To acheive social impact, discussing and agreeing on the value of different ideas is crucial. Weighting of criteria for idea selection can help with this.
Best done with an excel sheet or similar.
1 The students decide on a minimum of five criteria that the solution needs to live up to. Here, criteria should be understood as properties/qualities that the solution can fulfill to a greater or lesser degree, and not as requirements that either can be fulfilled or not.
2 Thereafter each of the criteria are weighed on a scale from 1 (least important) to 5 (most important).
3 The students then create a chart or excel where they fill in their weighted criteria with each idea being given between 1-10 points on each of the criteria.
4 When all of the ideas have received points, the points are then multiplied with their allocated weighting. Finally, the total, weighted score per idea is calculated.
5 At this point it is important to reflect whether the idea that has received the most points, is in fact the best idea. This can be a good basis for a discussion about rating criteria and their weighting
6 After having selected 1-3 ideas the students continue with the development and detailing of these ideas.
