Technical Communication—IFiFigures

• Drawings display designs• Flowcharts display sequences of events• Tables display data

G h h i• Graphs show comparisons• Matrices display decision criteria

S ifi ti Sh t di l l ti it i• Specification Sheets display evaluation criteria

Reports present accomplishments

Accomplishments are tangible:

• A device (shown in a drawing)

• A plan for solving a problemA plan for solving a problem(shown in flowcharts and tables)
