Balancing thinking and doing is one of the Hard Problems™ of software development. I suspect successful methodologies work because they formalize the act of thinking about the code before implementing it. And that when methodologies fail the reason could be that they can easily be implemented such that people think more about the technicalities (assigning work, deadlines, estimation accuracy etc.) than the development (modularity, overlap with existing work, conflicts with concurrent work, security, third party dependencies etc.).
