Software Architecture: What is it and why should we care about it?

Software Architecture Overview

Software Architecture is a key component in developing a long term, successful embedded system device. However, the topic of what is included in software architecture is complex. Let’s take a look at an example of what software architecture is with an excerpt from Luke Hohmann in Beyond Software Architecture: Creating and Sustaining Winning Solutions:

“Software architecture is the sum of the nontrivial modules, processes, and data of the system, their structure and exact relationships to each other, how they can be and are expected to be extended and modified, and on which technologies they depend, from which one can deduce the exact capabilities and flexibilities of the system and from which one can form a plan for the implementation or modification of the system.”

According to Wikipedia, Agile software development is “a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams.” While there can be some variability among Agile organizations, there are a few important definitions which generally hold true. A Potentially Shippable Increment (PSI) is a 2 month period of time in which the team will commit to delivering a set of features to a customer.
