Complexity indicators: estimation precision and test types
The document discusses the complexities of product development, emphasizing the need for effective working methods to manage product intricacies. It introduces the Cynefin framework to categorize different types of complexities and suggests using indicators for estimating project complexity and precision. Additionally, it highlights approaches like Scrum and XP for adapting workflows to foster development efficiency.
