Questions:

1. What is the difference between top-down and bottom-up estimating? What are the advantages and disadvantages of each?

2. What is meant by “experience-based” estimating techniques? Give a brief description of each of the experience-based techniques described in the article. What are the advantages and disadvantages of each?

3. How do learning-oriented techniques differ from experience-oriented techniques? Give a brief description of each of the learning-oriented techniques described in the article. What are the advantages and disadvantages of each?

4. What do the following acronyms refer to: COCOMO, MMOE, TODSI, SLOC, SLIM, FC?

5. Briefly describe the algorithmic methods described by the author. How does COCOMO 2.0 differ from COCOMO?

6. What are function points? How is function count derived? What methods of function point analysis-based estimating are described by the author?

7. Briefly describe the emerging techniques outlined in the article.

8. How do the author’s final comments in the Conclusion section relate to the issue of identifying schedule-related risk?
