I would assume this is more about talking like a manager. Engineers are leaders too. Technical leaders. Talking like a manager primarily means to focus on time and money. How much does it cost/save/earn? How long will it take? Just two numbers. At least managers would like it to be that simple. It isn't and that makes the translation between management and engineering hard. You still must try to answer the questions though. Pick a random open bug or feature: How long will it take? How much value does it bring to the company? If you can answer both questions precisely in a sentence you should be fine. You probably cannot. Now try harder. What has to change so you can? Just get some info from someone? Change fundamental processes in your company? Now you have work to do. Before you start doing that, ask again: What is the value in dollars? How long will it take? Oh, and put a limit on the recursion there.
