SCRUMBOK

This book provides a detailed, easy-to-read account of one Swedish company's experience implementing Scrum and XP, following the team as they improved their process during the first 12 months of use. Author Henrik Kniberg details leading the team through multiple experiments in strategy and practice... This book could have been called Estimating and Planning Agile Projects. Instead, it's called Agile Estimating and Planning. The difference may appear subtle, but it's not. The title makes it clear that the estimating and planning processes must themselves be agile. Without agile estimating and planning, we cannot have agile projects.
