Ryan Ripley “highly recommends” Predicting the Unpredictable: Pragmatic Approaches to Estimating Cost or Schedule. See his post: Pragmatic Agile Estimation: Predicting the Unpredictable.
He says this:
This is a practical book about the work of creating software and providing estimates when needed. Her estimation troubleshooting guide highlights many of the hidden issues with estimating such as: multitasking, student syndrome, using the wrong units to estimate, and trying to estimates things that are too big. — Ryan Ripley
