The Agile Manifesto
We are uncovering better ways of developing
software by doing it and helping others do it.
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.

12 Principles of Agile Software
1. Our highest priority is to satisfy the
customer through early and continuous delivery
of valuable software.
2. Welcome changing requirements, even late in
development. Agile processes harness change for
the customer's competitive advantage.
3. Deliver working software frequently, from a
couple of weeks to a couple of months, with a
preference to the shorter timescale.
4. Business people and developers must work
together daily throughout the project.
5. Build projects around motivated individuals.
Give them the environment and support they need,
and trust them to get the job done.
6. The most efficient and effective method
of conveying information to and within a
development team is face-to-face conversation.
7. Working software is the primary measure of
progress.
8. Agile processes promote sustainable
development. The sponsors, developers, and
users should be able to maintain a constant
pace indefinitely.
9. Continuous attention to technical
excellence and good design enhances agility.
10. Simplicity the art of maximizing the
amount of work not done--is essential.
11. The best architectures, requirements, and
designs emerge from self-organizing teams.
12. At regular intervals, the team reflects on
how to become more effective, then tunes and
adjusts its behavior accordingly.

Origins ...
Scrum
● 1986, Hirotaka Takeuchi and Ikujiro Nonaka described a new approach to commercial product development "holistic
or rugby approach"
● 1991, DeGrace and Stahl first referred to this as the scrum approach. Ken Schwaber used such an approach at his
company, Advanced Development Methods, and Jeff Sutherland, with John Scumniotales and Jeff McKenna,
developed a similar approach at Easel Corporation, and were the first to refer to it using the single word Scrum.
● 1995, Sutherland and Schwaber jointly presented a paper describing the Scrum methodology
● 2001, Ken Schwaber teamed up with Mike Beedle to describe the method in the book "Agile Software Development
with Scrum".
XP - Extreme Programming
● created by Kent Beck during his work on the Chrysler Comprehensive Compensation System (C3) payroll project,
who worked with Don Wells, Ron Jeffries, Martin Fowler and Chet Hendrickson
● takes software development "best practices" to extreme levels
Kanban for development
● Japanese for "signboard"
● Taiichi Onho developed 1940/1950 kanbans to control production between processes and to implement Just n Time
(JIT) manufacturing at Toyota manufacturing plants in Japan.
● 2003, David J. Anderson formulated the Kanban Method as an approach to incremental, evolutionary process and
systems change for organizations
www.torak.com
Scrum
● focus on delivering the highest business value in the shortest time
● allows to rapidly and repeatedly inspect actual working software
● the business sets the priorities & teams self-organize to determine the
best way to deliver the work
● every sprint (1-4 weeks) anyone can see real working software and decide
to release it as is, or continue to enhance it for another sprint
www.torak.com
XP - eXtreme Programming
● improve software quality and
responsiveness to changing
customer requirements
● frequent releases in short
development cycles
● improve productivity and
regular checkpoints with the
customer
● paired programming
www.torak.com
Kanban - 3 basic principles
1. Start with what you do now
● Kanban does not prescribe a specific set of roles
or process steps
2. Agree to pursue incremental, evolutionary change
● continuous small changes that stick vs. sweeping changes that fail due to resistance
and fear in the organization
3. Respect the current process, roles, responsibilities &
titles
● gain support, reduce fear/resistance to change and experience the benefits as a team
Kanban Board
www.torak.com
Kanban - 5 Core Properties
1. Visualize the workflow
● Kanban literally means "signboard" or "billboard"
2. Limit Work In Process (WIP)
● use a pull system - establish and respect your ideal
capacity
3. Manage Flow
● monitor, measure and report the flow of work through each state
4. Make Process Policies Explicit
● describe the process accurately in order to improve it
5. Improve Collaboratively
● using models & the scientific method (empirical) to implement continuous, incremental and
evolutionary changes
Kanban Board

Kanban: Start 1
a
b
to do in process done
Start with a simple task board with 3 columns: to do, in process and done.
Each card represent a work item in the current scope. Names can be associated with
the cards.
The key is to setup an easy way to visualize the work, and create an area for social
interactions.

b
a
to do in process done
A problem with such a simplistic board, is the lack of rules and the concept of time-
boxing.
A typical problem is accumulating too much work in progress (WIP).
Kanban is more than just adding work items on a board, it's also applying a PULL
process.

To truly embrace Kanban, we must regulate the volume of cards on the board. This
can easily be accomplished by identifying clear thresholds associated to better
defined stages of work (columns).
Another improvement is to set a multi-tasking limit per user (2) and using late binding
of tasks to owners. Note that not all team members must have 2 tasks with their
names, this is a maximum of 2.

1. Team member A completes a card
and moves it to the "done" column.
2. Team member A pulls a new card
from the "ready" column and starts
working on it by placing it in the "in
process" column.
3. The team responds to the pull
event and selects the next priority
card by moving it to the "ready"
column.
