#1 Team Involvement - Sooner the better
• The test team was involved right from the initiation &
planning stage
• Test strategy formed during the initiation stage.
• It contained the high level approach on how
system shall be tested
• It also contained the responsibilities of the testers
within the team at different stages of the project
• For estimations and planning along with the business
and development teams, testers were also involved
• Early involvement helped testers in understanding
business perspective and dependencies better

#2 Divide and rule
• Instead of trying to fit all types of tests within an iteration,
division based on types was done
• Testing within an iteration
• Feedback provided by business, UX team & testers
• Unit testing & Integration testing (by developers)
• Functional testing (by testers with guidance from BA)
• Regression testing (by testers)
• Testing outside an iteration (stabilization)
• Performance testing
• Security (ethical hack) testing
• Final UAT & Regression testing
• Exploratory testing by business and legal teams

#3 Work together as a team
• Though there were multiple vendors spread across
different locations and time zones, the cross-functional
team worked as a cohesive team
• The scrum master had to be on a constantly look out
for any team behaviors which can result into group-ism
and arrest the behavior at the start
• Collaboration tools like net meeting, VCON, TCON
were extensively used
• Some of the key team members in the team – team
leads, sr. developers, testers, BA came together at same
physical location for planning and initial iteration of the
program

#4 Code will change.Accept it.
• Testers typically test on a code which is fairly stable
• When an iteration is 2 weeks long, there are code changes till
the last day of the iteration
• There were challenges in changing the mindset of the testers
that the code undergoing test is going to change frequently during
development of the iteration
• During iteration
• At end of the day, developers provided links to their code
from the development environment which the testers used
to provide feedback on.
• This was considered as feedback & not defects as the
iteration was work in progress
• At end of the iteration which ever feedback was not
addressed was entered as defects in the Quality Center by
the test team
• Test team was responsible for collating the feedback from
business and UX teams as well

#5 Readiness checks are necessary
• Agile does not mean that the checks or sign-off are no longer to be taken by the test team
• Within an iteration
• Review were done by the BA and business on the test cases and test plan to ensure
coverage
• “Done” ness criteria was established for tracking the iteration completeness.
• “Done” ness criteria also included the compliance and security checks
• Outside an iteration
• Readiness criteria to move from one environment (integration -> staging ->
production) was established by the test team

#6 Do not forget to measure
• Monitoring of metrics is important. Especially for a large program
• HP Quality Center was used as the test management tool
• Following metrics were captured
• Within an iteration
• Defects which are not addressed and carried forward in an iteration
• Test cases and scripts that were completed and on which environment
• Out side iteration
• Defect spread based on priority
• Test scripts % execution
• Test scripts % passing

• The teams – business, BA, test, developer belonged to different groups within the organization
• There was a need to establish a strong governance structure which was agreeable to various
stakeholders involved
• This was not finalized by the time the program started and hence there were issues seen during
the initial iterations
• The PMO was made aware of the process to be followed. They provided the by-in on the
process and artifacts that were produced as part of the agile process
• Learning from retrospective of each track was circulated at all levels thus ensuring
management support

the traditional approach
• Better team morale – Team feeling agile is the way to go !
• Increased appreciation between business, developer &
test teams for their respective work

In Conclusion….
• Start with simple practices that are easy to adopt
• Implement a piece meal approach
• Advanced practices like extensive Automation, Test Driven
Development can come in later
• Allow the team time to adapt to the agile way of working
………..And you will realize instead of being
