Different organizations use different methods of surveying their organization. Common for them all is that a data point will be showing in the trend when a survey has been sent out and performed given that there are enough results to show.
For an organization that does not use pulse surveys, the reports simply present the result at one data point.
For organizations that use pulse surveys, there are smart aggregations and algorithms in place to make sure that the result is working as intended.
When utilizing pulse surveys, the data is aggregated in the reports with the influence of the latest survey and surveys from 11 weeks back.
The purpose of this is to create a complete overview of the result and to quickly be able to see trends and developments but at the same time not make the trends shift in an unstable way that is not correctly reflecting changes in the organization. Please note that due to smart surveys and aggregation, a segment containing for example 10 users can have more than 10 answers for one question. An answer does not equal one user necessarily.
Simply put, our data scientists, engineers, and psychologist have developed a solution where you can focus on the result and not on math.
Combination of the two
Some organizations may perform both pulse and none pulse surveys to the same parts of the organization. In this case, the organization can choose if the none pulse survey should be a part of the data aggregation or not.
