4. Disadvantage of traditional SDLC
Always Delayed Deployment to real time world,
impacting customers business.
New Requirements and Change Requirements are not
considered in immediate builds.
Customer’s feedback and inputs on AUT are possible
at a very later stage of SDLC.
Incomplete Documentation, Complete documentation
is a complicated and a time consuming task.
5. What is Agile?
A group of software development methods based on
iterative and incremental development, where
requirements and solutions evolve through collaboration
between self-organizing, cross-functional teams.
6. Agile Manifesto
Individuals and interactions over processes and tools
Working software over comprehensive
documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

12. Types of Agile
Agile Unified Process (AUP)
Crystal Clear
Dynamic Systems Development Method (DSDM)
Essential Unified Process (EssUP)
Exia Process (ExP)
Extreme Programming (XP)
Feature Driven Development (FDD)
Kanban (development)
Open Unified Process (OpenUP)
Scrum
13. Scrum Basic
Roles: The Product Owner, who is responsible for the
business value of the project;
the Scrum-Master, who ensures that the team is functional
and productive;
and the self-organized team.
Ceremonies: the sprint planning meeting, daily roles,
“Scrum is made up of three
three ceremonies
scrum meeting, and sprint review meeting
and three artifacts.”
Artifacts: the product backlog, the sprint backlog,
and a burn-down chart
15. Burn down Chart
A burn down chart is a graphical representation of work
left to do versus time. The outstanding work (or backlog) is
often on the vertical axis, with time along the horizontal.
16. The pre-requisite soft skills for a Scrum Team
1.Team Spirit
2.Communication
3.Commitment
4.Problem Solving
5.Transparency
“ Team can deliver high value software features in a short time
period
18. Estimating Size with Story Points
• Story Points Are Relative
– Raw value not important but Relative is.
3
1
2
– Two common ways to get started
Pick the smallest story then assign 1 point
Pick the medium-size story then assign 5
points
19. Estimating Size with Story Points
• Velocity
– A team’s rate of progress.
– Total story points completed during the
iteration.
3 3 completed
5 5 not finished
3 3 not started
2 2
IT1 IT2
Velocity = 13 Velocity = 8
1 week 1 week
– Size = 100 points & Velocity = 10 & 1-Week
Iteration, we need 10 iterations, which equals
10 weeks on the calendar.

At any time the status of the project is visible for everybody

Multi disciplinary teams are located on one
“Dinning table” (PM/BAs/QAs/DEVs)
