W.Edwards Deming

• Scrum is not a

methodology

• Scrum is not a defined

process

• Scrum is not a set of

procedures

Definition of Scrum

The Scrum Guide contains the definition of Scrum. This definition consists of Scrum’s

roles, events, artifacts, and the rules that bind them together

http://www.scrum.org/scrumguides/

• Scrum is an open

development framework with

a simple set of rules

• It has been used to manage

complex product develop-

ment since the early 1990s

• Ken Schwaber and Jeff

Sutherland developed Scrum

The defined process control

model requires that every

piece of work be completely

understood. Given a well-

defined set of inputs, the

same outputs are generated

every time.

Empirical Process Control

Three pillars uphold every implementation of empirical process control:

transparency, inspection, adaptation

http://www.scrum.org/scrumguides/

The empirical process control

model asserts that knowledge

comes from experience and

making decisions based on what

is known. Scrum employs an

iterative, incremental approach

to optimize predictability and

control risk.

Points of Attention

• Documentation

• Management buy-in/commitment

• Cultural aspects

• Risk Management

• Release Planning

• Fixed Price

Release Planning

“Any Product Manager that has successfully

delivered a product to a customer knows how

incredibly important Release Planning is.

Despite its importance, the 2011 Scrum Guide,

published in July by Ken Schwaber and Jeff

Sutherland, removes any discussion about

Release Planning and the related Release

Burndown chart.”

Fixed Price

“Money for nothing and your change for free”
