- - - - 🎯Step 4: Prepare for the Interview
        -Preparation is essential; it's a formal meeting, not a casual chat.
        -Limit the interview to one hour or less.
        -Send a list of topics in advance.
        
        🎯Step 5: Conduct the Interview
        -Have a specific plan for the meeting.
        -Start with introductions, the project description, and interview objectives.
        -Practice engaged listening.
        -Give the interviewee time to think.
        -Summarize the session and seek confirmation at the end.
        
        🎯Step 6: Document the Interview
        -Keep note-taking to a minimum during the meeting.
        -Record the information quickly after the interview.
        -Send a memo to the interviewee.
        -The memo should include: date, time, location, purpose, and main points. This provides a written summary for additions or corrections.
        
        🎯 Step 7: Evaluate the Interview
        -Identify the facts gathered and also look for any possible biases.
- - - - 🔗To evaluate scalability, you need information about projected future volume for:
      - 🔗All outputs
      - 🔗All inputs
      - 🔗All processes
  - - - 🔗Importance: TCO is especially important when evaluating several alternatives.
      - 🔗Problem: Cost estimates often understate indirect costs.
      - 🔗Framework: Rapid Economic Justification (REJ) is a related framework/methodology.
- - - - :star: Simplifies Complexity: It breaks down complex systems and processes into simpler, more understandable parts.
      - :star: Aids Analysis: Helps in understanding the different activities within a system, identifying potential overlaps between functions, and verifying that all necessary components are included.
      - :star: Supports Design and Development: Used in fields like software engineering and business analysis for system design, requirements analysis, and understanding how different parts of a project fit together.
      - :star: Facilitates Management: Helps project managers understand and manage the elements of a project by simplifying tasks and identifying interconnections.
  - - - :star: Improved Efficiency: By simplifying complex processes, modeling helps uncover opportunities to streamline operations and reduce costs.
      - :star: Enhanced Communication: Visual models provide a common language for teams to discuss processes and process improvements, fostering better collaboration.
      - :star: Identification of Problems: Modeling clearly reveals bottlenecks, redundancies, and other operational issues that can hinder productivity.
      - :star: Support for Automation: A well-defined and optimized process model serves as a foundation for automating workflows, ensuring consistent execution.
      - :star: Better Decision-Making: By offering a data-driven and quantitative view of how work is done, modeling provides actionable insights for strategic improvements.
- - - - :star: Structured brainstorming
      - :star: Unstructured brainstorming
