Which of the following is a method for problem solving listed in the material?

• A. OSHA's problem-solving techniques
• B. Root Cause Analysis
• C. Six Sigma
• D. PDCA cycle

Answer: (A)

The fundamental idea here is identifying which problem-solving method the material specifically names for guiding investigations. The material presents OSHA's problem-solving techniques as the designated method to use. These techniques provide a clear, regulatory-aligned process—define the problem, gather facts, generate and evaluate solutions, implement corrective actions, and verify effectiveness. Because the text explicitly lists OSHA's techniques as the method to follow, this is the best choice in that material's context. While Root Cause Analysis, the PDCA cycle, and Six Sigma are well-known problem-solving approaches, they aren’t the method named in this material, even though they can be relevant in other settings.
