Building software is a lot like creating music as an ensemble. In an orchestra, each person has their part in the section, and each instrumental section is significant in bringing a work like a symphony to life. As testers, we are uniquely situated to have visibility into the strengths, weaknesses, and opportunities of our system, as well as understanding how our part fits in with the whole. When we care deeply about our work and how it depends on and supports others, we create a result we can be proud of.
Learn from personal experiences in both software and music how you can bring order to chaos, visibility to opaqueness, and simplicity to complexity. See the system! Making music from notes on a page is not magic, nor is making a software system function well. Although music analogies will be interspersed, no live music will be performed.
