know when the product

is estimated to be

delivered.

Unstable environment

just adds costs.

Stable teams get

benefit.

WeatherJeff says that he would

not run a Scrum without

including this Pattern.

Velocity

There’s no such thing as

“Stable Velocity”

When it goes up…

When it goes down…

Running

Average

VelocityUsing running average of

at least THREE Sprints to

calculate the velocity of

next Sprint

Should remember…

One-time event is a part

of life. Do NOT omit it

from the moving

average

Definition of Done

A moving average

accommodates the

increasing accuracy

Updated

VelocityShift gears only after

you’ve established the

ability to crew at a new

level

When that time is…

Update the velocity ONLY

IF a new level is sustained

for the past three sprints.

SwarmingOne-piece continuous

flow

Say goodbye to

multitasking, because…

Multitasking makes you stupid

as well as slow.

Gives the illusion that things

are going faster, but this

increases defects.

–Swarming

“Focus maximum team effort on one item in

the Sprint Backlog.”

“Whoever takes this item is Captain of the

team.”

“Everyone must help the Captain if they can

and no one can interrupt the Captain.”

“As soon as the Captain is done, whoever

takes responsibility for the next priority

backlog item is Captain.”

Illegitimus Non

Interruptus

Scrum teams are often

interrupted during a sprint

The Scrum Team is a critical resource for creating new

software and maintaining old software.

Defects created by the team during a sprint.

www.axon.vnfb.com/AxonActiveVietNam

–Illegitimus Non Interruptus

“Allot time for interrupts and do not allow the

time to be exceeded.”

Three Simple Rules

1. The team creates a buffer for unexpected

items based on historical data.

2. All requests must go through the product

owner for triage.

3. If the buffer starts to overflow, the team should

automatically abort.
