Software engineering
is the application of a
systematic, disciplined, quantifiable
approach to the development,
operation, and maintenance of software

 Project Websites were few and far between
 No interest was taken to keep it updated
 Mainly for dashboards and reporting purposes
 Huge amount of Documentation
Not updated regularly

RoI of such documents was not high

Dissemination to team members was a challenge

Version control issues

 Publishing of Information was a lengthy process
 Not much participation
 Folders-based content
 Difficult to mine for relevant info

Web 2.0
 Is a trend in World Wide Web technology, and web
design,
 Is a second generation of web-based communities and
hosted services such as
 social-networking sites,
 wikis,
 blogs,
 folksonomies
 Aim to facilitate creativity, collaboration, and sharing
among users.

Web 2.0 is a
knowledge-oriented environment
where human interactions generate content
that is published, managed and used
through network applications
in a service-oriented architecture

All necessary information is
available on the internet
If it is not, it is not tagged or filed

Methodologies

 Management of knowledge becomes easier
 The social factor - ‘Contribute and share’ is key
 The cool factor - ‘Everyone is doing it’
 Most tools are open-source – hence, no cost
 Multiple ways to categorize same content
 Easy to search
 Easy process to setup
 What are the Web2.0 technologies you use?
 Slides follow…

 Project-wide initiative  Organization-wide
initiative
 Availability of “Live“
documents  Utilize knowledge

 Facilitate collaborative
organization
information gathering
 Capture Information
that can be used in
future

 Instant notifications  Can be Internal/
 Managers/Leads share

information
 Tool for dissemination
 Makes life more
disciplined
in distributed envt.
 Sources of invaluable
information

 Avoid reinventing the wheel
 Provide a searchable repository that can help
locate solutions based on others experience
 Easy to share with entire team

 The technologies of Web2.0 makes a developer’s life
much easier
 Covers all phases of Software Engineering
 Applicable both to Waterfall or Agile
 Information specific to a technology is available on the
internet
 It requires some effort in finding and tagging it
 Information specific to a project can be created quickly
 Distribution is possible at the click of a button
 Improves the overall productivity of the team
