In this episode we look at No Estimates by Vasco Duarte. The book challenges traditional project estimation methods in software development. It critiques the reliance on estimates, highlighting their potential to cause harmful targets, internal politics, and a "death-march" mentality among teams. Instead, it advocates for a Lean and Agile approach, emphasizing value delivery, continuous improvement, and waste reduction, drawing parallels to Japanese manufacturing principles. Prioritization and flow are presented as key elements, with a focus on delivering small increments of value quickly. The importance of understanding and responding to change, rather than rigidly adhering to initial estimates, is underlined. The writing encourages focusing on value and using available data to forecast progress, promoting a more flexible and responsive development process.
