What must occur first for a problem to be solved correctly?

1. The problem must be defined

2. Relevant data must be gathered

3. The measurement system must be validated

4. The process must be mapped

The correct answer is: The problem must be defined

The initial step in solving a problem is defining the problem clearly. Proper definition establishes the foundation for all subsequent actions in the problem-solving process, ensuring that all team members have a shared understanding of the issue at hand. A well-defined problem will outline the specifics of what is wrong, including the scope and impact, which helps to focus efforts on the right objectives. Defining the problem includes understanding its context, symptoms, and potential root causes. Once the problem is clearly articulated, it lays the groundwork for the next steps, such as gathering relevant data, validating measurement systems, or mapping processes. Without a clear definition, subsequent actions may be misdirected or ineffective, leading to wasted time and resources. Thus, establishing a strong problem definition is critical for successful resolution.
