#202: Estimation - Quantitative approaches

This episode is part of a wider mini-series looking at Estimation in Software Development.

In the last couple of episodes, I've looked at a number of methods that fall under the Qualitative approach to software estimation.

Qualitative estimation is predominantly based on expert judgment, some think based on subjective thought process.

In this week's episode, I want to move on to discuss some Quantitative estimation approaches.

While Qualitative estimation is predominantly based on expert judgement, Quantitative is based on something we can count or calculate, a use of statistical analysis based on historical data.

In this episode, I specifically want to discuss two quantitative techniques - Monte Carlo simulations and Statistical PERT (or SPERT for short).
