Tech debt
Like most failed digital transformations, which is most of them, simply giving operational business teams a load of money to improve/optimise their own existing process with a new tech, just sinks money into tech debt and business complexity.
Nestle doesnt grow by giving the box packers, mould stampers, and quality control counters a load of money to improve their production line station. It designs new products which open up new markets of customers, or it designs a transformational new end to end manufacturing process which enables it to create and deliver faster and more efficiently.
The key word here is Design! And it's something that most businesses are very lacking in, at least inwards facing, even if they are imvesting in some UX for customer experience. Getting Sales, finance, HR teams to come up with AI solutions is just a waste of money.
