The 8D method (Eight Disciplines Problem Solving) is a structured approach to problem solving that is used particularly in quality assurance and production management. Developed by the automotive industry, this method has already helped many organizations to identify problems and find sustainable solutions thanks to its systematic approach. In this article, we take a detailed look at the 8D method and the parallels to classic project management methods.
The 8D method comprises eight steps, which are referred to as disciplines. Each step aims to thoroughly analyze the problem, identify the causes and implement measures to resolve it. Here are the eight disciplines:

D1: Form a team
An interdisciplinary team is formed to utilize the different perspectives, expertise and experience. This is crucial for a comprehensive problem analysis.
D2: Describe the problem
A clear and precise description of the problem is created. Important information such as what, where, when and how often is taken into account.
D3: Take immediate action
Temporary measures are being implemented to minimize the impact of the problem while the causes are further investigated.
D4: Root cause analysis
A thorough analysis of the underlying causes is carried out here. Methods such as the 5-Why analysis or fishbone diagrams (Ishikawa diagram, also known as the 7M method) are often used.

D5: Identify corrective actions
Once the causes have been identified, suitable corrective measures are decided and planned.
D6: Implement corrective measures
The planned corrective measures are put into practice.
D7: Check the effectiveness of corrective actions
The measures taken are evaluated to ensure that they have solved the problem permanently.
D8: Completion and knowledge assurance
The process is completed and all findings are documented and communicated to relevant stakeholders. This helps to avoid similar problems in the future. Appreciation of the team’s performance(!) should also be included.

Parallels to classic project management methods
Although the 8D method was designed specifically for solving problems in quality control, there are several parallels to classic project management methods such as IPMA, PRINCE2, PMI or agile approaches:
1. Structured approach
Similar to many project management methods, the 8D method follows a clear, defined process. Each step builds on the previous one, which ensures a structured approach – a common feature of many project approaches.
2. Teamwork
Teamwork is crucial in both approaches. Interdisciplinary collaboration promotes the development and exchange of ideas and solutions.
3. Documentation and communication
Documentation plays a central role in the 8D method in order to track the problem-solving process and record findings. Comprehensive documentation is also essential in project management in order to track progress and inform stakeholders.
4. Risk management
Risk management is an important aspect of both the 8D method and project management. In the 8D method, risks are analyzed and measures are taken to minimize them. In project management, similar techniques are used to identify and mitigate potential risks.
5. Evaluation and feedback
The 8D method includes an evaluation phase to check the effectiveness of the measures, which parallels the continuous improvement in many project management approaches. Feedback loops are particularly pronounced in agile methods in order to be able to react quickly to changes.

This table now provides a comprehensive overview of the similarities and differences between the 8D method, classic project management methods and the PDCA circle.
Aspect | 8D method | Classic project management methods | PDCA circle |
---|---|---|---|
Objective | Systematic problem solving and quality improvement | Planning, implementation and completion of projects | Continuous improvement of processes |
Structure | Eight structured steps (D1 to D8) | Defined phases (initiation, planning, execution, completion) | Four phases (Plan, Do, Check, Act) |
teamwork | Interdisciplinary team for problem solving | Project teams with different roles and expertise | Teamwork promotes participation and idea development |
Documentation | Comprehensive documentation of all steps and findings | Detailed project documentation (reports, minutes) | Documentation of changes and results |
Risk management | Analysis of risks in root cause analysis and corrective measures | Risk identification and assessment are key components | Identification of risks during the planning phase |
Evaluation | Verification of the effectiveness of the corrective measures (D7) | Evaluation of project progress and results | Checking the results after implementation |
Feedback loops | Constant adaptation based on findings | Agile methods (e.g. Scrum) use iterative feedback loops | Regular review and adjustment of the process |
Area of application | Frequently used in quality assurance, manufacturing and industry | Diverse, including construction, IT, research and development | Universally applicable in various industries |
Duration | Fast problem solving, usually at short notice | Project timeframe can vary from short to long term | Often a continuous, long-term process |
Main focus | Identification and elimination of problems | Achievement of project goals and milestones | Continuous improvement of products and processes |
Conclusion
The 8D method is an effective problem-solving tool that is characterized by a structured, team-oriented and documented approach. Its parallels to classic project management methods and the PDCA cycle underline the universal principles of teamwork, communication and continuous improvement. In a world increasingly focused on quality and efficiency, the combination of these methods is proving to be extremely valuable for organizations in various industries.
