It's easier to write code when you understand the context. The customer requirements aren't always flawless and might make assumptions about things that you don't know.

During my career I've had to study:

  - electrical engineering (phase angles, current transformers etc)
  - finance (payroll and accounting)
  - building management (maintenance schedules etc)
  - mining (terminology, how explosives are set in underground and open mines)

I'm not an expert on any of those, but I know enough to be productive and know _why_ I'm doing the task I'm assigned.
