Self-Checks In Spreadsheets: A Survey Of Current Practice

A common application of spreadsheets is the development of models that deliver projections of the future financial statements of companies established to pursue ventures that are subject to project financing. A survey of 11 such spreadsheets prepared by a range of organisations shows that the amount of self-testing included in such models ranges between one formula of testing for each three formulae of calculation, down to essentially no self-testing at all.
