You can administer an employee survey on paper, online, in person, or by telephone. Paper surveys are less popular than they once were because of the advent of online surveys and also because of the labor-intensive process required to scan the survey forms and transcribe any comments.
Telephone and in-person surveys are expensive and labor intensive, but they have a very high response rate. These methods may be best if the population size for the employee survey is very small making it very difficult to reach a representative sample.
Online surveys are very popular because of the ease of deployment and their low cost. Plus, online employee surveys usually enjoy a response rate of 75-80 percent or more.
