The collaboration initiative has helped Infosys upgrade video, audio and web conferencing infrastructure and it has also helped it introduce high definition audio and video. "With this, the average number of video conferences have increased from 300 to 1,000 per month. This has reduced travel costs," says Krishna.

But each initiative came with its set of challenges. For ISO 20 K, there was a need to benchmark the practices and performance and there was no structure in place to track service improvements. Involving business reps and other stakeholders in rolling out key changes helped the company combat these challenges. User awareness was very important when it came to deploying green IT initiatives. A series of mailers were sent to the employees to alert them about adopting green practices. The collaboration platform was a multi-team, multi-vendor project posing pre-implementation integration challenges. The solution also had to be secure and user-friendly. But, the team took care of these requirements and a unique tightly integrated solution was built.
