Where do we start?

@DanaPylayeva

Examine your system- does it look like this?

Systems

thinking –

focus on

improving

the flow of

work through

organization.

The flow-of-time Clock, Bernard Gitton . Europa Center, Berlin

Theory of constraints - Systems thinking.

1.Identify the system's constraint(s)

2.Decide how to exploit the system's constraint(s)

3.Subordinate everything else to the above decision

(align the whole system or organization to support the

decision made above)

4.Elevate the system's constraint(s) (make other major

changes needed to increase the constraint's capacity)

5.Rinse and Repeat:

Warning! If in the previous steps a constraint has been

broken, go back to step 1, but do not allow inertia to

cause a system's constraint.

Deployments automation.

@DanaPylayeva

Small batch sizes. Virtualization.

The Three Ways:

“The First Way, helps us understand how

to create fast flow of work as it moves

from Development into IT Operations,

because that’s what’s between the

business and the customer.”

@DanaPylayeva

The Three Ways:

“The Second Way shows us how to

shorten and amplify feedback loops, so

we can fix quality at the source and avoid

rework. “

@DanaPylayeva

The Three Ways:

“The Third Way shows us how to create a

culture that simultaneously fosters

experimentation, learning from failure,

and understanding that repetitions and

practice are the prerequisites to

mastery.”
