Every size business needs to have networks that run reliably and quickly. NetQoS (for "Quality of Service") makes software that monitors networks for more than 250 corporate clients, including American Express, Chevron, Cisco Systems, and Halliburton. By preventing network crashes, NetQoS helps clients cut costs. The company, based in Austin, Texas was #43 On the Inc. 500 in 2005. Since then, NetQoS has doubled revenues to $20 million. Inc. Technology spoke with co-founders Joel Trammell, CEO, about how network performance can impact businesses' success.

Inc. Technology: Describe your company's specialty.

Joel Trammell: We help companies optimize the performance of their networks. If it's taking 10 seconds to get a program to come up on line, or five seconds for the network to respond to a command, our software can help you make it one second. Which for a large corporation can be a huge savings.

Inc. Technology: What do business leaders need to know about monitoring their IT networks?

Trammell: Network performance issues have increased dramatically in recent years, and the biggest influence driving this trend is the now common user expectation of a ubiquitous and instantaneous network. Some of the challenges of making this happen are data center consolidation, increased numbers of remote users, the rise of voice and video traffic, legacy applications and more complex applications including service-oriented architectures. The organizations coping most successfully with these challenges are the ones using network performance management tools to optimize their network infrastructure.

Inc. Technology: Does the customer notice anything?

Trammell: Studies have shown that as response times for websites increase, customers are more likely to abandon their shopping carts and not complete a transaction if network performance is under par.

Inc. Technology: How are employees impacted?

Trammell: If employees use an accounting application with a five second response time across the network, and then the performance improves to one second, they're thrilled. If, however, it slows to 10 seconds, employees are going to be upset. It could impact motivation.
