Similarly to Test Driven Development (TDD)--Writing tests before code--, my current team is following a Toggle Driven Development: Writing toggles before code.
The main point is: if you are using toggles, consider designing/creating/refactoring the toggle strategy before writing code.
Before getting into TDD, I got into writing tests for the code. It took me a few years until I fully understood the value of writing the test first. It seems to me that toggles are following a similar pattern. I wonder if there will be such a thing as Toggle Driven Development.
