1. The typical software development project takes 12 to 23 months.
2. To be considered a large system, a system today must contain at least 50,000 lines of executable code.
3. What percent of the $92 billion software market is commercial "shrink-wrap" personal computer products? less than 10%.
4. For a medium-sized software system, how
many lines of executable source code are
typically produced per day per person (averaged over the entire
period of
development). Less than 10.
5. The approximate number of errors found in every 1000 lines of executable source code during development of a software system is 50 to 60.
6. Approximately what percentage of software system that begin development are finally completed? 70 to 79%.
7. Most errors found by users in software are the result ofb. difficulties understanding the problem statement.
8. The cost of owning and maintaining software is typically 2 times as expensive as developing the software.
9. A 1979 study by the Government Accounting Office found that for software development contracts:
2 ___ % were used as delivered.
3 ___ % were used after rework.
45 ___ % were abandoned or reworked.
20 ___ % delivered but not used.
30 ___ % paid for but not delivered.
10. A more recent study (1995) of 365 Information Systems professionals found the statistics on software development project:
16 ___ % successful.
53 ___ % operational (but less than successful).
31 ___ % cancelled.
Only 16.2% of software projects are completed on-time and
on-budget. In
larger companies,
a meager 9% of technology projects come in on-time and
on-budget. In addition, about one
third of all projects will be canceled before they ever get
completed. Further results indicate
53% of projects will cost an average of 189% of their original
estimates. In financial terms
this analysis revealed that over $100 billion in cancellations
and $60 billion in budget over
runs occur in the Software Sector annually.
