Look at Q3, not only did we react by revising our guidance, we were able to meet those numbers.

What's your advice to other CEOs?

Those who are focused, who are able to bring their products and services to these markets, will continue to do well and increasingly, I think they will even see growth. The key is to make sure that you run your business as efficiently as possible, that you have tight control over your business operations and you have metrics to measure how your business is performing so that you can react fast. All this will require investments in systems and technology.

For example, on the last day of every month, at 3 pm, I get Infosys' trial profit and loss position. Within two week of the quarter end, we announce audited results. That wouldn't be possible without good systems. Or take our decision to cut travel by 20 percent. It was done immediately. I could put budgetary controls into the system to cut budgets and if someone exceeded that budget, travel would require exception approval. It was very simple for us to do.

Without systems like Unified Communications (UC), you can't do that.
