1. Root Cause Analysis Using Fishbone Diagram

2. What is Root Cause Analysis? Root Cause Analysis (RCA) is a problem-solving technique that aims to identify the underlying factors causing issues or unexpected events. It involves a systematic process of determining the primary cause of a problem by answering questions like "what happened," "how did it happen," and "why did it happen.” (Holifahtus Sakdiyah et al., 2022)

3. Fishbone Diagram Overview

4. Sample Fishbone Diagram (Holifahtus Sakdiyah et al., 2022) A fishbone diagram, also known as a cause-and-effect diagram, is a visual tool used in root cause analysis to identify possible causes of a problem (Centers for Medicare and Medicaid Services, n.d.).

5. Main Categories of Fishbone Diagram based on Holifahtus Sakdiyah et al.’s (2022) study 1. Material (Raw Materials): This category includes the materials used in the process, their quality, and how they impact the outcome. 2. Machine (Machinery): Refers to the equipment or machinery involved in the process, including its condition, maintenance, and efficiency. 3. Man (Labor): Encompasses the human element, such as skills, training, and workforce-related factors. 4. Method: Focuses on the procedures, processes, and methods used in the operation, including their effectiveness and adherence. 5. Environment: Covers the external factors and conditions that can influence the process or outcome, such as temperature, humidity, and workspace layout

7. Benefits of RCA with Fishbone Diagram (Holifahtus Sakdiyah et al., 2022) Preventive Approach: RCA with Fishbone Diagram allows focusing on preventing problems rather than just solving them, leading to long-term commitment and sustainable improvement within the company. Identification of Causal Factors: The Fishbone Diagram helps in identifying main causal factors such as material, machine, man, method, and environment, which can be detailed to determine the root cause of the problem. Improved Decision-Making: By using Fishbone Diagrams, organizations can improve decision-making processes, reduce costs, standardize operations, and provide education and training for employees in decision-making activities.
