I also found an older post describing how they use Scrum to design the hardware to be pretty interesting: <a href="https:&#x2F;&#x2F;www.backblaze.com&#x2F;blog&#x2F;designing-the-next-storage-pod" rel="nofollow">https:&#x2F;&#x2F;www.backblaze.com&#x2F;blog&#x2F;designing-the-next-storage-po...</a>.<p>I wonder what limitations the 6-month production run requirement put on design - it would seem  you would have to be a lot more conservative in your &quot;definition of done&quot; (a bad decision can be expensive when you buy a half-year worht of gear).
