Actually estimation can be done with different techniques
and one of the technique would be WBS(Work breakdown
structure).
In this technique, we would
1. break down the funcitonalities into lower level
2. Identify the number of scenarios for each function
3. Prioritize them based on the complexity
4. Assign the time taken taken for High, Medium, Low
complex scenarios
5. Effort Estimates = Multiply the time taken with the
number of identified scenarios + 30% contigency
This is the answer I gave at the interview but the
interviewer was not satisfied and he was questioning
"What is the factor that you take into consideration for
estimating the time taken for the prioritized scenarios?"
Can anyone of you help me out with an answer?
