Few words about refactoring. And elephants

I was convinced that it was trivial. Communication from and to the module is done entirely via the module’s API. So it’s enough to move all files from the obsolete module to the other one and done. Right?

But from about one and a half months I simply… don’t code at all! It’s because we have significant changes in our company. Teams started to be interdisciplinary, that means to developers joined marketing, analysis, communication guys. And I was responsible for helping people understand the change. In fact, I was true, full-time Scrum Master…
