Does quality matter?
Depends on who you ask... and who
ends up paying for the lack of it.

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.

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."

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

“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)
