  1. Your quest is to find the Warlock's treasure, hidden deep

    within a dungeon populated with a multitude of terrifying monsters. You will need courage, determination and a fair amount of luck if you are to survive all the traps and battles, and reach your goal — the innermost chambers of the Warlock's domain. Two dice, a pencil and an eraser are all you need to make your journey. YOU decide which route to follow, which dangers to risk and which monsters to fight. Tuesday, 1 October 13

    within a dungeon populated with a multitude of terrifying monsters. You will need courage, determination and a fair amount of luck if you are to survive all the traps and battles, and reach your goal — the innermost chambers of the Warlock's domain. Two dice, a pencil and an eraser are all you need to make your journey. YOU decide which route to follow, which dangers to risk and which monsters to fight. Tuesday, 1 October 13
  3. “Many so-called Agile adoptions, being merely the thinnest of veneers,

    rather than a change of any substance, can lead to a situation where formal controls - i.e. the conventional path to quality - is abandoned without the adoption of any viable alternative path to quality.” Bob Marshall Tuesday, 1 October 13

  6. “Mastery resists definition yet can be instantly recognized. It comes

    in many varieties, yet follows certain unchanging laws. It brings rich rewards, yet it is not really a goal but rather a journey.” Tuesday, 1 October 13
  7. Instruction - find the right guide to take you on

    your journey Practice -the joy of learning and improving through repetition Surrender to Your Passion - love it or leave it Intentionality - visualize the outcome Go to the Edge - go a little bit further than we’ve gone before and maybe even further than anyone else has gone Tuesday, 1 October 13

  10. We have come to value: Individuals and interactions over processes

  11. Manifesto for Devops Ineptitude We are uncovering better ways of

    misunderstanding and misusing “agile” principles by doing it wrong and helping others do it wrong. Through this work we have come to conclude that we should have: Manadatory devops tools to enforce individuals and interactions. Infrastructure as code, with little or no documentation. Naive trust supported by hand-wavey verbal agreements. No plan at all, because we’re “lean” and “agile” hipsters. That is, while there is wisdom in the Agile Manifesto, we failed to understand its essence and implemented a botched mockery in its place. Tuesday, 1 October 13

    to go away and have a little relaxation… When you come back to the work your judgement will be surer, since to remain constantly at work will cause you to lose the power of judgement.” Leonardo Da Vinci Tuesday, 1 October 13
  17. “Creating the label `lean` (what it is) leads naturally to

    and already taxed energy on other people’s priorities, while their own priorities fall to the wayside.” Tuesday, 1 October 13
  27. “If you think it looks like it’s going to be

    slow and expensive, it probably will be slow and expensive, and someone has to pay. If you're not transparent about that, the chances are you'll pay yourself, with lost profit, lost reputation, or lost health. In my case: all three.” Stephen Nelson-Smith Tuesday, 1 October 13

  31. “Functional silos allow people to ignore, or at least feel

    than because we get the wrong solution to the right problem." Russell Ackoff Tuesday, 1 October 13
  38. “We chase the latest ideas in software development without bothering

    with the scientific method. We think it is a waste of time to understand the theory, create hypotheses, run experiments, gather data, and find out what really works in our environment. We fail to appreciate that “best practices” are somebody else’s solutions to their problems, not necessarily the right solutions to our problems. We adopt new development approaches with an unhealthy dose of wishful thinking, rather than determining the most appropriate practices for our environment — and then we are surprised at the disappointing results.” Tom & Mary Poppendieck, Leading Lean Software Development Tuesday, 1 October 13

    news." John Seddon Tuesday, 1 October 13

  41. “Lean downhill when skiing. That takes a certain amount of

  42. “I must not fear. Fear is the mind-killer. Fear is

    the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain.” Bene Gesserit Litany Against Fear (From Frank Herbert's Dune Book Series) Tuesday, 1 October 13
