When looking over a list of feedback, it's hard to resist focusing your attention on the people who're shouting the loudest. But, if you become overly reactive to this type of feedback, you'll never have time to work on longer-term initiatives. Sometimes people refer to this as the trade-off between focusing on problems that are urgent versus problems that are important.
If a suggestion is neither urgent nor important in isolation, it's likely to be left at the bottom of the priority list, meaning that it'll be put off until later. The unfortunate consequence of this is that as a suggestion starts to feel ignored, people are less likely to offer the same suggestion again in the future. So, unless you're aware of the historical context, it's easy to miss that there's been a consistent sentiment that's been left unaddressed.
