Spreadsheet QualitySpreadsheet Design Concepts Series
Fan in / fan out
- Low fan in - a 'unit' (cell/worksheet/VBA routine) depends on only a few other units
- Good because it minimises dependencies and reduces complexity
- High fan out - a 'unit' (cell/worksheet/VBA routine) is used by many others
- Good because it minimises duplication
- Example: putting VAT (Sales tax) rates in their own cells, and referring there in calculations
- Example: calculating an offset once and using the result many times
