Question 1
At what point in a project using a waterfall model does making a change to that project become more costly than in an agile model?
- From the very beginning.
- Before coding begins.
- Just after coding begins.
- Once testing has commenced.
Question 2
In an agile model, why does the cost-of-change curve continue to rise over time instead of leveling out?
Careful, there are several correct answers.
- The codebase for a project grows over time.
- The number of non-code artifacts grows.
- The process may not be perfectly agile.
- Agile is more like an idealized waterfall.
Question 3
