One way this ux tool UserVoice can be used is to quickly install a forum in your company's website to get feedback from colleagues while iterating on a Product Roadmap. Thus, everybody has buy-in while components of the Roadmap are being developed.  Your colleagues can submit and up-vote/down-vote ideas.*

From the UserVoice website:

What is UserVoice?

UserVoice is a software-as-a-service provider of customer support tools that include:

  • Feedback forums to understand the ideas users care about most.
  • A support ticket system to track and respond to customer support requests.
  • A knowledge base to answer common questions and help users find the information they need when they need it.
