Process decision program chart


Process Decision Program Chart 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.

Methodology

From the bottom level of some activity box, the PDPC adds levels for:
  1. identifying what can go wrong
  2. consequences of that failure
  3. possible countermeasures
