Digital in a physical world
Sometimes, it’s not that easy, for software developers and others in IT, to understand the implications of physical things.
Physical items, need to be manufactured, sold, shipped, sometimes installed and maintained in a very different way from software only products. When you add software to physical items, the level of complexity raise very much.
You also have to manage ownership of the physical products, if you sell them or subscribe them, i.e. renting out them. Then this must be combined with software updates and licenses over the lifetime of the physical products.
This is the complexity telcos had for very very long time, and manufacturing companies need to strive for to solve.
