Which of the following are among the documented reasons that adding features during maintenance tends to be more expensive than during initial development? Select all that apply.

As programs age, their structure tends to degrade, making them harder to understand and change

Maintenance teams are always given more budget than development teams

Maintenance work is often considered unpopular and assigned to less experienced staff

Maintenance work always takes exactly the same time regardless of system age

A new team has to spend time understanding the program before they can implement changes

Separating maintenance from development removes the incentive to write maintainable software

Lack of Incentive for Maintainable Code

Why might a development team have little incentive to write maintainable software when maintenance is handled by a different company?

Because maintainable code is always illegal to write under software licensing law

Because the development team gets no direct benefit from investing extra effort to make software easier to maintain, since they will not be responsible for maintaining it

Because maintenance contracts always specify that code must be deliberately hard to maintain

Because writing maintainable code always takes the exact same amount of time as writing unmaintainable code

Two Reasons Businesses Resist Investing in Maintainability

1 pts

volume_mute

Which of the following are reasons given for why businesses are often reluctant to spend more on development to reduce future maintenance costs? Select all that apply.

Developers are usually not responsible for maintaining the systems they build, so they see no personal benefit from extra effort

Most businesses have unlimited budgets and therefore choose not to think about long-term costs at all

Managers are incentivized around quarterly or annual spending plans, so short-term cost increases are visible but long-term gains are unmeasurable at the same time

Long-term maintainability savings are always larger than short-term development cost increases and easy to measure precisely
