47	47	First we need to determine usability for different groups, identify good and bad features for future design. Compare the design choices for making decisions and observe the effects. We need to use this final step to evaluate what to do better. As people's interests change over time, there is a constant need for reiteration of the product. In SCE specifically, we focus on checking the usability of the interaction design at the task level.

51	51	There are formative and summative evaluations. They both intertwine, because we need to observe how people interact with the system and based on that we can evaluate other properties, such as whether they are able to do the interaction we designed. By understanding how they interact with the system we can make different design choices to allow people to perform the interaction based on "logical" choices we observed.

55	55	Formulative evaluation is derived from open questions in the design specification.
56	56	Summative evaluation is derived from closed questions in proving the quality of the design. Summative evaluation also uses independent variables which we manipulate to measure the effects (dependent variables).

58	58	**Know about basic data type constraints**
	57	+We need to consider which tools to use (GDPR), where we can gather much data (crowd sourcing) and how to ensure that our data is of quality (attention checks or multiple questions related to same construct).
