The following checklist will serve as a helpful guide in reviewing a design:

1. Keep the number of seperate pieces in a subassembly as low as practicable by  combining single components into one assembly if functional requirements permit.

2. Remember to keep anthropometrics (standard body measurements) in mind.

3. Check particualrly left- and right-hand parts to determine whether they can be made identical and so avoid stocking an extra part.

3. Check advisability of using lock washers assembled to bolts as purchased assemblies.

5. Check to determine whether similar parts between models can be standardised.

6. Keep the targeted customers wants and needs in mind as they're the ones who will use the end product.

7. If subassemblies require alignment, design the parts to secure such alignment without the use of special jigs by providing tabs, shoulders, notches, or contour locators.

8. Provide adequate clearances between parts for assembly tools.

9. Specify the simplest, most effective, and cheapest type of attachment practicable and commensurate with the functional requirements.

10. Avoid blind-riveting operations wherever possible.

11. Remember that your assignment protfolios purpose is to communicate the design to the examiner. Flashy images that don't show off the design specifics are useless.

12. When rivets are used, provide sufficient clearnances between parts and from flanges to permit the use of a standard riveting gun.

13. Avoid the use of slotted nuts and cotter pins wherever possible.

14. Standardise bolt and thread sizes as far as practicable. Hold the number of bolt lengths to a minimum and recheck frequently to reduce number of lengths in use.

15. Don't be afraid to take inspiration from existing products. After all, "There is nothing new under the sun". All designs are inspired by another source.
