1. 5 Whys: This method involves asking "why" multiple times to get to the root cause of a problem. By asking why five times, you can uncover deeper issues that may be contributing to the problem.
2. Fishbone diagram (Ishikawa diagram): This method involves creating a visual representation of all possible causes of a problem, organized into categories such as people, process, equipment, and environment. This can help identify the root cause by analyzing the relationships between different factors.
3. Fault tree analysis: This method involves creating a diagram that shows the logical relationships between different events and their potential causes. By tracing back from the problem to its root causes, you can identify the key factors contributing to the issue.
4. Pareto analysis: This method involves identifying the most common causes of a problem by analyzing data and determining which factors have the biggest impact. By focusing on the most significant causes, you can address the root cause more effectively.
5. Root cause mapping: This method involves creating a visual map of the problem and its causes, using tools such as flowcharts or process maps. By mapping out the relationships between different factors, you can identify the root cause and develop a plan to address it.

Common Methods for Conducting Root Cause Analysis
1. Ishikawa (Fishbone) Diagram:
- Identifies potential causes contributing to a problem by categorizing them into major branches (e.g., people, processes, materials).
- Facilitates brainstorming and visualization of cause-and-effect relationships.
2. 5 Whys:
- Repeatedly asks "Why?" to drill down through layers of causation.
- Helps uncover underlying root causes by identifying the reasons for each contributing factor.
3. Failure Modes and Effects Analysis (FMEA):
- Systematically evaluates potential failures, their effects, and the severity and probability of their occurrence.
- Identifies potential failure modes and develops mitigation strategies.
4. Change Analysis:
- Examines changes that occurred before a problem возникла.
- Identifies changes that may have contributed to the problem and suggests corrective actions to prevent recurrence.
5. Statistical Process Control (SPC):
- Uses statistical techniques to identify variations in processes and identify potential root causes.
- Charts data to monitor trends and detect deviations that indicate underlying problems.
6. Root Cause Analysis Trees:
- Creates a hierarchical representation of potential causes and their relationships.
- Facilitates logical reasoning and identification of contributing factors at different levels.
7. Fault Tree Analysis (FTA):
- Develops a logic diagram that shows how multiple component failures can lead to a system failure.
- Identifies critical failure points and develops strategies to prevent or mitigate their occurrence.
8. Event and Causal Factor Analysis (ECFA):
- Reconstructs events leading up to a problem by identifying the sequence of causes and effects.
- Uses interviews, documentation, and other evidence to create a timeline of events.
9. Systemic Root Cause Analysis (SRCA):
- Examines problems from a holistic perspective, considering the interconnectedness of systems and processes.
- Identifies systemic weaknesses that contribute to recurring problems.
10. Management Oversight and Risk Tree (MORT):
- Evaluates the effectiveness of management systems and identifies areas of risk that could lead to problems.
- Facilitates the identification of root causes related to organizational culture, leadership, and decision-making.
