    What type of data is: Time in minutes to complete Triage?

    • A.

      Obscure

    • B.

      Discrete

    • C.

      Continuous

    • D.

      Discretionary

    • E.

      Primary

    Correct Answer
    C. Continuous
    Explanation
    Continuous data refers to data that can take on any value within a certain range. In this case, the time in minutes to complete Triage can vary continuously, as it can take on any value within a certain range (e.g. 1.5 minutes, 2.3 minutes, etc.). This is in contrast to discrete data, which can only take on specific values (e.g. number of patients seen in a day). Therefore, the correct answer is continuous.

    Which is NOT true for a Charter

    • A.

      Clarifies what is expected of the project team

    • B.

      Manages the scope the project

    • C.

      Keeps the team aligned with organizational priorities

    • D.

      Clearly states the root cause

    Correct Answer
    D. Clearly states the root cause
    Explanation
    A charter is a document that outlines the purpose, objectives, and scope of a project. It clarifies what is expected of the project team, manages the scope of the project, and keeps the team aligned with organizational priorities. However, stating the root cause is not a characteristic of a charter. The root cause analysis is a separate process that is performed to identify the underlying cause of a problem or issue. Therefore, the statement "Clearly states the root cause" is not true for a charter.

    Correct Answer
    C. Help you understand your work as a process
    Explanation
    A SIPOC (Suppliers, Inputs, Process, Outputs, Customers) is primarily used to help you understand your work as a process. It provides a high-level overview of a process by identifying the suppliers, inputs, process steps, outputs, and customers involved. By mapping out these elements, a SIPOC helps to visualize the flow of work and understand how each component contributes to the overall process. This understanding is crucial for identifying areas of improvement, waste, and inefficiencies in the process. It also helps in creating a detailed flowchart of the process.

    Rate this question:

  • 16. 

    Special cause variation is always present to some degree in any process.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Special cause variation refers to variations in a process that are caused by specific factors that are not part of the normal process. These factors can be identified and eliminated to improve the process. However, special cause variation is not always present in any process. In fact, the goal of process improvement is to reduce special cause variation as much as possible, leaving only common cause variation, which is inherent to the process and cannot be eliminated. Therefore, the correct answer is False.

    Driver diagrams help you select which processes influence a specific area

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Driver diagrams are a visual tool used to identify and understand the key drivers or processes that influence a specific area or outcome. They help to map out the cause-and-effect relationships between different factors and determine which processes have the most significant impact. By using driver diagrams, organizations can prioritize and focus their efforts on the most influential processes to achieve their desired outcomes. Therefore, the given statement that driver diagrams help in selecting which processes influence a specific area is true.
