Sample evaluation grid. Sample evaluation grid from the 'Comparative Analysis and Study Environment' (CASE) software framework. For each question 1 through 7 the circles display researchers’ collective consensus score (+/−) of each case (for example, Q3 concerns control and ownership of resources). In the center of each circle is the total number of evaluators; the pie chart shows the degree of consensus - all positive (green), mixed and all negative (red) (yellow indicates a sub-question that is not applicable); a black outline represents interpretations or comments added by the evaluator. Cases can be re-sorted by question (Q2.1 and Q3.1 are sub-questions).
