A quick overview of modern Software Development Methodologies.

1. VALUE-DRIVEN APPROACH TO SOFTWARE
DEVELOPMENT

2. Heavyweight methodologies support comprehensive
planning, detailed documentation, and expansive
design.
HEAVYWEIGHT/WATERFALL APPROACH

3. WATERFALL APPROACH: PROS AND CONS

4. Studies have shown that in over 80% of
the investigated and failed software
projects, the usage of the Waterfall
methodology was one of the key
factors for failure.
For example, in one key study of 1,027
IT projects in the UK, Thomas [2001]
reported that "scope management
related to attempting waterfall
practices was the single largest
contributing factor for failure".
The high ranking of changing business
requirements suggests that any
assumption that there will be little
significant change to requirements
once they have been documented is
fundamentally flawed, and that
spending significant time and effort in
fighting the to maintain the maximum
level is inappropriate.
WHY WATERFALL APPROACH IS SLOWLY FADING OUT

5. Agile methodologies employ short iterative cycles, and
rely on driving business value and tacit knowledge within a
team as opposed to documentation.

6. AGILE APPROACH: PROS AND CONS

7. • Agile methodologies, have gained
significant attention from the
software engineering community in
the last few years.
• Practitioners are making the switch
to this evolutionary model because
of its fast and flexible way to
developing software; based on
principles of collaboration,
adaptability and continuous
improvement.
WHY AGILE APPROACH IS QUICKLY TAKING OVER

8. Enables active user
involvement
Team is
empowered to
make decisions
Requirements
evolve under a
fixed timescale
Requirements are
captured at a high
level; lightweight &
visual
Releases are
developed in small,
incremental
iterations
Focuses on frequent
delivery of quality
products
Testing is integrated
throughout the
project lifecycle –
test early and often
Encourages
collaborative &
cooperative
approach between
all stakeholders
