As the importance of the online channel has grown, so have the challenges for managing complex Web applications and related e-business infrastructure. At the same time, enterprises must continually optimize the online experience as perceived by end users. Keynote's Total Performance Management (TPM) symposium is designed to educate attendees on these challenges and will describe a best practices approach for addressing them rationally and in an extremely cost-effective fashion.

Geoffrey J. Penney, EVP and CIO of Charles Schwab Corp. (NYSE "SCH"), will deliver the opening presentation entitled, "The Performance Imperative," beginning at 8:45 a.m. Mr. Penney manages Schwab Technology, including technology operations, telecommunications and services, as well as client and business applications development and support.

A variety of sessions and topics will be included at Keynote's TPM Symposium including: Application Performance Management: Challenges and Benefits; Best Practices for Web Application Deployment; The Secrets of SLA Management; Web Application Tuning for Peak Performance and Best Practices for Triaging, Diagnosing and Fixing Performance Problems.

At the symposium, Ed Rudolph, vice president Americas software sales for HP (NYSE "HPQ"), will discuss the HP OpenView adaptive enterprise initiative and how the HP Web Application Management suite combined with Keynote Application Perspective allows enterprises to adapt their IT infrastructure to the business goals of the end user by diagnosing and triaging problems inside and outside the firewall.

HP and Keynote will present a live fast-paced demonstration of Application Perspective for HP OpenView, a new and unique joint solution targeted at addressing the "performance management challenge."

Peter Piela, vice president of product development for Segue Software (Nasdaq-SCM "SEGU"), and Keynote will detail their joint solution for total e-business lifecycle testing. Additionally, Pfizer and Deloitte executives will appear on panel discussions and HP, Segue and Netli will be part of a mini exhibition fair.

A unique and valuable session has been added to the symposium based on Keynote's recent acquisition of NetRaker, a leader in customer experience management solutions. Douglas van Duyne, the co-founder and CEO of NetRaker, and now Keynote's senior director of customer experience management products and design, will lead the session entitled "Understanding and Improving the Complete Customer Experience." Mr. van Duyne is a well-known expert in Web site design and the co-author of a popular book on the topic entitled "The Design of Sites." Signed copies of Mr. van Duyne's book will be given away at the symposium.

Additional symposium speakers include: Chip Anderson, StockCharts.com; Norman Follett, engineering program manager, HP; Terry Fung, global senior manager of operations, Deloitte; and Usman Rabbani, global business technology, Pfizer.

All TPM Symposium attendees will receive a free 30-day trial of Keynote's new transaction monitoring service, Application Perspective Outside Edition (a $500 value).

Finally, symposium attendees will have the opportunity to receive a complimentary signed copy of a Cisco Press book entitled, "Practical Service Level Management: Delivering High-Quality Web-Based Services," by John McConnell with Eric Siegel, former principal Internet consultant with Keynote and currently a senior analyst with The Burton Group. Mr. Siegel is presenting the session entitled, "The Secrets of Service Level Agreement (SLA) Management," that highlights the key points from his book that address this topic.

"We have an action-packed agenda that will be of very practical value to any IT executive responsible for managing the performance of their online presence," said Arnold Waldstein, vice president of marketing and business development at Keynote. "Attendees will also receive a first hand live demonstration of Application Perspective for HP OpenView, a brand new and extremely cost effective solution developed by HP and Keynote for quickly detecting, diagnosing and validating performance problems behind the firewall from the end user perspective."
