7 Questions Engineers Should Ask Before Production

Before sending a design into production, a few critical questions can prevent a lot of problems later. While these questions may sound simple, they dictate your final cost, lead time, quality, and scalability.

This is why DFM (Design for Manufacturing) should never be treated as something that happens only after a quote. A short engineering review early in the project can identify unnecessary complexity, unrealistic requirements, or process limitations before they turn into expensive production roadblocks.

The 7-Question Engineering Checklist

Before greenlighting your next build, make sure you can answer these seven questions:

1. Is the material suitable? Ensure the chosen material meets mechanical requirements without driving up material or machining costs.

2. Are tolerances realistic? Avoid unnecessarily tight tolerances that spike machining time and costs.

3. Is the manufacturing process correct? Choose the most efficient process (e.g., CNC machining, casting, or sheet metal) for your geometry.

4. Can the design be simplified? Reduce unnecessary features to streamline production and cut costs.

5. Are standard tools available? Design with standard tooling in mind to avoid expensive custom tool fabrication.

6. Is assembly efficient? Minimize part counts and streamline component fits to reduce assembly time and error rates.

7. Can the design scale into production? Ensure the part transitions seamlessly from prototype to high-volume manufacturing.
