Mythbusting Software Estimation
Estimating software projects has proven to be particularly challenging. Over-running schedules happens frequently in our industry. As a result software estimation is often viewed as a black art. In this session Todd will look into some of the reasons for these challenges by exploring a number of myths of software estimation and then setting out to validate or bust these myths.
Some of the myths that will be explored include:
- Historical Estimation Accuracy
- Relative Estimation
- The Cone of Uncertainty
- Scope Creep
- Estimation Tools
- Wisdom of Crowds
Outline/structure of the Session
This talk is a minor update of the presentation I gave at Agile India 2014.
I start by having everyone estimate the number of jelly beans in a jar. I come back to this later.
I then do a bit of test first by having the audience predict whether a 10 myths about software estimation are true or not.
I then go through each of the 10 myths and present research results to validate or disprove the myth.
Learn some of the misinformation about estimation that has permeated our world. Also learn a bit about what you can do about it.
