Product, Management, or just bad luck?

After the most recent quarterly which showed a drop in YOY sales, wondering what people's thoughts are. Is this product just not viable in today's world? OR Has management got the execution all wrong? OR Neither of the above, has it been just a series of unfortunate events that has delayed performance. OR Nothing unusual about where the company is at, at this stage of their story. These lulls happen. SP is just reflective of an impatient market. Or perhaps it's a combination of these or something completely different.
