Ask HN: Help me finding a video/talk explaining agile problem solving

I am working with an organisation who is looking for input on how to make the switch to agile problem solving and development. Most material out there is quite technical, I am looking for something that business people can understand and relate to; particularly conversative managers who have worked in the same operations environment for 25+ years. Any ideas? I have watched Peter Biddle's TED talk about how to do agile in a large organisation, but it doesn't really cut it.

Key themes I am looking for:

* The concepts of the agile mindset * Plan to fail * Impartial knowledge vs perfect knowledge * Predictability vs change * How agile teams work

Any help would be greatly appreciated -- I am sure you have been facing the same challenges.
