“Perhaps you’ve read a book, on Extreme Programming and have decided that is the right approach for your company. Or maybe you attended a Certified ScrumMaster training course and think Scrum sounds good. Or maybe you read a book on a different agile process, and it sounds perfect for your organization.
In all likelihood, you’re wrong. None of these processes as described by their originators is perfect for your organization. Any may be a good starting point, but you will need to tailor the process to more precisely fit the unique circumstances of your organization, individuals, and industry.”
