and Communication
A Communication Example
Two missile electrical boxes manufactured by different
contractors were joined together by a pair of wires.

A Communication Example (continued)
Thanks to a particular thorough preflight check, it was discovered
that the wires had been reversed."

After the Crash...
...
The post-flight analysis revealed that the contractors had indeed
corrected the reversed wires as instructed.

Communication is important
You will spend more time communicating than modeling and
coding
A software engineer needs to learn the so-called soft skills:
technical writing, reading documentation, communication,
collaboration, management, presentations.
It’d be nice for each of you to (acquire and) demonstrate the
following skills:
 Management: Run a team meeting
 Presentation: Present a major aspect of your project
 Collaboration: Negotiate requirements with the client and with
members from your team
 Technical writing: Write part of the documentation
