Should agile teams estimate defects?
This a one question that teams often find themselves debate and my perspectives has changed over the years on this. The short answer is … it depends on your team context and what you are trying to achieve with estimation.
Estimation is a practice that helps Agile Teams forecast the effort that is required to get a task done e.g. deliver a feature and as such, it contributes to capacity planning for the team.
The process of ideating and developing products (including software products) falls within the domain of Complex Systems. A complex system is a dynamic network of interactions, where the behaviour of the system as a whole may not be predictable based on the behaviour of its component. A model such as the Cynefin Framework which was developed by David Snowden has helped with our understanding of complexity and our approach to addressing complex real world problems.
