Hardware Validation Heirarchy

Overview of testing milestones for developing complex hardware. This would be for something with many PCBA, modules or devices that integrate into a larger system and several to many team members. Validating systems does not always require this many steps. It can be time consuming. But if hardware is rare (in quantity) or is very expensive it might be worth injecting caution into the project.

Immune System Notes

  1. implementation: innate vs adaptive
    a.) mediated (cell) vs non-mediated (humoral)
    b.) cell mediated (eg phagocytosis, interferons) vs system mediated (fever, skin, hair, mucus, acid/base, complement); inflammation is kind of both
  2. material: alive vs not alive
  3. location: surface vs internal
    a.) internal: intra-cell vs inter-cell
    b.) surface: skin vs everything else
  4. type: direct (attack) vs indirect (interference)
