* Taken from Leading Change by John Kotter - 1996

Your Change-Action Plan
(continued on next slide)

1. Establishing a sense of urgency
- Identifying and discussing Strengths, Weaknesses, Opportunities, Threats
2. Creating the guiding coalition
- Putting together a group with enough power to lead the change
- Getting the group to work together as a team
3. Developing a vision and strategy
- Creating a vision to help direct the change effort
- Developing strategies for achieving that vision
4. Communicating the change vision
- Using every vehicle possible to constantly communicate the new vision and
strategies
- Having the guiding coalition role model the behavior expected of employees

Your Change-Action Plan
(continued from previous slide)

5. Empowering broad-based action
- Getting rid of obstacles
- Changing policies, procedures and structures that undermine the change vision
- Encourage risk taking and nontraditional ideas, activities, and actions
6. Generating short-term wins
- Planning for visible improvements in performance, or “wins”
- Creating those wins
- Visibly recognizing and rewarding people who make wins possible
7. Consolidating gains and producing more change
- Using increased credibility to change all policies, procedures and structures that don‟t fit
the transformation vision
- Hiring, promoting, and developing people who can implement the change vision
- Reinvigorating the cultural renewal with new projects, themes and change agents
8. Anchoring new approaches in the culture
- Creating better performance through customer and productivity oriented behavior, more
and better leadership, and more effective management
- Articulating the connections between new behaviors and original success
- Developing means to ensure leadership development and succession

 Collaboratively and adaptively develop value-
adding product increments in a continuous flow
from requirements to deployment
 Be objective and see things as a whole
 Be value-driven not plan/task-driven
 Identify and continually discuss individual, team
and enterprise strengths, weaknesses,
opportunities and challenges
 Put together a coalition to lead by example and
teach
 Create a vision to help direct change
 Use every vehicle possible to constantly
communicate the vision and strategies
 Get rid of barriers to being agile
 Generate short-term wins
 Develop people who can implement the change
 Anchor being agile in the culture

Manifesto for Agile Software Development

We are uncovering better ways of developing
software by doing it and helping others do it.
Through this work we have come to value:

Individuals and interactions over processes and tools

Working software over comprehensive documentation

Customer collaboration over contract negotiation

Responding to change over following a plan

That is, while there is value in the items on
the right, we value the items on the left more .

Scrum


What is Iterative and Incremental Development?

 The definition of "iterative" is to involve repetition
 Iterative Development is a development approach that "cycles" through a set of
activities, from understanding requirements to incrementally produce and refine
an effective solution
 Iterative Development involves the successive refinement of the solution
definition and implementation by the repetitive application of the core
development activities to incrementally produce and refine an effective solution

Scrum Explained
“The… „relay race‟ approach to
product development…may conflict
with the goals of maximum speed
and flexibility. Instead a holistic or
‘rugby’ approach—where a team
tries to go the distance as a unit,
passing the ball back and forth—
may better serve today’s
competitive requirements.”- Hirotaka
Takeuchi and Ikujiro Nonaka, “The New New Product Development
Game”, Harvard Business Review, January 1986

In Scrum you work in iterations
delivering value-adding results
incrementally

The Product Owner/Customer tells us they want an implement for writing,
drawing, or marking that is easy to keep sharp, is comfortable to hold, and when
they want to they can easily make a correction.

We collaborate more with the Product Owner/Customer on their needs or
requirements and define the implement’s features and corresponding
benefit/value, as depicted in the table below. Take notice that we have benefits
that influence the implement’s functionality and constrain its design and final
form.

Features Benefits/Value
Is made of wood Easy to sharpen and smells good
Has a specific diameter Comfortable
Surface to be coated Won’t get splinters
Contains a lead composite filler Creates an impressive line
Has an eraser at the end Makes correcting easy


• As an implement user I want an implement that is made
of wood so it is easy to sharpen and smells good when
sharpening
• As an implement user I want an implement that has a
specific diameter so it is comfortable to hold
• As an implement user I want the surface of the
implement to be coated so I won’t get splinters when I
use it
• As an implement user I want the implement to contain a
lead composite filler so I can create an impressive line
• As an implement user I want to have at the end of the
implement an eraser so I can easily make a correction

A story is a “placeholder”
for a requirement formulated in
one or two sentences written in the
everyday language of the customer
or user describing desired
functionality; containing just
enough information so that the
product team can produce a
reasonable estimate of the effort to
implement it

As a Customer I
want to review my
order so that I can
verify my address
is correct


Four factors to consider when prioritizing
1. Degree of uncertainty - the amount and significance of
learning and new knowledge gained by developing the
product increment
2. The amount of risk removed by developing the product
increment
3. The value of having the product increment
4. The cost of developing the product increment

Story Points: Relative Measure of
the Size of a User Story
 What matters are the Product Backlog
relative values
 The raw values we assign are
unimportant
 A story assigned a two
should be twice as much as a
story that is assigned a one;
it should be two-thirds of a
story that is estimated as
three story points
 Estimating in story points
completely separates the
estimation of effort from the
estimation of duration

On a Scrum project, the team tracks its progress against a release plan by
updating a release burndown chart at the end of each Sprint.

The horizontal axis of the release burndown chart shows the Sprints; the
vertical axis shows the amount of work remaining at the start of each Sprint in
