Chapter 20. Tailoring the Approach

In the preceding parts of this book, we demonstrated how you can systematically capture and model concerns with use cases and, with aspect orientation techniques, preserve the separation of use cases all the way to code and test. How far you apply our approach in a project depends on a number of factors. Every project is different, and you must tailor your approach. Frequently, you will apply aspect orientation in conjunction with several other techniques. The key idea is to find the right balance and steer the project to success. In this chapter, we enumerate different project scenarios and prescribe a roadmap for you to find that balance for these scenarios.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
