Can you share your experience working on tough problems that require breadth skill set?
Once you get specific enough about the problem you’re facing, the questions and their answers are no longer constrained to a single domain.
Yet another, perhaps closer to what you mean: If you get so focused on improving one thing, you’re going to improve all the things involved, which is always a lot.
If you want to make the best widget that you possibly can, you’ll need to know about widgets, and widget making, and widget usage, and the specific application of widgets at hand, and the people who will be using the widgets, and the roadblocks that your users will face when using widgets, and the strategies for overcoming those and the roadblocks you will face when making widgets. You’ll also want to know about the people in your supervision who make widgets, and how to lead widget making teams, and how to position your team and sell your efforts to the widget company sponsoring your widget project. This requires experience with widget-project-selling design and communication. And being good at design and communication means being a well rounded human being with the capacity to grow and introspect.
And that’s just for widgets!
The above is basically a description of a project I did, but made completely generic.
