As we go by the analysis in policy-based design, it is a delicate task to create a good set of policies, just the right number.

He is particularly known for his pioneering work on policy-based design implemented via template metaprogramming.

Several phrases from the book are now used within the C++ community as generic terms: modern C++ (as opposed to C/C++ style), policy-based design and typelist.

Policy-based design, also known as policy-based class design or policy-based programming, is a computer programming paradigm based on an idiom for C++ known as policies.

While assembling software components out of interchangeable modules, communicating with each other through generic interfaces, is far from a new concept, policy-based design represents an innovation in the way it applies that concept at the (relatively low) level of defining the behavior of an individual class.
