My invited talk at ITREND2011

1. Don’t Fear Change,
Let Change Fear You
by Zsolt Fabók
November 17, 2011

3. What do you think was the biggest
development budget I’ve seen spent on a
project where the result was never used?

4. It was more than
576 000 EUR!
(in 6 month)

5. Project’s vision Business needs

6. They follow different paths

7. My definition of change:
“The effort an organisation
has to make in order to pull up to
the actual business needs”

8. The size of the change is
determined by two factors:
ss ti on
change
ine ec
u s d ir
b speed

p ro

9. The first thing to identify in order
to find the right direction, is your
real customer!

10. Walmart lost millions of dollars
because it followed the feedback of the
wrong customers

11. See how the customer uses the product

12. After spending 2 days with the
customer my former colleague found
out that 87.5 % of our features
were not used

13. Google
analytic
heatmap s for web
/apps
A/B testing

14. My friend whose app has over 250k
downloads at android market does not
waste even 1% on features, nobody
interested in, and has >4.5 overall ratings

15. Now we know
where to go,
let’s speed up!

16. Kanban provides the system, so that he’ll
reach his target faster (way of working)

17. Thanks to Kanban, I know exactly what happens
in the organisation:

19. eXtreme Programming provides the certainty
so that these nice baskets won’t fall down while speeding up
Testing and
fast feedback

20. As a result of 6 month long small
investment, we can now find out
the effect of any kind of change in
our system in 7 minutes

21. Pair programming really pays off:
Defects introduced in 3 months with my old team

22. If you know your customer, and you
already have started to implement
Kanban and eXtreme
Programming, then you can rest,
don’t worry about changes ;-)
