Introduction
•Need software management methods to
decrease the cost
•28% completed on time and budget
•23% failed
•49% challenged
•72% not meeting original goals

Waterfall Life Cycle

X

Agile Method
•Continuous attention to technical excellence and
good design
•Self-organizing teams
•Customer satisfaction by rapid, continuous
delivery of useful software
•Working software is the principal measure of
progress
•Delivered frequently

Agile Method (cont)
•Late changes in requirements
•Close, daily cooperation between business
people and developers
•Face-to-face conversation is the best form of
communication
•Time is a fixed variable

Agile Manifesto
“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
•Rugby
•Eight individual
•Move the ball down
the field
•One Goal

Sprints
•Scrum project make progress in a series of
Sprints
•Timeboxed Period (2 – 4 weeks)
•During Sprint, team does:
–Analysis
–Design
–Code
–Test
•Product is potentially releasable after every
Sprint

Potentially Shippable
Product Increment
•At the end of each Sprint, the Team
must produce a potentially shippable
product increment (commit by the
Team)
–High Quality
–Tested
–Complete
–Done

Product Owner
•Represents (or is) the user or customer
for the project
•Knowing what to build and in what
sequence
•Defines goals for overall project

Product Backlog
•The requirements
•A dynamic list of all desired work on the
project
•Prioritized by the Product Owner
•Reprioritized at the start of each Sprint

ScrumMaster
•Responsible for enforcing the values and
practices of the framework and the Team
•Remove impediments
•Educate outside groups about how the Teams
is working
•Improve productivity in any way possible
•Facilitate Team meetings
•Servant Leader

Daily Scrum Meeting
•Tasks that is completed
•Obstacles to complete specific
task
•Plan to accomplish between now
and the next Scrum meeting

Scrum of Scrum
•Synchronize inter-team work
–Issue list is up-to-date
–Discuss impediments

Sprint Planning
•Happens on the 1
st
day of the Sprint
•Scrum Team takes the Sprint Goal and
decides what Product Backlog are
necessary
•Team self-organizes around how they’ll
meet the Sprint Goal
•Sprint Backlog is created

Release Planning
•Several Days before Sprint Planning
•What will be built
•Identify top level priorities
•Select more than what the Team can
likely do in one Sprint

Sprint Review
•Updates to Product Owner
•Plans for next Sprint
–Change in Requirements
•Demonstration

Risk Management
•Risk is low
•Continue testing
•Problem is notified
during Daily Scrum
Meeting

Advantage & Disadvantage
Traditional Management Agile Method
Prioritization + Support for long-term plans+ No delays on important features
+ Less important features might
scaled back or dropped
Planning + Able to see the overall project+ Micro Planning
+ Avoid Requirement cramming
- Might be headed toward wrong
direction
Communication - Lack of communication with the
customer and team members
+ Good internal communication
+ Higher quality
Documentation + Highly emphasize
+ Requires in every stage
- Knowledge is stored mentally
- Code is the documentation
Risk Management - Might not find bugs until later
stage
+ Continuous testing and
communication can find
issues rapidly
