Inclusion analysis is the name given by Operis to a black box testing technique that it has found to make the checking of key financial ratios calculated by spreadsheet models quicker, easier and more likely to find omission errors than code inspection. 1 CALCULATE MORE THAN ONCE One approach among many [Pryor, 2004] [Panko, 2006] for improving the chance(More)
