The experts say...

Uncle Bob: Much has been written about the hyper-productive state known as “flow.” Some programmers call it “the Zone.” It is the highly focused, tunnel-vision state of consciousness that programmers can get into while they write code. In this state they feel productive. In this state they feel infallible. Here’s a little hint from someone whose been there and back: Avoid the Zone.

Kahoot.it - Question 09

Do you use the best tools money can buy?

Cost of applications – per coder

€ 0 € 100 € 1000 € 10000 Compilers IDEs Compilation tools Modeling tools (Static) code analysis Frameworks 2 hours per year 1/2 week per year 5 weeks per year Return On Investment: (usually yearly)

The one cost all IT depts complain about?

Kahoot.it - Question 10

Do you have testers?

Joel: 5 wrong reasons you don’t have testers

1) Bugs come from lazy programmers. 2) My software is on the web. I can fix bugs in a second. 3) My customers will test the software for me. 4) Anybody qualified to be a good tester doesn’t want to work as a tester. 5) I can’t afford testers!

Kahoot.it - Results

How did “we” score?

Joel (in 2000):

• A score of 12 is perfect,

11 is tolerable, 10 or lower and you’ve got serious problems.

• The truth is that most software organizations are

running with a score of 2 or 3, and they need serious help

• The 040 region is consistently better than a 2 or 3

… Right?

Missing Questions?

• Are you valued?
• Can you express your creativity?
• Do you have more architects than coders?
• Do your architects do better powerpoint than C++?
• Can you work from home?

Take away:

• Profesionalism

– Is in your skills – Is in your tools – Is in YOUR TEAM’s Attitude

• Improve communication
• Improve on your impediments
