The Truth About GTD Software Tools

I just found a David Allen email newsletter I received on this topic back on 7/3/19. Subject line: David Allen on the Best Software for GTD. Here’s the link to that newsletter piece, in which he posts his actual handwritten notes on his ideas, and even invites potential developers to contact his CTO directly via email:

I’ve applied Lean Six Sigma principles to my GTD setup and reached something quite close to what I’d call a personal airtight system.

I'm really curious about what materials you used to learn Lean Six Sigma principles, as I'm not very familiar with it yet. Could you recommend any books or videos?

Maybe like these?
《The Machine That Changed the World》 – James P. Womack, Daniel T. Jones, et al.
《Toyota Production System》 – 大野耐一（Taiichi Ohno）

Thank you!
