Bundling Ideas encourages you to cluster similar ideas together, identify the best aspects of those ideas, and then combine different clusters of ideas into bundles. These then become themes that can use to start building concepts. As IDEO suggest in their Design Kit: “Think of it as a game of mix and match, with the end goal of putting the best parts of several ideas together to create more complex concepts.”

Once you have bundled your ideas into themes, it is time to judge which ones you want to take forward. Narrow the Set involves agreeing criteria to assess the ideas before ranking or judging them. You can use the design criteria in your Challenge Brief as the basis for your assessment, supplemented by any additional criteria you may have hit upon during ideation activities. Frog Design’s Collective Action Toolkit provides some further guidance on carrying out this activity on p50.
