CAMBRIDGE, Mass. -- Certification recognizes AspenTech for delivering top quality support

Aspen Technology, Inc.

AspenTech achieved certification for the third consecutive year after an extensive review by SCP auditors of its Houston, Texas, support center. In order to earn SCP Certification, customer support organizations must meet a stringent set of performance standards that reflect best practices in the industry.

"Achieving SCP Certification for the third year is a testament to the commitment and dedication of our Customer Support and Training group," said Mark Fusco, President and CEO, AspenTech. "The benchmarks used by the SCP are raised every year, so gaining certification demonstrates our ability to continually improve our processes to meet SCP standards, while at the same time satisfying the increasingly complex support needs of our customers."

SCP Certification is an internationally recognized standard created by the Service & Support Professionals Association (SSPA), a consortium of leading technology companies, and Service Strategies Corp.
