I like to use the XYZ metric. (aka: eXamine Your Zipper)
1. Does the zipper on the fly of
your pants need to be automated?
2. Does the zipper on the fly of
your pants ever need costly repairs?
3. Does the zipper on the fly of
your pants need regular maintenance?
4. Does the zipper on the fly of
your pants expend disposable accessories?
5. Does the zipper on the fly of
your pants need to be context aware?
6. Does the zipper on the fly of
your pants require internet connectivity?
7. Should the zipper on the fly of
your pants be controllable via cell phone app?
8. Should the zipper on the fly of
your pants monetize potential advertising space?
9. Should the zipper on the fly of
your pants collect behavioral analytics?
10. Should the zipper on the fly of
your pants enforce DRM policies?
A sort of 10 commandments of IoT, if you will. Shockingly, some people will answer an emphatic YES to all questions.
