Engineering students spend years learning math, physics, analysis, and CAD. Very few learn how to participate in a design review. That is unfortunate, because design reviews may be one of the fastest ways to develop engineering judgment.
Design Reviews Are Not About Finding Fault
Many early-career engineers walk into their first review expecting approval. Experienced engineers walk in expecting questions. The purpose of a design review is not to prove that a design is perfect. It is to expose assumptions before they become expensive mistakes.
Good design reviews answer questions such as:
What requirements are driving this design?
What happens if a supplier changes material?
Can manufacturing actually build this?
What are the failure modes?
Have we considered assembly and serviceability?
Is there a lower-cost approach that still meets performance goals?
Finding these issues before tooling, testing, or production saves both time and money.
Design Reviews Teach Skills School Rarely Covers
Participating in reviews helps engineers develop capabilities that extend far beyond design.
Communicating with Precision
Engineers must explain decisions clearly and support recommendations with data.
Receiving Feedback Professionally
Strong engineers learn to separate themselves from their designs. Feedback is not personal. It is an opportunity to improve the product.
Understanding Tradeoffs
Every engineering decision involves balancing competing objectives.
Performance.
Cost.
Schedule.
Manufacturability.
Reliability.
Design reviews make those tradeoffs visible.
How to Get More Value From a Design Review
Before your next review, ask yourself:
What assumptions am I making?
What data supports my decision?
What questions would manufacturing ask?
What would a supplier challenge?
What would happen if I had to reduce cost by 10%?
Answering these questions before entering the room changes the discussion from defending a design to improving a product.
The HatchOne Perspective
At HatchOne and within The Engineering Exchange, we teach that engineering growth is not measured by how quickly someone can model a part. It is measured by how well they understand the system around that part.
Design reviews help engineers build that understanding faster than almost any other activity.
If engineering school teaches us how to solve equations, design reviews teach us how to make decisions.
