Prepare the Team

➡ has to have the strong willingness to change something

➡ has to take over responsibility &

➡ has to be aware of being held accountable

➡ might also reject changes

Keep in mind: Initially Scrum was meant for hyper-performant teams!!Friday, April 26, 13

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.

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

Have A Transition Team:

➡ Drives change throughout the whole organization

➡ „Powerful“ Support for the ScrumMaster

➡ Defines Interfaces between departments

➡ Creates transparency throughout the company

Friday, April 26, 13

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

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

➡ Create a sense of urgency

➡ Create the guiding coalition

➡ Develop a vision and a strategy

➡ Communicate this vision

➡ Empower employees for broad-based action

➡ Generate short-term wins

➡ Consolidate the gains and produce more change

➡ Anchor the new approaches in the culture
