As humans, we need to be convinced of the value of the work we are undertaking in order to put our mind and soul into it, to believe in its efficacy so that we can conjure up a passionate endeavor to make it successful.
In this chapter I shared my rationale for and belief in the value of a well-defined software architecture in relation to developing a successful software system. I defined a software architecture (that is, the What) while also emphasizing its value (that is, the Why).
The chapter also introduced the notion of architecture views and viewpoints and provided an overview of one viewpoint library that I tend to follow quite often.
The next chapter highlights the various facets of software architecture that are described in the rest of the book. The fun begins!
