75 -
76 -=== Within Subjects (Repeated Measures) ===
77 -Each participant is subjected to all the test conditions.
78 -Fewer subjects needed and reduces variance in the Can be difficult to setup due to subjects fatiguing, learning about the setup or simply not having enough time.
79 -
80 -=== Between Subjects (Between Groups) ===
81 -One subject undergoes only one test. Simple to execute, but results in significant variance due to inter-subject differences in characteristics.

84 -== Lenses ==
85 -- Lense means to take different perspectives looking at your system
86 -- E.g. perspective of the stakeholders, other groups, or technical/legal
