Try different ways

Team missing information Knowledge not distributed

! ernoaapa

Sharing the information is not easy

you cannot force other to learn

! ernoaapa

1 Minimize amount of information

2 Remove unnecessary, automate rest

3 Rotate roles and tasks

4 Repeat, Repeat, Repeat!

5 "Can you do this...?" - "NO! But I'll teach"

Changing culture is not easy
