User-Centred Design Task 3.1 Interview Scenarios The purpose of this document is to provide Interview Scenarios to critique for your Task 3.1. Case Study S1 2019: Energy Shifter This semester you will apply User-Centred Design process and principles to design and build a prototype user interface that allows householders to better understand and make decisions about their energy use to help them to minimise energy bills. SwinSoft interviewed five people to help them understand the context of use for this project. The following is a description of what happened during two of the interviews (see UCD Project Interview Data (resources for Task 4.1, 4.2, and 4.3) for details of what some participants said during interviews).

Make sure you explain why you think it follows guidelines (or not). COS70004 students must include reference to at least one set of guidelines or recommendations (ethical or methodological). For example, Courage and Baxter (2005) recommend that…. However, ….
