+\begin{frame}{Usability Studies}
+\begin{enumerate}
+\item Usability studies conducted with:
+\begin{itemize}
+\item ‘experienced users’ who have using the app for a few weeks,
+\item ‘novice users’ from the low-numeracy target group, with no knowledge of the app
+\end{itemize}
+\item With both groups, we replicate ordinary circumstances of use and observe if they can perform routine functions on the interface.
+\begin{itemize}
+\item For example, input correct payment amount or find transaction in account history (see KPIs below).
+\end{itemize}
+\item Novice users:
+\begin{itemize}
+\item we provide a brief orientation ($approx$ 30 mins) to a function
+\item let a day pass
+\item test ability to use the function without help
+\end{itemize}
+\end{enumerate}
+\end{frame}
+
+
+\begin{frame}{Key Performance Indicators}
+\begin{enumerate}
+\item KPIs will include the ability for non-users, after one or more short, standardized briefings and one day, to (without help):
+\begin{itemize}
+\item input a correct payment amount into the correct Taler field
+\item perform a full payment transaction in the Taler wallet
+\item find a previous cash inflow in the payment history
+\item recognize a failed transaction and identify the need to correct it
+\end{itemize}
+\item Experienced users will own smartphones and will have used the app for several weeks. For them KPIs will include the ability to (without any help or orientation):
+\begin{itemize}
+\item Conduct all tasks listed above, more quickly than recently briefed users.
+\end{itemize}
