2. Uses data from past projects and hence is more accurate and predictable.
3. Function systems and data systems are calculated separately resulting in more accuracy.
4. Easy to use with structured methodologies.
5. Continuous improvement activities are used for the estimation techniques.
6. It is easy to use with the structured methods and with object-oriented classes, services and so on.
