Veering slightly OT here, but still on the theme of business models, consultants, and expensive "advice" from "experts", it's fascinating how many allegedly intelligent people can't read the runes.
My specialism is IT. I "divined" (i.e. saw the bleeding obvious) back in 2010, that the PC market (desktops) was dead. There was no room for innovation in hardware, as niche platforms (gaming, tablets) were becoming cheaper and better. In addition the rise of the ismartPhone was filling gaps where people didn't have desktops.
The result is the market is mature. Sales of desktops are now driven almost exclusively by the replacements, and "My first PC" markets. Dramatically smaller than (say) 2000-2010.
And yet I have read report after report predicting an upturn in sales "next year" for ages.
The whole world has changed. The moving finger has writ.
Here's a prediction for the next 10 years: Big stores (e.g. Tescos) will leverage their real estate, and expand the concessions side of their operation. A trip to Tescos will not only allow you to do your weekly shop, but visit more niche outlets (Timpsons is just the start). The inside of the store will start to look more like a covered market, with lots of small - maybe (and hopefully) local businesses. Homebrew, haberdashery, niche tech - all the shops lost to the high street. If the big players do it right, and offer their backoffice systems to the small independents, we could see online deliveries by Tesco for their partner stores. Add to the the potential for Tesco to offer Amazon lockers, and it's a bright future for those that can get it right.
That's the future stores like BHS should have contemplated. But sometimes the more you pay people, the less they risk.
The latest source of amusement to me is the decline in iPhone sales ... mature market again.
