Network Diagramming Software for Design Computer and Network Diagrams

"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.
