Notes
- There are too few good, generalizable studies in Software Engineering.
- May need studies to provide "tiers" of observations:
- Context/ audience-specific observations
- General, regorous observations
- Test Driven Development:
- Makes no difference when measuring the internal quality metrics such as complexity.
- Makes small improvements to external quality.
- Has a high learning curve.
- Code coverage is very weakly related to quality.
- Code churn is highly related to defects.
