“The use of an Excel spreadsheet file to track and report financial performance for a NZ$28bn expenditure organisation raises significant concerns, particularly when other more appropriate systems are present on the IT landscape.”

Health New Zealand runs NZ$28 billion of spending out of one Excel file. It has about 6,000 applications, roughly one for every 16 staff. Monthly reports take 12 to 15 days. The agency was created to cut costs and went over budget.
