Number of candidates to be trained by Amplify, for 2010-11: 450+ candidates
Amplify’s contribution in this training: With over a decade of experience on smartphone
platforms, wireless and mobile technologies - Prashant Hinduja, along with his team of experts in
domain of embedded, Linux and Java, designed a custom program to suit the specific needs of
SISO, so that after the training, the candidates not only have exposure to internals of Android, but
also have great amount of hands-on skills developed with assignments, practice tests, and
homework projects, so that they can handle challenging and innovative tasks for their project,
more efficiently and swiftly, on their own.
Training delivery methodology: Since the number of candidates in SISO, to be induced and trained
on Android is quite large, the delivery methodology proposed along with Project Managers and
Training Practice Heads, was to have staggered batch-wise training execution. Each batch’s
training is spread over 2 to 3 weeks, with enough breathing time for candidates to reflect on
instructor contact sessions, in-class exercises, perform practice assignments and offline group
projects, so that the concepts and practical usage is absorbed in all candidates, so that they can
also clarify all queries with the trainer, mainly during the training period.
Training evaluation mechanism: There are regular evaluations of every candidate by the trainer,
through personal interactions during the sessions and breaks, through regular (in-between program
and end program) tests and practice/homework assignments assessment. At the end, the trainer
will provide to the requestor (client co-ordinator from the Training department), a report sheet
with test scores, assignment scores, and trainer’s remarks and recommendations for every
candidate, so that it is helpful for the Project manager to accordingly plan and allocate their
resources from the post-training batch.
No of Batches: 10
