Documenting Software Architecture

Documenting Software Architecture When we need to explain to someone else (new developer, product owner, investor, …) how the application works, we need documentation. But what documentation options do we have that can express the whole application build

This post is part of The Software Architecture Chronicles, a series of posts about Software Architecture. In them, I write about what I’ve learned on Software Architecture, how I think of it, and how I use that knowledge. The contents of this post might make more sense if you read the previous posts in this series.

Reflecting architecture and domain in code In my previous posts of The Software Architecture Chronicles I've talked about many interesting ideas. However, how do we actually put it to practice in our codebase?!

16. No silver bullet

This chapter is a transcript of a paper Brooks wrote back in 1986 titled "No Silver Bullet - Essence and Accident in Software Engineering". In it, Brooks addresses the essential tasks of building software.

This post is part of a series of posts with my personal notes about the chapters in the book “The mythical man-month” by Frederick P. Brooks.

This chapter was added to the 20-year anniversary edition of 1995 and is a…

15. The other face

Documentation is needed. Others need to understand what our application is, what it does how it does it, how it behaves. Then the question is: What and how to document?

13. The whole and the parts

The challenge is not simply to build something that "works". It must work in the way the end user needs it, with conceptual consistency, minimal technical bugs, and that can be maintained and extended throughout a long life.
