Better visibility supports key future-proofing initiatives
Unbiased insight reduced troubleshooting times from weeks to hours
Real-time analytics help IT proactively support end-user digital experience
DDI needs to quickly evaluate and resolve performance problems before they impact customer experience
Founded in 1970, Development Dimensions International (DDI) now operates 42 offices in 26 countries, providing the world's top organizations — including half of the Fortune 500 — with leadership assessment and development training. Their web-based testing and assessment applications are used weekly in more than 90 countries, helping DDI clients make upwards of 3,200 hiring decisions every hour. Since the company's founding, it has successfully screened more than 20 million candidates.
"When the world's leading companies rely on your applications to inform their hiring and other personnel decisions, performance problems or latency materially impact the pace and efficiency of business," says Jake Whitlock, Network Engineer for DDI. For Jake and the rest of the IT team at DDI, keeping the assessment and testing applications up and running and ensuring connectivity for their globally distributed operations are mission critical.
While application performance and availability are at the core of the IT team's mission, it's not the only consideration. According to the Global Corporate Training Market 2015-2019 report from Sandler Research, the corporate training market is expected to grow at a CAGR of 8.77% from 2014-2019. That growth means those applications need to scale up.
"It's not enough for IT to support the business as it exists today. Everything that we do — from the technologies we purchase to the applications and features we design — must be done in the context of where our business will be in three to five years," says Jake. "We have to anticipate the scale, complexity, and demand of the future. If we succeed in that, our customers — and DDI — win."
ExtraHop gives us the visibility we need to be smarter, faster, and more data-driven about our current operations, and keeps us focused on the future.

IT analysis from ExtraHop gives accurate and timely visibility from the network all the way through end-user experience
With dual mandates around end-user experience and future-proofing, the IT organization at DDI needed a way to gain accurate and timely insight that would get them to root cause and resolution faster. They found it in ExtraHop.
Identifying a Leader
When it came to IT monitoring tools, the IT team at DDI was used to solutions that only offered visibility into a narrow slice of the infrastructure. That meant trying to manually correlate log data with the views they were getting from point solutions.
"With ExtraHop, we very quickly realized that we could see much more than just HTTP," says Jake. "For the first time, we could visualize both the end-user experience and corresponding performance issues across the infrastructure in a single UI. It brought everything into focus."
Slow Connection to China
The first challenge that Jake and his team threw at ExtraHop was an application latency issue that customers were experiencing at their assessment centers in China. The ExtraHop account team helped them spin up a virtual appliance at a remote site in China. They were quickly able to dig into user sessions to understand both end-user experience and the back-end performance impacting it.
