The most common reason cited for a customer ceasing to use a product or service isn’t that they have a major problem. In 70% of cases they leave due to receiving poor quality of service.
Involving users in product development isn’t just a great way to build an exceptional product that your users need, but it also makes them feel more involved. Long term that’s only good for business, both in terms of retaining more customers and increasing their average spend.
Tools like UserVoice are great for encouraging customers to contribute to customer development, just make sure you respond to requests and engage with anyone that comments.
