Measure on Underlying Items |
Specifies that you want to measure the context by an index of perspectives. Only perspectives associated with this context are displayed in the Perspectives list.
Then specify a calculation method and select the perspectives whose scores will be used to define the performance of the context.
Enter sequential numbers in the Index Values from low (red) to high (green). For example, 1, 2, 3, 4, 5 when using five status indicators and 2, 3, 4 when using three status indicators. The number of status indicators depends on the setting.
When measuring by perspectives, an association occurs as follows: the status color of each perspective is matched to the same color in the Index Values list. Based on the color match, each perspective is assigned that index value. The index values are then used in the specified calculation. The resulting value from the calculation is matched to the appropriate color in the Index Values list, and that color is used for the context's status indicator.
The calculation methods are as follows:
-
Least Value sets the context's status color by the status color of the perspective with the smallest index value. Use this when a context's performance is only as good as its lowest performing perspective. The context indicates poor performance if any one of its perspectives has poor performance.
-
Greatest Value sets the context's status color by the status color of the perspective with the greatest index value. Use this when a context's performance is only as good as its greatest performing perspective.
-
Arithmetic Average sets the context's status color by averaging the Index Values of the perspectives. The resulting number is matched to the respective index color to determine the context's status indicator color. If the result has a fraction from .0 to .49, the number is rounded down. If the result has a fraction from .5 to .99, the number is rounded up. Use this when a context's performance is based on an averaging of all its perspectives.
-
Weighted Average sets the context's status color by a weighted average of the Index Values of the perspectives. The index values of the perspectives are averaged along with weights applied to each perspective. The resulting number is matched to the respective index color to determine the context's status indicator color. If the result has a fraction from .0 to .49, the number is rounded down. If the result has a fraction from .5 to .99, the number is rounded up. Use this when a context's performance is based on an averaging of all its perspectives, but some perspectives are more important or less important than others.
If Weighted Average is the calculation method, then the Weights column appears so you can add, change, or remove the individual weights applied to each perspective during the calculation. Weights define the relative importance of the objectives during the Weighted Average calculation method. The weighted average is calculated as: ((perspective_index_value x weight) + (perspective_index_value x weight) + ... ) / (weight + weight + ...)
