9789082888034 - Requirements Introduction to specifying requirements
2e hands

Artikelomschrijving

You have requirements for everything you use. A watch has to show the exact time. It must be possible to use it when diving, the wristband should not wear rapidly, et cetera. This does not only apply to things we have. This also applies to software we use. Software for making invoices must be able to deal with changes in VAT percentages that have to be applied. The software should not only be able to make an invoice that meets the legal demands, print it, et cetera, but should also, when making a credit invoice (an invoice that is meant as a reversal of a previous invoice), use the VAT percentage that was used in the original invoice, even when this percentage has changed in the meantime. When you don?t specify the correct requirements, you will get something different from what you expect. E.g. a watch that is difficult to read, software for making invoices that uses the new VAT percentage in credit invoices instead of the percentage in the original invoice.
