Then I looked a little closer, and noticed that this section was sheduled for 15 minutes brainstorming, and 30 minutes discussion.
Well guys, I thought - you're not going to get anything of value in 45 minutes.
For a decent sized project like this one, I generally allow 20 minutes or more per person when deciding how long to spend on lessons (in a Retrospect, for example). So say there were 12 people in the room, that's 4 hours. 15 people would be 5 hours.
You need to identify, rank and group the learning points - there's your 45 minutes gone already. Then for each one you have to analyse
- what actually happened
- the root causes behind what actually happened
- what you are going to change as a result
- and the actions that arise.
If you skimp in the time you allow for learning, you never got to root cause, you don't even find out what really happened, and you end up with a set of anodyne bullet points that are no use to anyone.
If you only have 45 minutes, folks - don't even bother to try. If it's worth doing, it's worth doing well, and it's worth taking the time. The corollary to this is that if you don't spend the time and don't do it well, people get the message that it's not worth doing at all.
So you dont have the time to do your learning well, then don't do it at all - you will only devalue the entire process.
