Process Decision Program Chart (PDPC)

Introduction: PDPC

A Process Decision Program Chart (PDPC) is a planning tool used to identify possible risks in a plan and prepare countermeasures. It helps teams think ahead, anticipate problems, and ensure plans are realistic and resilient.

Background

The PDPC is one of the Seven Management and Planning Tools developed in Japan to support structured decision-making and quality improvement. It is often used after a Tree Diagram, adding a deeper layer of risk analysis and preventive thinking.

Key Elements / Features

• Main plan – The overall goal or project is written at the top.
• Breakdown of steps – Sub-goals and tasks are mapped out.
• Risk identification – Possible problems for each step are listed.
• Countermeasures – Actions to prevent or reduce the impact of those problems are defined.
• Visual format – The chart resembles a branching tree with added “what if” scenarios.

Applications / Examples

• Project planning – Anticipating risks in large-scale projects such as product launches.
• Process improvement – Identifying obstacles in Lean initiatives before implementation.
• Event planning – Preparing responses for logistical or resource problems.
• Healthcare – Analysing possible issues in patient pathways and designing preventive actions.

For example, in a product launch plan, a PDPC may reveal risks such as supplier delays or IT failures. Countermeasures like securing backup suppliers or testing systems in advance can then be built into the plan.

Relevance / Impact

The PDPC improves reliability and reduces surprises during implementation. By preparing for risks, teams can respond faster and increase the chance of project success. It supports proactive thinking and builds confidence in complex plans.
