PDPC

"Process Decision Program Chart (PDPC) is a technique designed to help prepare contingency plans. The emphasis of the PDPC is to identify the consequential impact of failure on activity plans, and create appropriate contingency plans to limit risks. Process diagrams and planning tree diagrams are extended by a couple of levels when the PDPC is applied to the bottom level tasks on those diagrams. ...
From the bottom level of some activity box, the PDPC adds levels for:
(1) identifying what can go wrong (failure mode or risks);
(2) consequences of that failure (effect or consequence);
(3) possible countermeasures (risk mitigation action plan)." [Process decision program chart. Wikipedia]
The process decision program chart (PDPC) example "Personal activity" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the solution "Seven Management and Planning Tools" from the Management area of ConceptDraw Solution Park.

"Process Decision Program Chart (PDPC).
A useful way of planning is to break down tasks into a hierarchy, using a tree diagram. The PDPC extends the tree diagram a couple of levels to identify risks and countermeasures for the bottom level tasks. Different shaped boxes are used to highlight risks and identify possible countermeasures (often shown as 'clouds' to indicate their uncertain nature). The PDPC is similar to the Failure Modes and Effects Analysis (FMEA) in that both identify risks, consequences of failure, and contingency actions; the FMEA also rates relative risk levels for each potential failure point." [Seven Management and Planning Tools. Wikipedia]
The Risk diagram (process decision program chart, PDPC) determines the risks when corrective action is not performed correctly. Also, it helps develop descriptions for preventive actions at the level of execution.
The Risk diagram (PDPC) template for the ConceptDraw PRO diagramming and vector drawing software is included in the solution "Seven Management and Planning Tools" from the Management area of ConceptDraw Solution Park.
