AIMS is a multi-user web-based messaging technology that allows to offer
immediate live help to our customers through online chat. AIMS provide routing of
chats based on service hours and availability of agents. Agents can chat with
multiple customers at the same time and can also communicate with other AIMS
users using One-to-One/Broadcast messaging services. Quick responses allow them
to respond faster to frequent customer queries. The chat window has a user trail
tab to see customer history and track customer activity. Reports module in AIMS
helps to analyze center productivity, agent performance and SLA compliance. One
such report is customer survey report which tracks customer specific responses
and identify the challenging situations.
AIMS has more than 350 centers and 10,000 registered users. Center
Administration component helps to do all maintenance activities like adding new
center, roles, users, queues, surveys & agent categories.
Project Role:
* Design, development and validation of rich GUI components for
administration in AIMS
* Developed Real Time Monitor component to monitor all the live chats
in different centers
* Developed Center Administration component to create centers on the
fly with all messaging configurations, roles, queues, survey and agent
categories
* Programming of JSP pages using DHTML(HTML, CSS & Java script) to
provide User Interface to the application
