Whenever a finance IT job spec says “communication skill” or “communicator”, it could mean several things
– can understand business users
– can understand requirements
– can write (non-trivial) email
– can write reports
– can present
But I feel the most important criteria is — articulation.
I don’t know for sure, but i feel most people can do a good enough job of understanding users or requirements, but the level of articulation varies among developers.
I guess outside US and UK, some developers have problem with English.
