Rather than surveying all employees (called a census survey), try fielding your next survey with a representative sample: a small group of employees that reflects your organization.

The smart folks at the Pew Research Center published this helpful video that explains how random sampling works.

While it’s much easier to email a survey to all employees, here are a few reasons to consider a sample:

• If surveys are popular in your organization, using a sample helps you manage and reduce the number of surveys each employee receives.
• You’ll reduce the burden on the organization; that is, your survey will require less time from employees overall—an important thought if you need to field the survey during a busy time.
• If you survey often about communication, your survey will feel more unique and encourage participation.

Ask yourself these three questions, when you’re trying to decide if a sample methodology is right for your situation.
