6. What's a Kayak
● Small human-powered boat
● Use “Paddle,” not “Oar.”
● Oars are attached on a boat to use the principle of
leverage (easy to move, but no freedom).
● Paddle is not attached on a boat because of FREE
Maneuverability

9. Anyway, I said,
● “Kayaking is Good training to improve your
’Human’ skill of IT engineer!”
● What do I mean?
● Just a hobby?
● My opinion is:
● Of course, we play kayak as hobby, but,
● Kayaking (especially whitewater river running) has
very similar points with software developments
● Mostly HUMAN SKILLs

10. Example:
Upper Kidu-river, MIE prefecture

11. SCARY?
YES, REALLY SCARE.
Calm down, calm down, calm down...

12. Don't scare, LOOK and THINK!

13. Find your OWN route
There is
a big rock!
It's my route
(and succeed!)
Big drop and
very shallow...

14. Manage YOUR Risks
● White water paddling is very nice training of
RISK MANAGEMENT (not for your mgr.)
1.Find ALL of risks you have
2.Classify which risks are acceptable
NOT SO SERIOUS SERIOUS (DEATH?)
Can avoid?
Everyone (Not a risk)
Easy Acceptable (Fun!) Don't try!
Difficult Acceptable if you want Don't try!
3.Then, decide which route is best for yourself.
– The best routes are different for each people.
– Paddling skill, kind of boat, mental (big factor),...

15. More important thing:
● Teamwork!
● given enough eyeballs, all risks are shallow.
– Modified Linus's Law (bugs → risks)
● For good classification of risk, need many heads.
● In trouble, your buddies will rescue each other.
– The trust braves you to beat risks!
Thinking, Judging, Trust and Success together
make very good teamwork,
It is exactly same as software developments,
isn't it?

16. Once Again:
● Kayak is very nice hobby for IT engineers!
● Good recreation
in nature,
of course
● Fun, very fun.
● And, Good training
to improve your
’Human’ skill of
IT engineer!

17. Play Kayak
for your good
Engineer's life!
