Agile Technical Practices Distilled

By: Pedro M. Santos, Marco Consolaro, Alessandro Di Gioia

Overview of this book

The number of popular technical practices has grown exponentially in the last few years. Learning the common fundamental software development practices can help you become a better programmer. This book uses the term Agile as a wide umbrella and covers Agile principles and practices, as well as most methodologies associated with it. You’ll begin by discovering how driver-navigator, chess clock, and other techniques used in the pair programming approach introduce discipline while writing code. You’ll then learn to safely change the design of your code using refactoring. While learning these techniques, you’ll also explore various best practices to write efficient tests. The concluding chapters of the book delve deep into the SOLID principles - the five design principles that you can use to make your software more understandable, flexible and maintainable. By the end of the book, you will have discovered new ideas for improving your software design skills, the relationship within your team, and the way your business works.

Bounded Contexts and Communication

If you remember the Alan Kay's quote in the previous lesson, the most important thing in making a great, growable system is designing how its modules communicate. The enabling factor here is modularity. Kay takes for granted that the system is fractally composed of modules, and says that how they communicate is the key point.


The key in making great and growable systems is much more to design how its modules communicate rather than what their internal properties and behaviors should be.

From this point of view, since bounded contexts are high-level modules, there should also be a special focus on communication between them. Furthermore, given that to reach a good understanding, we should move the focal point to the external system (as noted previously by Russell Ackoff), this explains why it is important to understand the value stream in order to design the best interaction flow between the bounded contexts.

This logical, high...
