7. Make yourself replaceable!
ernoaapa

8. Refer to putting one thing or person in
place of another
replaceable
/rɪˈpleɪs/

9. No time
for learning
and
innovation
Repeat same
task over and
over again
No progress
in your career
High risk to
become
unemployed
You might
undermine
whole
company
irreplaceable
ernoaapa

10. Being IRREplaceable is not good to you
• No time for learning because you use all your time doing
same task over and over again
• You don't develop because you don't have time for learning
and innovation
• You don't progress in your career because you company
cannot move you off from the task
• You become useless when product/service get changed
and your tasks disappear
• You end up being unemployed with outdated knowledge of
some legacy system what no one needs

11. IRREplaceable is not good for company
• Your business is very vulnerable - what if that guy dies?
• That guy can use that to require high salary
• Company knowledge doesn't grow and you end up having
outdated tools, practices and technologies
• Company doesn't innovate and get stuck on single legacy
solution what new companies can outdo

12. Share your knowledge Share responsibility
Time for
innovation
You become
more productive
ƔImprove the process
Teach others
to solve the problems

14. How I did cut off
-80%
operation work?
20%
ernoaapa

15. - 20% Remove all unnecessary
-20%
Remove legacy servers
Switch to cloud services
Remove all
"I might need some day" -code
Clean up duplicate code
ernoaapa

16. -30% Simplify, SIMPLIFY But dont over-Simplify!
-30%
Simplify technology stack
Remove legacy technologies
Split service to smaller pieces (micro
services)
Remove rarely used features
Refactor codebase
But DON'T force single technology
stack!
ernoaapa

17. - 30% Make your self replaceable
-30%
Automate your work
Push responsibility to the team
Teach everything you know to at least
two persons
Make sure team can work without you
