I am new to estimation techniques. I am trying to compare different techniques; mainly Use Case Point (UCP), Function Point (FP) and Work Breakdown Structure (WBS). In WBS context can I say:
- WBS approach is dependent of the technology being used (e.g. Java/.Net will have different estimation figure).
- It helps to roll up the effort across various tasks.
- This technique would be more reliable if there are complexity guidelines that help to arrive at the individual task effort.
- Unlike UCP/FP WBS does not help me to arrive the application size.
Are these understandings correct?
