Explain why this estimate should be adjusted to take project, personnel, product, and
organizational factors into account. Suggest four factors that might have significant effects
on the initial COCOMO estimate and propose possible values for these factors. Justify why
you have included each factor.
23.9. Some very large software projects involve writing millions of lines of code. Explain why the
effort estimation models, such as COCOMO, might not work well when applied to very large
systems.
23.10. Is it ethical for a company to quote a low price for a software contract knowing that the
requirements are ambiguous and that they can charge a high price for subsequent changes
requested by the customer?
