PROCESS DECISION PROGRAM CHART [PDPC Chart]
A PDPC Chart is a method that graphically displays as many alternatives and contingencies that can be determined in advance to strategies for dealing with them can be determined in advance.
A PCPC CHART IS USED FOR:
- Exploring all of the possible contingencies that could occur in the implementation of any new or untried plan that has risks involved.
- Implementing a plan that is complex and the consequences of failure are serious.
- Implementing a plan in which there is generally a time constraint for implementing a plan so that insufficient time is available to deal with contingent problems as they occur.
STEPS IN CONSTRUCTING A PCPD CHART:
- Select a team that is familiar with the process and possible contingencies. Typically, this will be a group that has been close to the effort or a similar effort.
- Determine the flow of the activities of the plan and place them on a flow chart or sequence.
- Construct a tree diagram, placing prerequisite activities in a time sequence. This can be done either a horizontal or vertical format.
- At each step, ask "what could go wrong here?" and place that contingency on the chart.
- Determine plausible explanations/solutions to each problem identified above and place the solution on the chart.
