20. Fear of change
fear of beeing transparent
➧ avoid giving any meeting the look like
they are in place for reporting
unwilling to take over
responsibility
➧
let the team make decisions
themselves and hold them
accountable for them.
„Nonsense“
Disregarding the benefits
➧
Scrummaster must facilitate.
Teams are recognizing the benefit
fairly quickly.
That does not fit the way we
work
➧
search for Interfaces/interactions that
allow to fit in, but don't compromise
on the Rules (see 2nd comment)
Talk, Talk, Talk…
… do retrospectives on regular base and try to reduce the fears.

21. afraid of making
mistakes ➧ Mistakes are expected! Repeated mistakes are unwanted.
to say "No"
➧ accept a „No", take away pressure,
create transparency of what's the real velocity
not getting it done
➧
solving technical debt will result in a lower velocity. Let people
get a feeling of their own velocity and accept commitments
but also demand those commitments.
to change processes
that remained
untouched a long time ➧ Convince people of the benefits and empower them
Change with no fear

Friday, April 26, 13

23. Prepare Management
➡ let the Boss/Client FEEL the improvements
➡ learn how to handle the reporting tools to
avoid a bad gut feeling
➡ handle Uncertainty = reporting-artefacts in
scrum are sufficient enough!
➡ enforce lean management
Friday, April 26, 13

24. Don't lie to yourself!
➡ We certainly moved and changed (after the first sprint)
➡ We "adjusted" the scrum process to fit our organization.
➡ enough change, we need to work now.
➡ the Teams are delivering new features constantly but we had to
employ a new bug-manager.
Friday, April 26, 13
