QuantX Ops Versus Spreadsheets: An Honest Comparison

Vendors are rude about spreadsheets. They should not be: Excel is the most successful business software ever written, and for a great many jobs it remains the right answer.

Where spreadsheets genuinely win

• One person, one analysis, once. Nothing is faster.
• Shape you have not decided yet. A model you are still arguing about should not be a database schema.
• Arithmetic nobody else depends on. A quick cash-flow projection is a spreadsheet, and always will be.

Where they stop

The break comes at a predictable point: when more than one person needs the same number at the same time. After that, every property that made spreadsheets good turns against you.

The problem	In a spreadsheet	In QuantX Ops
Which copy is current?	Whichever was emailed last	There is one
Who changed this figure?	Unknowable	Recorded, with when and why
Who may see salaries?	Anyone with the file	A permission
Does the invoice match the order?	Checked by hand, sometimes	Arithmetic, every time
Is the ledger current?	After somebody types it up	Written by the documents
What did we quote in March?	If the file survived	The document is still there
Approval	An email saying "ok"	A routed, recorded decision

The cost is real but invisible

Nobody bills for the hour spent reconciling two versions of the same figure, which is why it never appears in a business case. Construction is among the least digitised sectors on McKinsey's index — and the productivity gap that goes with it is about 1 percent annual growth against 3.6 percent in manufacturing.

The honest recommendation

If you are under about fifteen people and one person does the numbers, stay on spreadsheets. Past that, the question is not whether to move but how much rework you will do first.

Next: what it costs.
