    And where are we headed?

    Always forwards!

    New mobile OSes come and go every year.

    The Desktop and Mobile is seemingly merging

    Industrial applications look like app store games

    Continue to drive the state of the art UI development

    Every screen wants to have the same content and UX as a mobile

    No one screen size or platform suffers

    Better Life Cycle Management

    Historically, shipping a Qt application has been a complicated task

    Goals 1. Simplify dependencies and packaging steps for Qt 5 applications (Framework tasks) 2. Provide wizard / automation tools to further improve workflow (Tooling tasks)

    Distribution Channel Independent

    As one potential distribution method the Qt Installer Framework will be integrated into Qt Creator

    Develop Package Distribute Design
