What information is displayed in Where do we have technology risk?

A nested matrix shows the business capability model with information about the amount of time that components will support the business capabilities. A component supports a business capability via the applications that use the component in order to support the business capability. Component support is provided during the lifecycle phases Manufacturer Support and Manufacturer Extended Support, which indicate that the vendor of component still provide support for the component.

Here's how to interpret the information:

Each business capability is represented by a nested box in the matrix.
Per default, the top 2 levels of business capabilities in the business capability hierarchy are displayed.
Each second-level business capability displays matrix cells indicating the amount of time that components will support the business capabilities on a specified date. Each matrix cell also shows the number of components available to the business capabilities. The number is an aggregation of the components used by all applications that provide support to the second-level business capability and its subordinate business capabilities.
Second-level business capabilities are colored based on how many components do not have vendor support on the specified date. The most critical business capabilities are shades of red. The less critical business capabilities are shades of yellow.
The matrix cells are colored based on the remaining time that the component is supported by the vendor. The amount of time is based on the end date of the component's lifecycle phase Manufacturer Extended Support. Matrix cells representing components that no longer have support are red and components with only 6 months of support are pink. If component lifecycle phases are not specified, the matrix cell is grey.
