ABSTRACT
Continuous improvement is based on balancing what we desire with the practicalities of time and effort. Continuous improvement gives us control of our changes and our situation, guided by feedback and reflection. But change is not always ours to control and, if we are honest, some changes are better carried out discretely than discreetly.
Change from outside can arrive gradually and then all at once. It can be a surprise because we could not have known, or it can be a surprise because we chose not to know. Most changes described as disruptive were there all along and, in truth, are only disruptive because of attitude and entrenchment. But whether the change forced upon is sudden and catastrophic because it is sudden and catastrophic or simply because we didn't know better, we may find that evolution is forced upon us.
How can we respond? [...]

'The decision to use LESS and SAFE it's a public admission that we don't have what is needed to be agile, so we choose brand", I loved it!
Essentials revisited. Very enjoyable. Thank you.
Thank YOU for the talk!
Added to my top ten talks
quantum computing at its best!
Love the physics metaphors!
I feel like the discussion of velocity misses out the most glaring problem with attempting to optimise for "velocity" as measured in story points per month. It's not that by velocity we mean speed - that's fine, optimising speed is still good. It's that it's not any sort of meaningful measure of speed, because "story point", has no set definition that's anything like specific enough to allow comparing velocity of one team with velocity of another, or even velocity of one team with velocity of the same team after a velocity improvement effort.
I realise it's nitpicking, but for humans walking is not inherently stable. We're not stable standing on one leg. We're not even particularly stable on two legs except by actively stabilising ourselves. To be inherently stable walking on point feet you'd have to have four, and just lift one at a time so that any moment you have three feet on the ground around the point below your centre of mass.
When we walk in a relaxed way we lift up a foot and then fall forward onto that foot.
We can walk in a stable way, it's just very unnatural. But you can extend your leg, put it down, and only then transfer your weigh - this way skipping the moment where your falling.
Perhaps it would be better to say that when walking you're always grounded. You know where you are and you can stop or change direction at any moment. Once both or feet leave the ground, we no longer control our direction - we'll land where we'll land.
