Clean Architecture: A Craftsman's Guide to Software Structure and Design (Robert C. Martin Series)

Notice how well those three align with the three big concerns of architecture: function, separation of components, and data management.

If you give me a program that works perfectly but is impossible to change, then it won’t work when the requirements change, and I won’t be able to make it work. Therefore the program will become useless.
• If you give me a program that does not work but is easy to change, then I can make it work, and keep it working as requirements change. Therefore the program will remain continually useful.

architecture is to minimize the human resources required to build and maintain the required system.
