An engineer focuses on the what, where, and how...a leader focuses on the who and why. For example you are considering adding a feature to your app. As an engineer you think of what you need to build how to implement it, where to store the data or put the logic. A manager focuses on why you should or shouldn't build it, who on the team does what part, how much it costs, etc. Imagine the transition from line cook to executive chef...when you're in charge you have to think big picture about menus and marketing and let your team handle the tasks of chopping of vegetables and plating entrees.
