Concept: Score Aggregation

Concept: Score Aggregation

The score aggregation algorithm only includes the most recent scores for each employee in overall results, by defining a visibility window. The question sampling algorithm, in turn, reduces the number of questions per round. Every survey round asks all active and enabled questions, but not to all employees at the same time.
Score aggregation provides various benefits over a traditional annual survey.
  • Enables sampling of questions from survey to survey, while still retaining an accurate picture of all drivers across the company.
  • Enables inclusion of results from different parts of the company surveying at different frequencies.
  • Ensures that only recent answers for each employee contribute to overall results.
  • Responses from former employees only contribute for a short amount of time.
The base date for driver calculations is the end of a survey round. The current score for a company or segment is from the end of the last round.
Score aggregation operates on a per question set basis. This means that the scores and dashboards of question sets only recalculate when you include the question set in a survey round.

Score Aggregation

Score aggregation happens during every single survey round, by referencing all responses against the visibility window you selected. If you stop running surveys, the dashboards don't update even as the real-life visibility window moves forward.
  1. The algorithm excludes any answers from survey rounds that fall outside of the
    Aggregation period
     window.
  2. Answers from former employees no longer contribute to the current score if the separation or deletion date falls outside of the
    Inclusion of former employees
     window.
  3. Only the most recent answer from each employee contributes to the current score of each question that they answered.
  4. The algorithm calculates the average score for each driver and subdriver, for each employee.
  5. The algorithm calculates the overall average score for each driver and subdriver.
The visibility windows amount to an exact number of weeks, rather than specific dates.
  • 1 month equals to 4 weeks.
  • 3 months equal to 12 weeks.
  • 6 months equal to 26 weeks.
  • 1 year equals to 52 weeks.
