[ Numbers and words ]
Communicating engineering outputs means being able to communicate with numbers and words. In the process of adding value to the information we receive, and passing it on for the next step of the process, there will always be either numbers or words involved.
Numbers could mean graphs, calculations, charts, infographics, or tables. Words would usually be the explanation and interpretation, often of the output from numbers.
Numbers are finite, organised, logical, and either true or false. Words are ambiguous, wandering, descriptive, and can suffer from run-on-and-on. One is not better than the other, and engineering outputs absolutely require understanding both.
