I can understand that it takes a long time to create new stock control systems/interfaces. What I can't understand is why they're not shipping stock from the warehouses to the stores. Even if they can't be "accurate" as to what each store actually needs, surely it's better just to get stock out there so customers can actually buy it, rather than being in darkened warehouses unable to be sold because their ordering system is still down?
Same with the Co-Op. 4 weeks now. Our village store is virtually empty. No point going in any more. Sometimes they have milk, sometimes not, same with bread, sandwiches, soft drinks, crisps, chocolate bars. I carried on going in daily for my lunchtime "meal deal" and accepted the lack of choice for the first 2/3 weeks, but this week I've given up and go elsewhere - I literally couldn't make up a meal deal anymore. No crisps at all, no soft drinks at all, and a very poor range of sandwiches. There'll be warehouses somewhere full of tinned and packet goods, crisps, chocolate bars etc - why can't they just send a random few cages of things to the shops so that they at least have something to sell?
One of my clients has 2 convenience stores - there are 3 villages in a kind of triangle, he has stores in 2 and there's a co op in the other. His sales in his stores have doubled and trebled over the past few weeks and are still growing. The Co Op must be losing tens of millions in sales/profits. My client isn't complaining! But at the same time, on the top of his "to do" list is to change his franchise for one of his stores - he's currently using the same franchise/supplier for both, and now realises that if his franchise supplier is similarly hacked/attacked it would probably bankrupt him, so as soon as possible, he's moving one of his stores, so that if the worst did happen, he'd still have another store running normally - he could just about financially cope with one shop severely disrupted but couldn't survive if it happened to both!
Something has gone badly wrong with both the Co Op and M&S. It's not just the hacking in the first place, it's the complete absence of any "Plan B" for when the stock ordering/delivery system fails. Fair enough for a short delay until either the main system is sorted or an alternative system can be used (even if manual), but when it becomes week after week of stock not getting to the shops, it's a secondary failure of resilience planning.
