Does anyone know how I could ask permission to use this useful clip in my personal video for an educational purpose? (I don't see how I could contact "linkmv" shown in the last seconds of this clip.)
In my opinion narrowing down the scope of possible ideas in the first step of a brainstorming process is a little too restrictive...on the other hand I agree that reducing discussions is a big plus. At Zenkit, a start-up which developed a project management tool, we thought about how to find the brainstorm method that works best for you (and your team). The article can be found here: blog.zenkit.com/how-to-make-brainstorm-methods-work-for-you-523b07ff8a28 I would be happy if you take a look at it and share your ideas.
Faulty logic comparing advantages/disadvantages numerically. Some advantages might be critical in either method, it depends on what the group wants to produce as a result of the exercise.
A possible enhancement (or at least, a variation) might be to precede this session with a more 'conventional' brainstorming sesion to free up, prime or seed the participants' minds to get them in the right frame.
Excellent and, to me, original idea. I am impressed that you have admitted its disasvantages. Fo me ir narrows the scope rather early but that may have its positives too and, as you say, it's worth a try. Thanks very much for posting this. I love to learn new things in creativity.
