Operational spreadsheet consulting for small businesses
A practical checklist for identifying fragile spreadsheets before they become operational risks.
Many organisations rely heavily on spreadsheets for reporting, planning, and operational workflows.
Over time these files often become difficult to maintain, slow to update, and risky to depend on.
This checklist helps identify warning signs that a spreadsheet may be fragile.
• formulas referencing inconsistent or shifting ranges
• calculations mixed with raw data
• manual copy-paste steps in regular processes
• hidden dependencies between sheets
• multiple versions circulating by email
• logic embedded in cell formulas rather than structure
• nested formulas that are difficult to understand
• hard-coded values inside formulas
• unclear ownership or maintenance responsibility
• inconsistent column structures
• missing validation or data controls
• no separation between input, processing, and output
• formulas referencing entire columns unnecessarily
• lack of documentation explaining how the model works
Fragile spreadsheets increase operational risk.
They slow down reporting, introduce errors, and make processes dependent on specific individuals who understand how the file works.
Identifying fragility early allows teams to stabilise the structure before those risks grow.
