Overheard this saying from Cynefin Basecamp Nov 2023

I haven't connected to the idea that some tools are not effective in complex domain. It's a good reminder that when I'm about to employ a certain tools or techniques, they might be less effective in Complex domain. This is probably why Complex facilitation is required.
