A Process Decision Program Chart (PDPC) is a tool for identifying and documenting the steps required to complete a process. It is also useful for anticipating any issues and problems that might surface in the implementation of the process, therefore affording the opportunity to devise countermeasures.
Example: Below is a PDPC for the implementation of statistical process control in the machining area of a plant.
Note that the process statement is at the top level of the chart and the required process steps move from left to right at the next level. Further levels of detail may be required until the final level is reached which indicates countermeasures that might be taken to prevent any delay with the process implementation. The PDPC chart can be a very effective tool for assuring the process is deployed without costly delays and problems. It can also be used in the problem solving process where it allows for the identification of potential process issues that have led to a process failure.
