The History view compares the current ratings for the categories and their questions
with ratings from the previous three years or four quarters.
Ratings that have declined are highlighted in red and display negative numbers. Ratings
that have improved are highlighted in green with positive numbers. Arrow icons beside the
values in the Diff column indicate the trend of the current survey
against the previous survey.
Point to a category to display a line chart that shows the rating trend for that category.
Click a category to view the Survey Category form containing the survey questions.

To calculate the current ratings, the system averages the ratings from the trailing twelve
month (TTM) period. The Diff column shows the discrepancy between the
current ratings and the previous calendar year's ratings.그림 2. Survey scorecard history - 3 years

Quarterly surveys compare the average rating for each question and category in the current
quarter against the average ratings from the previous four quarters. The
Diff column shows the discrepancy between the current ratings and
the previous quarter's ratings. The column labels count backward, by quarter from the
current quarter. For example, if the current quarter is the 3rd
quarter of 2015, then the previous quarters appear as 2nd [2015],
1st [2015], 4th [2014], and
3rd [2014]. All four of the previous quarters appear, whether or
not there was any data for those quarters.그림 3. Survey scorecard history - 4 quarters
