Have you ever had the need to send a survey to different groups of recipients, say Sales and Operations? And have you wanted to analyze and compare those results group by group as well as overall? This is where segments come in.
Survey segments allow you to set up a different response collection "bucket" for your survey in order to tailor your survey to different groups of respondents and allow better reporting of results. For example, let's say that you are conducting a survey in your organization to determine perception about the capabilities and responsiveness of your IT group. You would like to see how IT folks would answer it as well as other departments, such as Marketing & Sales, Client Service, etc. The set of questions you would ask are exactly the same but the responses will need to be reported on by department as well as in aggregate. This is where segments come into play.
By default, each survey comes with a primary segment. Primary segment has a unique link (same as the survey) that you can distribute to respondents to provide feedback. You can create additional segments for your survey, and each of those segments will have its own unique link. Once you distribute the links to your new segments to your respondents, all collected responses will be automatically connected to the specific segment in the provided link. That allows you to group and report results (counts, averages, comments) for each individual segment in the survey as well as across entire survey.
In addition, you can customize each segment by specifying start & end dates for when the segment is active, limit the number of responses per segment (and survey overall), password protect the segment and more. You can distribute the segment link or let people know about it in a number of ways - by email, on Facebook, or on your website.
If we return to our example above, to achieve what we need we would create a segment called Marketing. We would then customize the options, such as set response limit to a particular number, force the end date to ensure all responses are submitted on time, and maybe set a password. We would then send the link to the Marketing group to fill it out. Then, we would create another segment called Client Service and configure appropriate options and distribute the link when done. We would continue doing this until all response segments requirements are satisfied. When all desired responses are in, we can search and filter results either across the entire survey or for each individual segment.
