What is the Process Decision Program Chart (PDPC)?
→ The process decision program chart (PDPC) is used to identify what might go wrong in a plan under development.
→ It is one of the most useful and easy-to-use tools of the New 7 QC Tools (Seven Management and Planning Tool).
→ By using PDPC, we can either eliminate the problems or we can minimize or optimize the problems or we can be ready with a proper action plan if the problem occurs.
→ The Process Decision Program Chart is also known as a contingency planning tool because it is used for developing the contingency plan where a high degree of uncertainty available.
→ This tool ensures the timely completion of the tasks with better Risk Management.
→ Process Decision Program Chart is a very structured approach and follows the below steps.
→ Identifies the objectives then identifies the possible options available then asks what-if questions to uncover potential problem areas then identifies the countermeasures, and finally selecting & implementation the countermeasures.
➨ PDPC Chart is used in various fields as mentioned below
→ Research and analysis
→ Engineering
→ Project management
→ Manufacturing
→ Marketing and sales
→ Servicing and support
→ Change management
When we can use a PDPC chart?
→ When our process has uncertainty.
→ When the plan is large and complex.
→ Implement the contingency plan for high-risk projects.
→ For complete project within the timeline.
→ For new process or project
How to make a PDPC Chart?
→ The PDPC Chart is easily made by 5 Simple Steps that are mentioned below.
- Define Objective to be achieved
- Identify the options Available
- Identified the What if the condition
- Possible Countermeasures
- Selection of Countermeasures
→ Refer to the below-mentioned most common symbols used in the PDPC chart.
Example of PDPC Chart [Process Decision Program Chart]
→ With the help of the above-mentioned structured steps, we will make a PDPC diagram for giving a presentation at the conference.
→ So we will identify the possible risks for that and we will decide the countermeasures for minimizing or eliminating the risks.
Step 1: Define the Objective to be achieved
→ So as per step 1, we need to decide the objective.
→ In this example, it is very clear that we need to give the presentation at the conference.
Step 2: Identify the options Available
→ Now in step 2, we need to identify at a broader level that what are the possible options available.
→ For this, we will refer to the Tree Diagram.
→ We have three different options available at a broader level such as (1) car to reach at venue, (2) use the laptop for presentation, (3) use video projector.
Step 3: Identified the What if the condition
→ Now in step 3, we need to identify the what-if condition for the probable causes of failure for the above-mentioned options.
→ The different causes of failure are mentioned below.
→ (1) car to reach venue - car may breakdown
→ (2) use laptop for presentation - (a) presentation file not found, (b) laptop malfunction
→ (3) use video projector - video projector fails to start
Step 4: Possible Countermeasures
→ Now in step 4, we will find out the possible countermeasures for each potential problem.
→ We will use a brainstorming approach for this.
→ Eliminating or minimizing the risks, countermeasure will help us.
→ Refer to the below-identified countermeasures for the various causes.
→ (1) car may breakdown - (a) hire a car, (b) use a public transport
→ (2) (a) presentation file not found - use a pen drive, (b) laptop malfunction - use organization's PC
→ (3) video projector fails to start - (a) use white-board, (b) use an overhead projector
Step 5: Selection of Countermeasures
→ So after identifying the different countermeasures we need to select the countermeasures and implement the same for eliminating the risks.
→ We need to use various criteria such as cost, time, ease of implementation, effectiveness, etc, during the selection of the countermeasures
→ For your better understanding refer to the below-selected countermeasures.
→ (1) car may breakdown - (a) hire a car - selected, (b) use a public transport - rejected
→ (2) (a) presentation file not found - use a pen drive - selected, (b) laptop malfunction - use organization's PC - rejected
→ (3) video projector fails to start - (a) use white-board - rejected, (b) use an overhead projector - selected
→ We have marked the selected criteria as - O, and rejected criteria as d- X.
Advantages of PDPC Chart:
→ It helps to prepare a contingency plan.
→ PDPC helps us to select the best possible solution for completing the tasks with minimum risks.
→ Very simple tool for using and understanding.
→ Good risk management tool.
