Key quote:
>Unlike many of their competitors, Lidl bases its inventory management system on purchase prices. The standard SAP for Retail software uses retail prices. Lidl didn’t want to change, so the software had to be adapted.
What if the business model of Lidl is way better than the standard? Then Lidl is very wise not to follow how SAP works.
Is Lidl earning more money than their competitors because they base their inventory management system on purchase prices while others do not? Then build/buy a system that handles that and it could very well be worth it if you look at the business case
But if it is like that because that is how we started out and we cannot quantify how much better it is...then maybe you should just change your process.
Also
"Critics inside Lidl say that KPS was too slow. But Matthias Nollenberger, a senior manager at KPS who was responsible for overseeing the eLWIS project, says his company was working too short deadlines compared to other similar projects"
I belive when you have the choice between aborting 500 million and increasing some deadlines, I doubt they were the problem. It simply was not possible to adobt SAP with reasonable amount of money. And the consulting company or SAP should have said that at some point clearly.
