A mitigation that successfully changes the value of a decision point may shift the priority of further action to a reduced state. If applying a mitigation reduces the priority to *defer*, the deployer may not need to apply a remediation, if later, it becomes available. Table 3 displays the action priorities for the deployer, which are similar to the supplier case.

In a later section, the different types of impacts are defined and then implemented in the decision trees as examples of how the various impacts affect the priority.
For now, assume the decision points are ordered as: [*Exploitation*](#exploitation); [*Exposure*](#exposure); [*Utility*](#utility); and Well-being and Mission Impact.
For now, assume the decision points are ordered as: [*Exploitation*](#exploitation); [*Exposure*](#exposure); [*Utility*](#utility); and *Human Impact*](#human-impact).
In this order, an [_active_](#exploitation) state of [*Exploitation*](#exploitation) will never result in a *defer* priority.
A [_none_](#exploitation) state of [*Exploitation*](#exploitation) (no evidence of exploitation) will result in either *defer* or *scheduled* priority—unless the state of Well-being and Mission Impact is [_very high_](#combined-situated-safety-and-mission-impact), resulting in an *out-of-cycle* priority.

As opposed to mitigation, applying a remediation finishes an SSVC analysis of a deployed system.
While specific vulnerabilities in specific systems can be remediated, the vulnerability cannot be 'disposed of' or eliminated from future consideration within an IT environment.
