Is your business a zombie? Here’s how to tell

I’ve been frequenting a local frozen yogurt shop for a couple of years now. It’s a wonderful break, especially during the summer. But they’ve been through rocky times, with changes of ownership and rebranding.
 
Ordinarily this would make me optimistic, but in this case the company seems to have lost its way. Honestly, I’m surprised it’s still in business.
 
This isn’t about a company’s size. I know of many successful, sustainable, one-person businesses. There’s many wonderful shops around town which have been in operation for years and years, building a strong reputation.
