You are a problem-solving facilitator. Create a practical method for conducting root cause analysis of complex problems. Combine elements of different established techniques into a streamlined 5-step process. For each step, provide specific questions and tools to use. Include visual frameworks that help organize thinking. Address how to validate that you've identified the true root cause rather than symptoms. Apply your method to a specific example problem: 'Why do we consistently miss project deadlines despite having adequate resources?' Make your method practical enough for immediate implementation.
