Analyzing a business driver map or correlation map

This topic provides information about analyzing a business driver map or correlation map.

To analyze a business driver map or correlation map

  1. Click Analyze.
    A preview of the results can be accessed from the tabs on the left of the map, such as "Correlations", "Slope", and so on.
  2. To permanently store the analysis results, click Save.

On the top right corner of the map you can find information such as:

  • The date and time of the last refresh of the map.
  • How the associations were created.
  • The status of the estimations.

The following table provides additional information about the displayed results.

Text

Description

N/A

If the text "N/A" appears in a cell, it means that the analysis was not able to produce that result. This is usually due to a lack of samples needed to perform the analysis. In this case, change the time filter or time resolution of the analysis and try again.

Correlations

Correlation coefficients are the first results calculated by the analysis function according to the defined associations and using the metrics measured for the specified time range. The correlations are compared with some general thresholds:

  • 0-30% - Low correlation
  • 30-70% - Medium correlation
  • 70-100% - High correlation

Sample size

This value, only available for business driver maps, represents the size of the sample on which the correlations and the other parameters were calculated.

Charts

In the Charts tab of the analysis page, you can view the charts associated with the map.

If you associate a business driver "B1" and a resource "R1" in the business driver map, you will obtain a chart reporting their data. Depending on the chart type, the data of "B1" and "R1" might be represented on a X-Y scatter plot or in a time chart; the important fact is that a chart appears for every association in the map, allowing you to visually analyze that specific association. Once you have filled the business driver map and run the Analyze function, you can select the Charts tab from the analysis main page and click Run now to generate the charts.

Charts are generated clicking Run now in the Charts tab, while the analysis of the map is triggered clicking Analyze in the Business Driver Map (or Correlation Map) tab. This is because you may want to work with an existing value of service demand estimation and avoid re-analyzing the map, to check how this estimation fits new data in the charts. The service demand line can appear in the X-Y scatter plot, allowing you to check an existing estimation of service demand against new data.

Example of a chart obtained from the analysis of a business driver map

Note for advanced users

In a multivariate case, the solution of the business driver map analysis is a service demand surface, not well represented by a X-Y 2D chart. The chart of a multivariate case is the projection of the N-dimensional U/W cloud on a 2-D plan U/W1. As a consequence, the linear regression of the multivariate case in the chart does not fit visually with the service demand line for this dimension; however, the mathematical estimation still remains correct.
