In this presentation I explained the difference between UX and UI and told about a UX strategy we created. I explained how a UX strategy can help build a business case to address the UX and what tools you can use to support this process. Tools discussed were the SAP Workload Monitor and the Keystroke-Level Model, used to measure user productivity.
