“Jim Shore and Shane Warden expertly explain the practices and benefits of Extreme Programming. They offer advice from their real-world experiences in leading teams.
They answer questions about the practices and show contraindications—ways that a practice may be misapplied. They offer alternatives you can try if there are impediments to applying a practice, such as the lack of an on-site customer.
“The explanations do not stop with just the practices. Discussion of people-related issues, such as strategies for creating trust and team cohesiveness, rounds out the book.”
