Since 1978, AT&T has been developing the call processing simulator (CA
PS) to design and evaluate inbound call centers. The current version o
f CAPS is a user-friendly PC-based system employing a discrete event s
imulation model with animation and queuing models of both the telecomm
unications network and AT&T's business customer's call center environm
ent. Using CAPS, AT&T can model a network of call centers utilizing ad
vanced 800 network features before its customers make capital investme
nts to start or change their call centers. In 1992, AT&T completed abo
ut 2,000 CAPS studies for its business customers, helping it increase,
protect, and regain more than one billion dollars in an eight billion
dollar 800-network market. While this is impressive alone, the CAPS t
ool is also the turnkey for more than $750 million in annual profit fo
r AT&T's business customers who received CAPS studies.
