Working with Business Analysts, Product Owners, and Subject Matter Experts's to establish Use Cases, IA/SiteMaps, Activity Workflows and Data Sources.
Work with Developers Product Owners and Business Analyst's to show the navigation, key pages, and how the site/product is structured
Use the Workflows/Taskflows to present in (LucidCharts, JustinMind, Axure) how the page/product will function and visually show the layout. Testing these wireframes with "Users" allows me to update any workflows/prototypes before passing it off to Development and moving on to HiFi mockups.
Taking what I learn from User Testing, and Applying Branding and Standards to the Wireframes and of course... Testing it again. before passing it off to Development.
