I had to laugh when I read this. It is just an uninformed position to take these days. Yes, I get it that IT infrastructure may change a bit faster than your other asset classes, but they share far more that you have bothered to see in reality.
For example:
And that was just a simple item. I think what you have failed to consider is that almost everything is now part of the IoT universe and many catagories that you thought to be ridiculously “slow moving” items are actually probably doing more than Cisco in the field of advanced communications and internet connectivity.
There are HVAC companies now that are installing large tower/building class air conditiojning systems that are controlled by embedded linux systems and wifi connect to each other on the same building through a proprietary router that has it’s own satellite link to the internet. These systems monitor themselves for service related issues and can call for their own PM’s without ever involving a human being. They also get constant anf frequent firmware updates through the link to keep their systems running. Ultimately some IT guy in some office in some part of the world has to maintain that software and all of those embedded linux controllers. It is no longer just a dumb air conditioner and the people that service this stuff now also need to have not only good computer foundational knowledge but also network debugging abilities and telecommunications backgrounds.
John Deere, Kubota, etc. agriculture equipment suppliers have automated almost everything in these pieces of equipment and even linked them together with CDMA or GMS cellular data links so they can coordinate with each other, with the local weather service, with the local EPA, and other entities in order to solve problems and keep production moving. Everyone of them requires a network specialist to also be able to understand the heavy equipment mechanics of their system.
I am sorry, but I believe that you have just been looking at your computer screen for way too long to understand that the world has changed around you and service providers as well as asset managers are begging for typical IT related items to be included in the standard software for asset management and service contract implementations.
Even basic home air conditioners are now looking for a wifi connection so they can report their own issues to their owners and even make the call to schedule their own repairs. My local HVAC vendor recently offered to replace my main unit with one that had a cellular connection built in with a lithium standby battery so it could call for automated instructions on what to do after a natural disaster! He said it would even receive disaster alerts and automatically go into a hibernation state so it would be easier to recover from if all was well later. Of course that also meant it needed a quarterly firmware update.
Please… don’t try to separate asset management from IT management. Find a way to make them work together in the same application. Yeah, maybe the guy renting tables and chairs to wedding receptions will not need all of the features but, we are rapidly approaching a time when even that may change.
So, by the time you actually get an application ready to deploy, I don’t want you to have spent all your time making something that may already be outdated and pigeon holed into a corner that you would have to develop your way out of again and in short order.
Just an opinion, and you know what they say about opinions
