And in the Garbage In Garbage Out department:
We can talk about tracking and big data and all those things, but at the end of the day the challenges are still accuracy, relevance, and – YES – privacy.
The data must be correct.
The data must serve an actual purpose
The data must be usable – that is, with the permission and concurrence of the owner.
Otherwise the data collection and storage system is broken.
