Yes - most roll-outs will do phase approaches (unclear if Lidl did this or not). A good strategy is to do a smaller country roll-out for example, learn all of the lessons and then roll it out elsewhere. It's however not a blanket strategy and requires context to decide which is the right way.

Lidl rolled it out in the smaller countries, learned the lesson that it's not going to work, and stopped it.

What I find crazy is that it still took 500M to figure that out.

It took that much for all levels of management involved to admit it was hopeless and for the top level to ax them.
