| J2EE migration and enhancement
of Graphical Local Craft Terminal (GLCT) |

| The client |
| One of the world's
leading Electronics companies |
| |
| Challenge |
 |
Business: Meet
the timelines of the customer as this project
deliverables were linked to releases of a
related product by Wipro's customer |
|
Project management:
|
The customer
had given aggressive deadlines to meet
|
|
Both
migration and enhancement had to be
done in parallel so that the final deliverable
had migration as well as enhancements
done |
|
|
Technical: Customer had
only source code and a few process diagrams
as documentation. Wipro had to gain knowledge
of the existing GLCT by going through the
source code and these few diagrams |
|
Deployment: Customer was
not willing to invest in Infrastructure |
|
| |
| Solution |
|
Business: Through
a mixture of right resource induction into
the project and efficient management of customer/project
the timeline were achieved |
|
Project management:
|
All activities
of each milestone were thoroughly tracked
and informed to customer. Weekly reports
were given to track each milestone |
|
Formed
two core teams with a technical lead
for each one of them. One team look
after the Migration portion and other
team looked after the enhancements |
|
|
Technical: The team analyzed
and documented the compatibility issues of
J2SE versus the older version viz. JDK 1.1.8.
Then source code porting of GLCT from JDK
1.1.8 to J2SE was done. All the deprecated
methods in the old version of JDK 1.1.8 was
replaced with new version APIs of the J2SE
|
|
Deployment: Network element
hardware was not provided by the customer
at offshore for testing. Hence unit testing,
system testing had to be done using a network
element simulator which was developed by Wipro
for the same customer as a part of an earlier
relationship with that customer. Thorough
testing was done at offshore using the simulator
which minimized defects during acceptance
testing phase performed at onsite on the actual
network elements |
