Waterfall Model
Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
Waterfall Model best suite for:
Project requirements & objectives are clear, not ambiguous and very rarely changing
Project is large, expensive & complicated, client expect the formal approaches
Project’s cost is pre-defined, fixed-price
Immediate implementation is not required
When resources need to be conserved
Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
History of Agile, Manifesto, 12 Rules
Bureaucratic
Over Regimented
Slow
Difficult to enhance
SD models develop in
1970 – 1990 have
been criticized by
users as:
Industrial Experts / Thought Leaders
Promote innovative approaches to developments
Embracing requirement changes
Continual planning, Empowering teams, Frequent delivery of a
working part
Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
History of Agile, Manifesto, 12 Rules
In 2001, 17 Software consultants gathered to Snowbird, Utah (USA) & defined AGILE SOFTWARE
DEVELOPMENT
Our highest priority is to satisfy the customer through early and
continuous delivery of valuable software
Welcome changing requirements, even late in development. Agile
processes harness change for the customer's competitive advantage.
Deliver working software frequently, from a couple of weeks to a couple of
months, with a preference to the shorter timescale.
Business people and developers must work together daily throughout the
project.
Build projects around motivated individuals. Give them the environment and support
they need, and trust them to get the job done.
The most efficient and effective method of conveying information to and within a
development team is face-to-face conversation
Working software is the primary measure of progress
Agile processes promote sustainable development. The sponsors, developers, and
users should be able to maintain a constant pace indefinitely
Continuous attention to technical excellence and good design enhances agility
Simplicity — the art of maximizing the amount of work not done — is essential
The best architectures, requirements, and designs emerge from self-organizing
teams.
At regular intervals, the team reflects on how to become more effective, then tunes
and adjusts its behavior accordingly
Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
Various subsets of Agile
Scrum is a management and control
process that cuts through complexity to
focus on building software that meets
business needs
Extreme Programming (XP) is a pragmatic
approach to program development that
emphasizes business results first and takes an
incremental, get-something-started approach
to building the product, using continual
testing and revision.
Crystal is a family of human
centric, adaptive, ultralight,
“stretch-to-fit” software
development methodologies
Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
SCRUM Framework
Part of an Agile movement use for product development
Introduced by Jeff Sutherland in 1993 (before describe the Agile)
Project management framework applicable to any project (not only for software)
Project move forward by series of iterations called sprints
3 Roles

Key Roles in SCRUM
Product Owner
Scrum Master
Team
Only one person, Responsible for maximizing
the value of the product

parties.

team when achieving the sprint goal

team, But help to take the decisions
Make sure that everything is happening
according to the scrum process
Self organizing, Cross functional
No sub teams
Software engineers, QA engineers,
Architectures, UI designers etc.
Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
Key Artefacts (1. Product Backlog)
Contain the user stories (sample shows below) written by stakeholders & developers
All the user stories are unimplemented yet, No need to arrange them when starting point
Entire responsible of this backlog is up to Product Owner
Need to arrange the features / user stories according to the priority level, before planning the sprints
Never complete, will change consistently, will become larger when requirements are changing
HR executive assign the salaries to new
employees
HR ex. Select the employee and assign basic
salary, add fixed allowances, deductions &
variable allowances, update data. Sometimes it
is need to assign an entire salary scale.
UI: http://demo.treinetic.com/Rentchefnew
Tester will select employees and enter basic
salaries & other info. Click the update button.
Updated data will display
Name
Description
Screens
How to test
As a HR Executive I can assign salaries to employees
so that useful when preparing pay sheets
Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
Key Artefacts (1. Product Backlog)

Waterfall & Agile – Scrum (By: Gihan Wijesinghe – Professional Software Developer)
Key Artefacts (3. Burn down Chart)
Graphical representation of the project progress with time will indicate here
Updating the burn down chart should done by the scrum master
X axis represents the time by Sprints, Y axis represents the work load by story points (mentioned on PB)
