Waterfall Development is
another name for the more
Waterfall Development

You complete one phase (e.g. design) before moving
on to the next phase (e.g. development)
You rarely aim to re-visit a ‘phase’ once it’s
completed. That means, you better get whatever
you’re doing right the first time!

• Is there any problem ?

This approach is highly risky, costly and
generally less efficient
You don’t realize any value
until the end of the project
You leave the testing until the
end
You don’t seek approval from
the stakeholders until late in the
day
But… REQUIREMENTS

the most important factors
that you need to consider are
the people and
how they work together
A fool with a tool is still a fool.

Never forget that the primary goal of
software development is to create software,
not documents !
Otherwise it would be called
documentation development wouldn’t it?
When you ask a user whether they would want ??
A fifty page document describing what you intend
to build ?
or
The actual software itself, what do you think
they’ll pick?

Remember!!
Only your customer can tell you what they want

Remember!!
Nothing ever goes entirely on plan
but instead of sticking with something that
isn't working
It's much more effective to make adjustments
as your situation changes

Following the values isn't always easy
But when you build them is your team's processes
You will definitely get a better software project

Hmm..
So , Is that It ?

Sure No !!

The four core values are illuminated
by
12 principles of Agile software
development.

“ Our highest priority is to
satisfy the customer through early
and continuous delivery of valuable
software. ”
Principle
#1

“ Welcome changing requirements,
even late in development.
Agile processes harness change
for the customer's competitive
advantage.”
Principle
#2

“ Deliver working software
frequently, from a couple of weeks to
a couple of months, with a preference
to the shorter time scale. ”
Principle
#3

“ Business people and developers
must work together daily throughout
the project. “
Principle
#4

“ Build projects around
motivated individuals. Give them the
environment and support they need,
and trust them to get the job done. “
Principle
#5

“ The most efficient and effective
method of conveying information to
and within a development team is
face-to-face conversation.“
Principle
#6

“Working software is the
primary measure of progress. “
Principle
#7

“ Agile processes promote
sustainable development. The sponsors,
developers, and users should be able to
maintain a constant pace indefinitely. “
Principle
#8

“ Continuous attention to
technical excellence and good design
enhances agility. “
Principle
#9

“ Simplicity – the art of maximizing
the amount of work not done ,
is essential. “
Principle
#10

“ The best architectures,
requirements, and designs emerge from
self-organizing teams. “
Principle
#11

“At regular intervals, the team
reflects on how to become more
effective, then tunes and adjusts its
behavior accordingly.“
Principle
#12

Scrum
• Scrum is an agile process that allows us to focus on delivering the
highest business value in the shortest time.
• It allows us to rapidly and repeatedly check actual working
software (2 – 4 weeks).
• The business sets the priorities.

Scrum characteristics
• Self organizing team to determine the best way to deliver the
highest priorities features
• Product progresses in a series of month-long “sprints”
• Requirements are captured as items in a list “product backlog”
• Uses general rules to create an agile environment for delivering
projects

Scrum sprint
• Scrum projects make progress in a series of “sprints”
• Typical duration is 2–4 weeks
• Product is designed, coded, and tested during the sprint
NO Changes During Sprint !
