Chapter Three of Head First Software Architecture covers our Two Laws of software architecture: 
1) Everything in software architecture is a trade-off
2) Understanding why is more important than understanding how

In this episode, we discuss the origin of these two laws, why we consider them universal, and the (sometimes deep) implications of them for architects making trade-off decisions.

In this episode, we cover the first of the core four dimensions that make up software architecture: architectural characteristics. We discuss what they are and answer questions about derivation, composition, and a host of other factors required to understand this building block of structural design.

Covering the first chapter of Head First Software Architecture, this episode dives into the spectrum of differences between architecture and design. We also cover the four dimensions of software architecture, which forms the narrative scaffolding for the next few chapters: architectural characteristics, architectural decisions, logical components, and architectural styles.
