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.

“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.”

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

THERE’S NO VALUE ON THE RIGHT

We have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.

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.

health. In my case: all three.”

“The Devops movement addresses the dysfunction that results from
organizations composed of functional silos. Thus, creating another functional
silo that sits between dev and ops is clearly a poor (and ironic) way to try and
solve these problems.”

“Functional silos allow people to ignore, or at least feel disconnected from, the
consequences of their actions.
Devops is a cultural change that encourages, exposes and rewards people taking responsibility for what they do
and what is expected of them.”

“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.”

“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.”
