Pro Tips for Choosing Your Topic

• Check the specific style guide of the journal or organization (e.g., ASME vs. IEEE) before deciding on a voice, as conventions vary wildly across engineering disciplines.
• Use the passive voice when the action is more important than the actor, such as describing a chemical reaction or a physical law in a laboratory setting.
• Switch to the active voice in your 'Conclusion' or 'Recommendations' to show leadership and provide clear, actionable advice to stakeholders.
• Avoid 'smothered verbs' in the passive voice (e.g., use 'measured' instead of 'measurements were taken') to keep your technical writing concise and professional.
• When writing safety manuals, always prefer the active voice for instructions to ensure there is no doubt about who is responsible for a task.
