Contingencies and Triggers
Contingencies are potential risk response actions that will only be implemented if some triggering event or condition has shown that the risk probability has gone from unlikely to likely.
When to use
When the risk analysis (qualitative and quantitative) has been completed, risks that are high impact but low probability often are addressed with contingencies and triggers.
The triggering condition is tracked by the project team. If the trigger occurs, the risk mitigation response is implemented.
In addition, when a rebaseline occurs or at the beginning of each phase or stage, the risks are again considered for contingencies and triggers.
When a contingency is implemented, other risks are checked to determine if the probability of those are increased or decreased by implementing the contingency.
Instructions
This risk response is a two step response. The first step is to accept the risk. This is usually because the risk is unlikely. At this point the project plan normally remains unchanged.
However, an alternate project plan is developed (at least the first few steps) for the unlikely condition when that risk does occur. This alternate plan normally has some detrimental attributes as compared to the normal plan (it costs more, it takes longer). If the alternate plan was better than the normal plan, the project team should switch to the alternate plan immediately.
In addition to developing an alternate plan, a project condition should be selected to act as a trigger indicator. If the trigger condition occurs, it indicates that the risk has changed from unlikely to likely (or present).
When the trigger indicates that the risk in now likely, it is time for the second step; the project plan is changed to the alternate plan that includes a risk response for the risk condition.

Triggers
Triggers are monitored by the project leader and Core Team. Effective triggers have these characteristics:
- Appropriate for the type of risk
- Timely to allow implementation of alternate plan
- Discrete for a clear indication of the triggering event, no ambiguity
- Documented so that the team knows what they should be tracking
