Growth of Software from 2000 to 2010
The 2000s was an explosive decade in software growth, both among traditional
forms of software and also for computer games and dozens of new niche applica-
tions that sprang up like mushrooms after a rain.
Table 9.2 shows the approximate number of U.S. software applications created
during this decade.

At the end of this decade, a new metric called technical debt was introduced by
Ward Cunningham. Unfortunately, technical debt, cost per defect, and lines of
code are not suitable for economic analyses due to uncertain definitions that have
large variability from group to group.
Technical debt only covers about 13% of the true costs of quality, and it ignores
canceled projects that are not delivered. Lines of code ignores requirements and
design defects and also penalizes high-level languages. Cost per defect penalizes
quality and achieves the lowest results for the buggiest software.
