Not only have you given a great explanation of what wireframes are, but you have clearly explained why they are so important – to all team members and the client.

It is not just another step in the development process, it is a solution to unnecessary rework at the end of a project. Clear requirements and team collaboration result in a better product with a better user experience.

Thanks for the share!

I think you might love the ease of use my little tool http://www.Simulify.com/ provides in make & sharing interactive wireframes. You can annotate and gather feedback online.

It can be a real help for software development company like yours.
