Depends on who you ask... and who

ends up paying for the lack of it.


Are we any good?

From an objective POV (?)

CHAOS Report 2012

We have been analyzed…

The findings…

If we have good people

• who know what they are trying to achieve

• with true involvement

• with good communication with who they’re

achieving it for

• who are well-supported

they will succeed, if success is possible.


Learning

There’s no substitute for learning on

the battlefield.

Enterprise Architecture "a well-defined practice for conducting

enterprise analysis, design, planning, and

implementation, using a holistic approach at

all times, for the successful development and

execution of strategy. Enterprise Architecture

applies architecture principles and practices

to guide organizations through the business,

information, process, and technology changes

necessary to execute their strategies. These

practices utilize the various aspects of an

enterprise to identify, motivate, and achieve

these changes."

Hack.


Hackers?

“A hacker is someone who thinks outside the box. It's

someone who discards conventional wisdom, and

does something else instead. It's someone who looks

at the edge and wonders what's beyond. It's

someone who sees a set of rules and wonders what

happens if you don't follow them. A hacker is

someone who experiments with the limitations of

systems for intellectual curiosity.” - Bruce Schneier, Secrets and Lies, 2000

The importance of never being done

And make sure programming is fun enough.



“I've come to believe deeply in the

idea that that becoming a great

programmer has very little to do

with programming.” - Jeff Atwood (2011)
