Phone calls/voice mails
Reports
Meetings
What is the “secret” to good
team communication ?
Communicate to all the stakeholders:
1) often
2) thoroughly and
3) clearly.

Let’s look at some sample engineering-related communications:
Production / Working drawings
• Detail drawing
• Assembly Drawing
• Bill of Materials (sometimes on Assembly)
• Layout (sketch)

Graphic Communications – Illustrations
• Charts - portray relationship(s) among numerical data, for example sales versus time.
e.g. bar charts, X versus Y, stress vs strain
• Diagrams - explain how something works or the relationship between the parts.
e.g. free body diagrams to analyze static forces and moments.
• Schematics - uses abstract symbols e.g. piping schematic, or electronics schematic. • Figures - illustrates textual material e.g. design process figure • Sketches - hand-drawn preliminary, or rough “drawings”, drawn
without the use of drawing instruments.

Written Design Communications
Test Reports
• Technical reports detailing engineering / scientific tests
(on materials, prototypes and or products).
• Can vary in length from few pages to hundreds of pages.
• Contents include sections on: test objectives, test procedures,
data/results, summary and recommendations.
Research reports
• Similar to test reports
• But longer in length and broader in coverage
• Include additional sections such as: an abstract, background,
literature review, laboratory/test program description and
bibliography.

Owner manuals
• Include sections on:
Setting-up / installing the product
Operating the product
Maintaining (i.e. clean, lubricate and adjust)
Repair, if necessary.
• Can vary in length from 1 page to hundreds of pages
