Some enterprise challenges we encounter

“Doing agile at the team level

is fine. But how do we deal

with the things we cannot get

into the team?”

@yuvalyeret@yuvalyeret@yuvalyeret

@yuvalyeret

Step #1: identify and work with

minimally valuable features

@yuvalyeretLimit the size of work - at all levels

http://www.freefoto.com/images/41/03/41_03_4---Weight-Limit-Sign_web.jpg?&k=Weight+Limit+Sign

















@yuvalyeretVisibility – Monitor and control the size of work

@yuvalyeret

Step #2: Visualize Flow

“We don’t yet have the political

power or resolve to create real

Feature Teams end to end. So

what do we do?”

WIP / Cycle Time / Management Overhead –

Less is Better…

them

@yuvalyeret

Best – Cross-Product Feature Team / Task Force

Let them organize around the work

What does Versatility

mean at Scale?

Try... Reducing the number of different

skill sets, and generalizing some

specializations

@yuvalyeret

@yuvalyeret

“The Pipeline”

@yuvalyeret

No dependencies –

Expand/Collapse

@yuvalyeret

Dependency “Networks”?

@yuvalyeret

What about Coordination at

Scale?

@yuvalyeret

Anyone using Scrum of

Scrum?


Questions about Scrum of Scrum

• Are we doing it because we have

Scrum+Scale? What problem are we trying

to solve?

• Is Scrum of Scrum used for coordinating

100% of the work, or just the exceptions?

@yuvalyeretCoordination at scale

@yuvalyeret


How about Improving at Scale?

• How many of you can name a

process improvement they are

trying this month?


Early Process Feedback and Adjustment

• Lean/Kanban - Improvement

happens as part of flow

• Retrospectives/Kaizen

Events are still important


Try… Operational Reviews

@yuvalyeret

Try… an Improvement Service

@yuvalyeretPull Improvement Needs from Teams

@yuvalyeret

Will visualizing and managing flow in each of

those roads be enough?

@yuvalyeret

Need to visualize and manage the global end to end

flow across shared resources

@yuvalyeret

What about Due Dates and

Commitment?

#AgileIL11

What do you mean tell the

customers to go Agile? Come on!

Be REAL!

Does Flow mean no

commitment?

@yuvalyeret

REAL reason to for Due Dates?

Use Fixed Date class of service
