The road warrior travels from city to city, meets with potential clients and attends conferences and industry events. And their travel requirements don’t seem to be slowing down. According to the Global Business Travel Association, spending on business travel reached record-breaking levels of $1.2 trillion in 2015, and is expected to rise to $1.6 trillion by 2020.

Your road warriors bring your products and services into new markets, diversify clientele and strengthen existing relationships. They’re helping your business grow—now more than ever.

Doing their jobs from the road, however, can prove very difficult without the right productivity tools. So, how do you know if they have what they need?

Start by understanding the common challenges they face. Whether it is hosting meetings, collaborating with colleagues or meeting deadlines, you can make sure they are set up for success.

Here are four productivity fears that often strike business travelers while they’re on the road:

Did I forget to save files from the company server before traveling?

Secure file access shouldn’t be a privilege for in-office employees only. Being able to tap into the company server to access important resources is a basic requirement for most jobs. For employees who are on the move, it’s critical to have such access anywhere, anytime. Whether in a hotel lobby or a cafe, they should be able to connect to Wi-Fi and get their work done. When company documents are secured in the cloud, your employees can continue with business as usual, from virtually anywhere.

Will time away impact day-to-day communication?

For road warriors, productivity is dependent on seamless communication and collaboration with in-office teams. Without face-to-face interaction with colleagues, employees can sometimes feel disconnected—and the ability to connect in multiple ways can make all the difference. Secure video conferencing and messaging tools can bridge the communication gap, allowing business travelers to chat with team members and conduct online meetings on the fly.

Can we successfully collaborate while I’m in another location?

Teamwork is essential to business, whether your employees are on the road or huddled in a conference room. Business leaders must consider the value of technology that lets business travelers create, co-author and share documents in real-time. These abilities enable teams to accomplish tasks and meet deadlines together, from virtually anywhere. Now, with technology for sharing and collaborating remotely, it’s easier than ever.

What happens if I lose my connection to the internet?

Travel often happens during business hours. While on a train or 30,000 miles in the air, your road warrior still needs to email, build sales decks and meet deadlines. But sometimes technology falters and they could lose internet connectivity for minutes or even hours. At times like these, they can rely most on tools that save their work (documents, presentations and even email files) onto a hard-drive while offline and upload upon reconnection. While they’re offline, they can continue to read emails, compose drafts, edit files—and keep making work happen.

The productivity of your traveling employees is only as good as the technology that supports them. As a business leader, you have the power to provide technology that helps them do their jobs while on the road.
