When it comes to the whole "supply chain blockchain" thing, I agree it is easy to just think "so, you just mean a signed log?", but there is actually an aspect to the whole thing that makes actual blockchains relevant here - and that's because they're both trying to solve the "double spending" problem.
In this case the thing that a middleman might be trying to "double spend" is a part with a legitimate provenance. A simple record system might show that a middleman received part A from a legitimate source, but not immediately highlight that they sold on parts B and C too, each claiming to be part A. Blockchains solve that problem in a nice way with decentralized trust.
Now, to what extent decentralized trust is relevant in a system apparently operated by Honeywell in a way that seems completely centralized... you know as much as me.
