Scrum works by making visible the dysfunction and impediments that are impacting the Product Owner and the team’s effectiveness, so that they can be addressed.
The Scrum framework will quickly reveal these weaknesses. Scrum does not solve the problems of development; it makes them painfully visible, and provides a framework for people to explore ways to resolve problems in short cycles and with small improvement experiments.

It has become commonplace to suggest that failure is good for entrepreneurs. In this view, failure that comes early in a founder's career can teach them important lessons about doing business and harden them up for the next start-up attempt.

In the UK, the evidence is that novices are neither more nor less likely to have a business that either grows or survives than experienced founders. In Germany, where much more extensive statistical work has been undertaken, it is clear that those whose business had failed had worse-performing businesses if they restarted than did novices.

In short, the assumption that entrepreneurs use the lessons of their own experience to improve their chances of creating a series of profitable businesses is not borne out by the evidence. Success in business remains, as in life, something of a lottery.

No matter what humans
think about, we tend to
pay more attention to
stuff that fits in with our
beliefs than stuff that
might challenge them.
Psychologists call this
"confirmation bias."
When we have embraced
a theory, large or small,
we tend to be better at
noticing evidence that
supports it than evidence
that might run counter
to it.
As any psychologist will tell you, pretty much everything you think and do is coloured by biases that you are typically totally unaware of. Rather than seeing the world as it is, you see it through a veil of prejudice and self-serving hypocrisies.

You have just experienced the illusion of naive realism - the conviction that you, and perhaps you alone, perceive the world as it really is, and that anybody who sees it differently is biased.

If, at this point, you are thinking: "Yeah, right, that might be true of other people, but not me," then you have fallen foul of yet another aspect of the illusion: the bias blind spot. Most people will happily acknowledge that such biases exist, but only in other people.

just build a house.

empirical, adjective
based on, concerned with, or verifiable by
observation or experience rather than theory
or pure logic
pertaining to, or derived from, experience
capable of being verified or disproved by
observation or experiment

The "defined" process control
model requires that every
piece of work be completely
understood. Given a well-
defined set of inputs, the
same outputs are generated
every time.
The empirical process control
model, on the other hand,
expects the unexpected. It
provides and exercises control
through frequent inspection
and adaptation for processes
that are imperfectly defined
and generate unpredictable
and unrepeatable results.

Starting from a position of incomplete knowledge and gradually iterating through hypothesis, experiment and discovery towards — one would hope — working software addresses part of the question of moving from the unknown to the known.

If a plot works out
exactly as you first
planned, you're not
working loosely
enough to give room
to your imagination
and instincts.
pantser, noun Writer who writes by the seat of their pants.
In contrast to a plotter, a pantser doesn't
work to (or have) an outline.

TDD is fun! It’s like a game where you navigate a maze of technical decisions that lead to highly robust software while avoiding the quagmire of long debug sessions. With each test there is a renewed sense of accomplishment and clear progress toward the goal. Automated tests record assumptions, capture decisions, and free the mind to focus on the next challenge.

Rock climbing, story-telling, and carpet wrestling are not about winning or losing; the game is all about having fun.
As long as the guessing or the story-telling is interesting, the game is worth playing.
These are cooperative games.
The point of the game is to interact with each other, or perhaps to help each other.

nomic, noun & adjective
a game in which changing the rules of the game is
a legal move and part of the game
the original Nomic was invented by Peter Suber,
but the term is now generalised to describe any
game that has these properties
political constitutions, legal systems, software
development processes and many games that
children spontaneously evolve over an afternoon
of play are nomic in nature
The four conditions that characterize wise crowds: diversity of opinion, independence, decentralization, and aggregation.
There’s little correlation between a
group’s collective intelligence and
the IQs of its individual members.
But if a group includes more
women, its collective intelligence
rises.
