Process Decision Program Chart

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.

  1. Define Objective to be achieved
  2. Identify the options Available
  3. Identified the What if the condition
  4. Possible Countermeasures
  5. 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

Steps in PDPC

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.
