Process Decision Program Charts (PDPC) have 2 main uses: documents steps to completing a process and impact analysis. PDPC does this through a systematic exploration of a process and what could go wrong. This is helpful project management tool in the Improve phase of DMAIC before implementing your plan but I find it helpful in the analyze phase after process mapping to check my understanding of current state.
Process Decision Program Charts are considered part of the 7 management tools (7M)
When Would You Create Process Decision Program Charts (PDPC)?
Not every six sigma tool has to be used on every project. After all, it takes time and effort to implement these things. PDPC is best used when:
- You’re about to enact a new process.
- You’re delivering a large and complex project.
- The cost of the process failing is high.
How to Create a Process Decision Program Chart?
1) First you start with a tree diagram of your process.
Put your objectives on the first level, main activities on the second level, and the tasks at the 3rd level.
2) Then you brainstorm issues that could occur while performing those tasks.
Step 3: Cross off issues that are unlikely to happen.
Step 4: Identify countermeasures for the likeliest issues
