The importance of specification
„Experience in a number of large projects has shown that
the vast bulk of the costs of a software project lies with the
fixing of errors at the implementation and test stages of the
work.“
„However, more detailed investigation reveals that avery
large percentage of these errors are traceable to imprecision
in the early stages of the project.“
„That is, the high costs during the implementation and test
phases are largely caused by false economies at the
specification and design phases.“
„This occurs because of loose wording or lack of essential
detail at the specification phase“
