Prerequisites:

• Mostly working prototypes
• Some testing & debugging

Tools:

• Bug-tracking software
• Environmental testing chamber
• Emitted radiation sensor

Next Step:

• Testing & Debugging (when it breaks)
• Production

Once your design is sufficiently debugged, bench tested and functional you’re ready to move on to qualification & environmental testing.

TODO

• Types of qualification
• Why qualify
• Order of operations
• How to debug qualification issues

Assuming you discovered some bugs or failures, you need to head back into testing & debugging, make some design changes and produce more prototypes.

Once you have made it through internal and external qualification testing, and your product has been certified to an acceptable level you’re ready to move on to production.
