Business modelling began roughly at the time that computers began to find their way into the business and finance workplace. Apparently Deutsche Bank in London had computers in 1987 and actually used them to provide numerical financial analysis.

VisiCalc was the precursor to Lotus 123 and Excel, and had much the same basic grid structure. The initial idea was to provide an extremely flexible grid system rather than attempt to better answer specific questions such as company financial analysis.

Initially the spreadsheet was used to sense check what a person had already calculated using other methods. Compare this to now where the spreadsheet is at the heart of all company finance and any transactions. The complexity of spreadsheets has grown also, largely driven by the technical advances in computing.

Excel has become the leading spreadsheet software in the world. Excel is used to model financial, economic, scientific or other data. However, Excel is also the software of choice for presenting data that may be calculated in other more complex software.
