusions and calculations. Check at least one result manually and record a limitation. Communicate what the evidence supports without inventing business outcomes or exposing personal information.
- Map the manual workflow
- Identify repeatable steps
- Separate calculation from distribution
Practice task
Design a fictional monthly reporting process that checks source totals before producing charts.
Check your result
Explain how corrections are rerun and how the audience knows the report's period and version.
A mistake to avoid
Do not automate an ambiguous measure and assume scheduling makes it reliable.
Keep a review note
Save the inputs or scenario, your reasoning and the result you checked. Explain one assumption and one case that needs more work. Revise the exercise after feedback and distinguish what you demonstrated from what remains untested.
