Good Software Engineers are Business Analysts Too

Good software engineers have to understand the business they're working in.

If they don't, they're at the mercy of business analysts and project managers to explain what to do.

Some of my most successful moments in my career have been when I've taken on a role of business analyst and gone directly to the source for information on what needs to be built for the business.

In other words:

You gotta write code, and be this person too.
