@Ricsca, imagine you develop and sell a unique product. You have already thousands of customers, 80% are happy. 20% are not. They say:
Your green is not green enough, please make it greener.
Move this holder to the other side, it does not make sense to have it here
Integrate a GPS chip so that if lose it, I can find it easily (after all, even Apple does so!)
Make it a bit smaller so that it fits in my Gucci woman's bag, there are only some millimeters too big
Disappointed, that this is not waterproof
No app? Well, how am I supposed to use it without an app? We are not in the Stone Age.
And so on.
On the other side, you have your own roadmap and ideas on how the product should be developed further. And you have some bulk customers, saying, if you put this glittering thing over there, I will buy even more.
If you care about your business, you would hear suggestions and evaluate if the green should become even greener. Is it something that will help to boost your sale? You will keep your roadmap and work on new ideas and features instead of following ALL suggestions your customers ever made, sane or not. And you will try to satisfy your key customers, sane or not, to keep them buying even more of your products.
You must discard some suggestions, that require significant effort and promise only a small outcome. The customer whose suggestion you've discarded will say: "you are simply not interested in improving your product". And that will not be true. You know it.
